I. Authority and Background
The Department of Energy (``DOE'') is authorized to establish and
amend energy conservation standards and test procedures for small
electric motors and electric motors.\1\ (42 U.S.C. 6311(1)(A); 42
U.S.C. 6317(b)) The current DOE test procedures for small electric
motors appear at subpart X, part 431 of Title 10 of the Code of Federal
Regulations (``CFR''). See 10 CFR 431.444. The current DOE test
procedures for electric motors appear in appendix B to subpart
[[Page 6]]
B of 10 CFR part 431 (``Appendix B''). The following sections discuss
DOE's authority to amend test procedures for small electric motors and
electric motors, as well as relevant background information regarding
DOE's consideration of test procedures for these motors.
---------------------------------------------------------------------------
\1\ EPCA authorized DOE to prescribe test procedures and energy
conservation standards for small electric motors pending a
determination of feasibility and justification (42 U.S.C. 6317(b)),
completed on July 10, 2006. 71 FR 38799. DOE is obligated to review
(and amend as needed) its test procedures and standards under 42
U.S.C. 6314(a) and 6316(a).
---------------------------------------------------------------------------
A. Authority
The Energy Policy and Conservation Act, as amended (``EPCA'') \2\
(42 U.S.C. 6291-6317), among other things, authorizes DOE to regulate
the energy efficiency of a number of consumer products and industrial
equipment. Title III, Part C \3\ of EPCA, added by Title IV, section
441(a) of the National Energy Conservation Policy Act (Pub. L. 95-619
(Nov. 9, 1978)), established the Energy Conservation Program for
Certain Industrial Equipment, which set forth a variety of provisions
designed to improve the energy efficiency of certain industrial
equipment. Later, the Energy Policy Act of 1992, Public Law 102-486
(October 24, 1992), further amended EPCA by adding, among other things,
provisions governing the regulation of small electric motors. EPCA was
further amended by the American Energy Manufacturing Technical
Corrections Act, Public Law 112-210 (December 18, 2012), which
explicitly permitted DOE to examine the possibility of regulating
``other motors'' in addition to those electric and small electric
motors that Congress had already otherwise defined and required DOE to
regulate. (42 U.S.C. 6311(1)(A), 42 U.S.C. 6311(2)(B)(xiii); 42 U.S.C.
6317(b))
---------------------------------------------------------------------------
\2\ All references to EPCA in this document refer to the statute
as amended through America's Water Infrastructure Act of 2018,
Public Law 115-270 (Oct. 23, 2018).
\3\ For editorial purposes, upon codification into the U.S.
Code, Part C was re-designated as Part A-1.
---------------------------------------------------------------------------
The energy conservation program under EPCA consists essentially of
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation
standards, and (4) certification and enforcement procedures. Relevant
provisions of EPCA include definitions (42 U.S.C. 6311), test
procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 6315),
energy conservation standards (42 U.S.C. 6313), and the authority to
require information and reports from manufacturers (42 U.S.C. 6316).
EPCA includes specific authority for DOE to establish test procedures
and standards for small electric motors. (42 U.S.C. 6317(b))
Federal energy efficiency requirements for covered equipment
established under EPCA generally supersede State laws and regulations
concerning energy conservation testing, labeling, and standards. (42
U.S.C. 6316(a) and (b); 42 U.S.C. 6297)
The Federal testing requirements consist of test procedures that
manufacturers of covered equipment must use as the basis for: (1)
Certifying to DOE that their equipment complies with the applicable
energy conservation standards adopted pursuant to EPCA (42 U.S.C.
6316(a); 42 U.S.C. 6295(s)), and (2) making representations about the
efficiency of that equipment. (42 U.S.C. 6314(d)) Similarly, DOE uses
these test procedures to determine whether the equipment complies with
relevant standards promulgated under EPCA. (42 U.S.C. 6316(a); 42
U.S.C. 6295(s))
Under 42 U.S.C. 6314, EPCA sets forth criteria and procedures for
prescribing and amending test procedures for covered equipment. EPCA
provides in relevant part that any test procedures prescribed or
amended under this section must be reasonably designed to produce test
results which reflect the energy efficiency, energy use, or estimated
annual operating cost of covered equipment during a representative
average use cycle and requires that test procedures not be unduly
burdensome to conduct. (42 U.S.C. 6314(a)(2))
In addition, if DOE determines that a test procedure amendment is
warranted, it must publish test procedures and offer the public an
opportunity to present oral and written comments on them. (42 U.S.C.
6314(b))
EPCA also requires that, at least once every 7 years, DOE evaluate
test procedures for each type of covered equipment including small
electric motors to determine whether amended test procedures would more
accurately or fully comply with the requirements for the test
procedures to not be unduly burdensome to conduct and be reasonably
designed to produce test results that reflect the energy efficiency,
energy use, and estimated operating costs during a representative
average use cycle. (42 U.S.C. 6314(a)(1)) If the Secretary determines
that a test procedure amendment is warranted, the Secretary must
publish test procedures in the Federal Register and afford interested
persons an opportunity (of not less than 45 days' duration) to present
oral and written data, views, and arguments on the test procedures. (42
U.S.C. 6314(b)) DOE is publishing this final rule to satisfy the 7-year
review requirement for small electric motors specified in EPCA, which
requires that DOE publish either a final rule amending the test
procedures or a determination that amended test procedures are not
required. (42 U.S.C. 6314(a)(1)(A)) This final rule also responds to
petitions for rulemaking received from the National Electrical
Manufacturers Association (``NEMA'') and Underwriters Laboratory
(``UL'') pertaining to small electric motors and electric motors. (See
section I.B)
B. Background
EPCA defines ``small electric motor,'' as ``a NEMA general purpose
alternating current single-speed induction motor, built in a two-digit
frame number series in accordance with NEMA Standards Publication MG 1-
1987.'' (42 U.S.C. 6311(13)(G)) EPCA directed DOE to establish a test
procedure for those small electric motors for which DOE makes a
determination that energy conservation standards would be
technologically feasible and economically justified and would result in
significant energy savings. (42 U.S.C. 6317(b)(1)) On July 10, 2006,
DOE published its determination that energy conservation standards for
certain polyphase and certain single-phase, capacitor-start, induction-
run, small electric motors are technologically feasible and
economically justified, and would result in significant energy savings.
71 FR 38799. DOE later adopted test procedures for small electric
motors. 74 FR 32059 (July 7, 2009) (``July 2009 final rule''). EPCA
also required that following establishment of the required test
procedures, DOE establish energy conservation standards for those small
electric motors for which test procedures were prescribed. (42 U.S.C.
6317(b)(2)) DOE complied with this requirement when it established
energy conservation standards for small electric motors. 75 FR 10874
(March 9, 2010) (``March 2010 final rule'').\4\
---------------------------------------------------------------------------
\4\ A technical correction was published on April 5, 2010, to
correct the compliance date. 75 FR 17036.
---------------------------------------------------------------------------
Subsequently, DOE published an update to the test procedures for
small electric motors on May 4, 2012. 77 FR 26608. The test procedures
for small electric motors appear at 10 CFR 431.444, and incorporate
certain industry standards from the Institute of Electrical and
Electronics Engineers (``IEEE'') and Canadian Standards Association
(``CSA''), as listed in Table I-1.

More recently, DOE published a request for information pertaining
to the test procedures for small electric motors and electric motors in
July 2017. 82 FR 35468 (July 31, 2017) (``July 2017 RFI''). In the July
2017 RFI, DOE solicited public comments, data, and information on all
aspects of, and any issues or problems with, the existing DOE test
procedure for small electric motors, including on any needed updates or
revisions. DOE also discussed potential categories of electric motors
(as defined at 10 CFR 431.12) that may be considered in future DOE test
procedures. 82 FR 35470-35474. At the request of commenters, DOE
extended the comment period for the July 2017 RFI in a notice published
on August 30, 2017. 82 FR 41179.
Separate from the July 2017 RFI, NEMA and Underwriter Laboratories
(``UL'') independently submitted written petitions requesting that
certain portions of International Electrotechnical Commission (``IEC'')
60034-2-1:2014 be adopted as a permitted alternative test method for
small electric motors and electric motors.\5\ DOE published a notice of
receipt of these petitions on November 2, 2017. 82 FR 50844 (``November
2017 notice of petition'').
---------------------------------------------------------------------------
\5\ The NEMA petition and work paper are available at https://www.regulations.gov/document?D=EERE-2017-BT-TP-0047-0028. The UL
petition and supporting documentation are available at https://www.regulations.gov/document?D=EERE-2017-BT-TP-0047-0029.
---------------------------------------------------------------------------
On April 23, 2019, DOE published a NOPR (``April 2019 NOPR'')
responding to the comments received to the July 2017 RFI and proposing
to further clarify the test procedures for small electric motors and
incorporate an additional industry test method, IEC 60034-2-1:2014
industry test standard, for testing small electric motors and electric
motors.\6\ 84 FR 17004 (April 23, 2019). The April 2019 NOPR also
addressed the test procedures for electric motors in response to the
November 2017 notice of petition. Id.

DOE has determined that the amendments described in section III of
this notice will not alter the measured efficiency of small electric
motors or electric motors, and that the test procedures will not be
unduly burdensome to conduct. Discussion of DOE's actions are addressed
in detail in section III of this document.
III. Discussion
A. Scope of the Test Procedures for Currently Regulated Small Electric
Motors and Electric Motors
This final rule does not change the scope of the test procedure
with respect to small electric motors and electric motors. The scope of
the test procedure as applied to currently regulated motors is
discussed in sections III.A.1 through III.A.3.
1. Definition of ``Small Electric Motor''
EPCA defines the term ``small electric motor'' as ``a NEMA general
purpose alternating current single-speed induction motor, built in a
two-digit frame number series in accordance with NEMA Standards
Publication MG 1-1987.'' 42 U.S.C. 6311(13)(G) In the July 2009 final
rule, DOE adopted a modified version of this definition at 10 CFR
431.442 to specify that the term also encompasses those motors that are
built as ``IEC metric equivalent motors.'' 74 FR 32059, 32062; 10 CFR
431.442. This specification ensures that motors that otherwise satisfy
the small electric motor definition but are built in accordance with
metric-units are treated in a like manner as their counterparts that
are built in accordance with U.S. customary units of measurement.
The current definition at 10 CFR 431.442 lists the criteria that
must be met for a motor to be defined as a ``small electric motor.''
Under these criteria, a small electric motor is:
A NEMA general purpose motor \8\ that:
---------------------------------------------------------------------------
\8\ In response to questions from NEMA and various motor
manufacturers, DOE issued a guidance document that identifies some
key design elements for consideration when determining whether a
given individual motor meets the small electric motor definition and
is subject to the energy conservation standards promulgated for
small electric motors. See https://www.regulations.gov/document?D=EERE-2017-BT-TP-0047-0082.
---------------------------------------------------------------------------
Uses alternating current,
Is single-speed,
Is an induction motor; and
Is built in a two-digit frame size in accordance with NEMA
Standards Publication MG 1-1987, including IEC metric equivalent
motors. See 10 CFR 431.442.
DOE did not propose to modify the definition of ``small electric
motor'' in the April 2019 NOPR (See 84 FR 17004, 17007) and DOE did not
receive any comments suggesting that it do so. Accordingly, DOE is not
modifying the current definition of small electric motor.
2. Scope of the Small Electric Motor Test Procedure
In the March 2010 final rule, DOE concluded that the following
motor topologies satisfy the small electric motor definition:
Capacitor-start induction-run (``CSIR''), capacitor-start capacitor-run
(``CSCR''), and certain polyphase motors. 75 FR 10874, 10882-10883. DOE
determined for purposes of its regulations that only CSIR, CSCR, and
polyphase motors are able to meet the performance requirements in NEMA
MG1 and are widely considered general purpose alternating current
motors, as shown by the listings found in manufacturers' catalogs. Id.
As such, DOE concluded that CSIR, CSCR, and polyphase motors are the
only motor categories that would satisfy the relevant criteria set by
EPCA to be regulated as small electric motors. 75 FR 10874, 10883. DOE
established test procedures for these three topologies in subpart X of
10 CFR part 431.
In response to the April 2019 NOPR, DOE received a number of
comments relevant to the scope of applicability for the small electric
motors test procedures. NEMA commented that there have been no
significant technological advancements for small electric motors since
the last rulemaking and that it supported maintaining the current scope
of applicability. (NEMA, No. 84 at p. 2) \9\ AHAM and AHRI also
supported the current scope of the test procedure, (AHAM and AHRI, No.
85 at pp. 1-2), and opposed developing separate test procedures and
energy conservation standards for special and definite purpose motors.
In their view, an expanded test procedure scope would increase costs
(equipment cost,
[[Page 9]]
testing costs, and costs related to certification) and would not
increase energy savings because original equipment manufacturers
already consider efficient small electric motors as a design option to
meet the energy conservation standards for those finished products
regulated by DOE. Id. They added that an expanded scope to include
definite and special purpose motors could impact the availability of
replacement parts. They noted that home appliances and heating,
ventilation, and air conditioning (``HVAC'') equipment have long
lifetimes and often have sizing constraints. They asserted that, if
motor sizes increase in response to efficiency requirements,
replacement motors may no longer fit in those products using small
electric motors.\10\ (AHAM and AHRI, No. 85 at p. 3)

written comment: (1) Made by NEMA; (2) recorded in document number
84 that is filed in the docket of this test procedure rulemaking
(Docket No. EERE-2017-BT-TP-0047) and available for review at http://www.regulations.gov; and (3) which appears on page 2 of document
number 84.
\10\ One of the methods for improving the efficiency of an
electric motor is to increase its stack length--i.e., the number of
rotors and stators that are stacked together to fit along a given
motor's shaft. While this may increase the efficiency of a given
motor with specified horsepower and torque ratings, it also results
in increasing the overall dimensions of the motor, thereby affecting
its ability to fit within a given application.
---------------------------------------------------------------------------
The CA IOUs and Efficiency Advocates supported expanding the scope
of the small electric motors test procedures to cover a broader range
of motors. In their view, DOE should expand the scope of the small
electric motors test procedure to address a wide range of motors that
the market considers ``small.'' (CA IOUs, No. 86 at p. 2) The
Efficiency Advocates stated that DOE previously found that motors with
the same characteristics as currently regulated small electric motors
are widely available in larger horsepower ranges. They referenced DOE's
preliminary identification presented in the July 2017 RFI of 11 motor
categories that may represent significant shipment volumes and energy
consumption and that were capable of being tested using existing test
procedures. The Efficiency Advocates stated that these motor categories
include both inefficient designs (e.g., shaded-pole) and high-
efficiency topologies (e.g., permanent magnet and switched reluctance).
(Efficiency Advocates, No. 87 at p. 1)
As previously stated, DOE is not modifying the test procedure's
scope. The test procedure continues to apply only to small electric
motors that are currently subject to DOE's existing test procedure at
10 CFR 431.444. As explained in the March 2010 final rule, under the
definition of ``small electric motor'' prescribed by EPCA, CSIR, CSCR,
and polyphase motors are the only motor categories that are general
purpose motors (which is a key element to the statutory definition of
this term), and therefore the only categories for which DOE has
authority to regulate as a small electric motor. 75 FR 10874, 10881.
Special purpose and definite purpose motors are not general purpose
motors and therefore are not covered under the statutory or regulatory
definition of ``small electric motor'' and are not ``small electric
motors'' under DOE's statutory or regulatory framework.\11\ (See 42
U.S.C. 6311(13)(G) (defining ``small electric motor''), 42 U.S.C.
6311(13)(C) (defining ``definite purpose motor'') and 42 U.S.C.
6311(13)(D) (defining ``special purpose motor''); see also generally 10
CFR 431.442)
---------------------------------------------------------------------------
\11\ Under EPCA, the term ``definite purpose motor'' means ``any
motor designed in standard ratings with standard operating
characteristics or standard mechanical construction for use under
service conditions other than usual or for use on a particular type
of application and which cannot be used in most general purpose
applications.'' 42 U.S.C. 6311(13)(C). Similarly, EPCA defines a
``special purpose motor'' as ``any motor, other than a general
purpose motor or definite purpose motor, which has special operating
characteristics or special mechanical construction, or both,
designed for a particular application.'' 42 U.S.C. 6311(13)(D).
Given that EPCA treats these motors as being separate from small
electric motors, and that these two categories of motors generally
fall outside of general purpose motor applications, coverage of
definite purpose and special purpose motors cannot be accomplished
through DOE's authority to regulate small electric motors.
---------------------------------------------------------------------------
In the July 2017 RFI, DOE indicated that it may consider setting
test procedures for electric motors that are considered ``small'' by
customers and the electric motors industry, but that are not currently
subject to the small electric motor test procedure. 82 FR 35468, 35470-
35471. DOE discussed that the motors identified in the July 2017 RFI
may have similarities to motors that are currently regulated as small
electric motors (such as horsepower) and may be used in similar
applications. However, DOE had not concluded that the identified motors
are small electric motors or electric motors (nor did DOE propose such
a conclusion). While certain commenters urged DOE to expand the scope
of the test procedures to include some or all of the 11 categories of
motors identified in the July 2017 RFI, these commenters did not
provide an explanation for how such expansion would be consistent with
DOE's authority under EPCA, or how such motors should be classified and
tested.
AHAM and AHRI referenced the statutory exemption regarding the
application of energy conservation standards for small electric motors
that are components of covered products (42 U.S.C. 6317(b)(3)) and
requested that DOE interpret the exemption to apply to all small
electric motors destined for or used in covered products or equipment.
(AHAM and AHRI, No. 85 at p. 4)
By statute, the small electric motor standards established by DOE
shall not apply to any such motor that is a component of a covered
product, or of covered equipment. (42 U.S.C. 6317(b)(3)) Accordingly,
consistent with the statute, the test procedure as amended in this
final rule does not apply to a motor that is a component of a covered
product, or of covered equipment.
3. Scope of the Electric Motor Test Procedure
As noted in section I.B, this final rule also addresses the test
procedure for electric motors in response to a petition for
rulemaking.\12\ The current electric motor test procedure is codified
at subpart B of 10 CFR part 431. DOE did not propose to amend the scope
of the electric motor test procedure. Accordingly, this final rule does
not change the scope of that test procedure.
---------------------------------------------------------------------------
\12\ The NEMA petition and work paper are available at https://www.regulations.gov/document?D=EERE-2017-BT-TP-0047-0028. The UL
petition and supporting documentation are available at https://www.regulations.gov/document?D=EERE-2017-BT-TP-0047-0029.
---------------------------------------------------------------------------
B. Industry Standards
The DOE test procedures rely on industry standards that are
incorporated by reference at 10 CFR 431.443 for small electric motors
and 10 CFR 431.15 for electric motors. Specifically, the existing DOE
test procedures for small electric motors and electric motors rely on
the following test methods:
(1) For single-phase small electric motors: Either IEEE 114-2010,
or CSA C747-09 (see 10 CFR 431.443(b)(1); 10 CFR 431.443(c)(2); 10 CFR
431.444(b)(1));
(2) For polyphase small electric motors of less than or equal to 1
hp, either Section 6.3 ``Efficiency Test Method A, Input-Output'' of
IEEE 112-2004, ``IEEE Standard Test Procedure for Polyphase Induction
Motors and Generators'' (``IEEE 112-2004'') or CSA C747-09 (see 10 CFR
431.443(b)(1); 10 CFR 431.443(c)(1)(i); 10 CFR 431.444(b)(2)); and
(3) For polyphase small electric motors of greater than 1 hp and
electric motors, either Section 6.4 ``Efficiency Test Method B, Input-
Output with Loss Segregation'' of IEEE 112-2004; or CSA C390-10 (see 10
CFR 431.443(b)(2); 10 CFR 431.443(c)(1)(ii); 10 CFR 431.444(b)(3); 10
CFR 431.16 and Appendix B).
[[Page 10]]
In preparation for the April 2019 NOPR, DOE reviewed each of the
referenced industry standards to determine whether they still represent
the most current procedures developed by industry. On February 14,
2018, IEEE published an updated edition of the IEEE 112 standard. The
other referenced industry standards incorporated into DOE's test
procedure developed by CSA and IEEE remain current or have been
reaffirmed without changes.\13\ This final rule maintains the
references to IEEE 114-2010, CSA C390-10, and CSA C747-09. As discussed
in Section III.B.1 of this document, DOE is updating the reference to
IEEE 112 to reference the updated IEEE 112-2017 standard. As discussed
in section III.B.2, DOE is also incorporating by reference IEC 60034-2-
1:2014 as an additional alternative test procedure for small electric
motors and electric motors. IEEE 112-2017 and IEC 60034-2-1:2014 are
discussed in the following paragraphs.
---------------------------------------------------------------------------
\13\ Both CSA C747-09 and CSA C390-10 have been reaffirmed in
2014 and 2015, respectively.
---------------------------------------------------------------------------
1. IEEE 112-2017
On February 14, 2018, IEEE approved IEEE 112-2017, ``IEEE Standard
Test Procedure for Polyphase Induction Motors and Generators.'' DOE
conducted a full review of that revised testing standard to identify
any changes made relative to the industry test methods that are
incorporated by reference from IEEE 112-2004. In the April 2019 NOPR,
DOE highlighted the following changes between the 2004 and 2017
version: (1) Section 4, ``Measurements'' of IEEE 112-2017, includes
several updates regarding instrument selection and measurement
accuracy; and (2) the method for calculating core loss used in Section
6.4, ``Efficiency Test Method B--Input-Output with Loss Segregation''
of IEEE 112-2017 was revised and aligned with the efficiency test
method specified in CSA C390-10, currently incorporated by reference at
10 CFR 431.443(b)(2). 84 FR 17004, 17011. DOE further noted that this
change also aligns with the Method 2-1-1B approach of IEC 60034-2-
1:2014. Id. In the April 2019 NOPR, DOE noted that the revisions in the
2017 version aligned measurement, calculation methods, and
instrumentation requirements with industry practice, and that the
differences between the IEEE 112-2004 and IEEE 112-2017 calculation
methods were minimal, with both tests resulting in an accurate and
similar measurement of efficiency. 84 FR 17004, 17011-17012. DOE noted
that, in the small electric motor and electric motor final rule
published on May 4, 2012, commenters indicated the difference in
efficiency outcome between IEEE 112-2004 and CSA C390-10 to be within
0.2 percent. 84 FR 17004, 17012 citing 77 FR 26608, 26622. DOE stated
that the core loss calculation in IEEE 112-2017 aligns with the core
loss calculation in CSA C390-10, and that based on this comparison of
IEEE 112-2004 and CSA C390-10, the impact of the core loss calculation
between IEEE 112-2004 and IEEE 112-2017 should be no greater than 0.2
percent. 84 FR 17004, 17012. To avoid any potential need to retest
motors that have relied on IEEE 112-2004 for purposes of compliance,
DOE proposed to incorporate the IEEE 112-2017 test method as an
alternative to the test methods incorporated in the current test
procedure, while retaining the currently incorporated IEEE 112-2004
method, and requested data comparing the results of the IEEE 112-2004
and IEEE 112-2017. 84 FR 17004, 17012.
In response to the April 2019 NOPR, NEMA supported updating the
reference to IEEE 112 to its latest 2017 version and noted that IEEE
112-2017 Method B resolves previous technical differences between IEEE
112-2004 Method B and CSA C390-10. NEMA added that both versions of
IEEE 112 led to equivalent results. (NEMA, No. 84 at p. 2) The
Efficiency Advocates supported referencing the latest version of IEEE
112 and urged DOE not to continue referencing the older version since
referencing two different procedures introduces additional variability
into the DOE test procedure. (Efficiency Advocates, No. 87 at p. 2)
DOE has determined that IEEE 112-2017 will result in an accurate
and similar measurement of efficiency as compared to IEEE 112-2004.
Given the expected variation of tested efficiency values for small
electric motors and electric motors due to manufacturing and material
differences, any minor differences between IEEE 112-2004 and IEEE 112-
2017 will not result in any significant change in overall energy
efficiency test results. This determination is consistent with DOE's
prior comparison of IEEE 112-2004 and CSA C390-10, as affirmed by
NEMA's comment. Given the functional equivalency of testing under IEEE
112-2004 and IEEE 112-2017, DOE is incorporating IEEE 112-2017 in place
of IEEE 112-2004. Referencing only the most recent version of IEEE 112
avoids the potential concerns identified by the Efficiency Advocates.
Additionally, incorporating this update further aligns DOE's test
procedures with current industry practice and reduces manufacturer test
burden, while ensuring that motors that have demonstrated compliance
under IEEE 112-2004 methods do not require retesting (see section
III.F.1 for more details).
Therefore, the updates to IEEE 112-2017 are in the following
sections of the CFR (as amended by this final rule):
For small electric motors, 10 CFR 431.443 ``Materials incorporated
by reference,'' paragraph (d)(1); 10 CFR 431.444 ``Test procedures for
the measurement of energy efficiency,'' paragraphs (b)(1)(vi),
(b)(3)(i) and (b)(4)(i); and 10 CFR 431.447 ``Department of Energy
recognition of nationally recognized certification programs,''
paragraphs (b)(4) and (c)(4).
For electric motors, 10 CFR 431.12 ``Definitions'' (the definition
for ``accreditation''); 10 CFR 431.15 ``Materials incorporated by
reference,'' paragraph (d)(1); 10 CFR 431.19 ``Department of Energy
recognition of accreditation bodies,'' paragraphs (b)(4) and (c)(4); 10
CFR 431.20 ``Department of Energy recognition of nationally recognized
certification programs,'' paragraphs (b)(4) and (c)(4); and Appendix B
to Subpart B of Part 431 ``Uniform test method for measuring nominal
full load efficiency of electric motors,'' Sections 0(d),\14\ 2(3), 3.
---------------------------------------------------------------------------
\14\ Appendix B to subpart B of part 431 was reorganized to
include a new section 0 in this final rule. Section 0 details the
applicability of the industry testing standards incorporated by
reference and provides the specific provisions of the industry
testing standards that are applicable to the DOE test procedure and
the sections of the DOE test procedure in which the industry testing
standards are incorporated. Because of this re-organization, the
instruction in section 3 of Appendix B to subpart B of part 431
regarding the applicability of subsequent editions of the
incorporated industry testing standards was duplicative to those in
section 0, and therefore removed in this final rule.
---------------------------------------------------------------------------
2. IEC 60034-2-1:2014
As discussed in section I.B, NEMA and UL independently submitted
written petitions requesting that certain portions of IEC 60034-2-
1:2014 be adopted as a permitted alternative test method for small
electric motors and electric motors. Specifically, NEMA's petition
requested that DOE incorporate IEC 60034-2-1:2014 Method 2-1-1B \15\ as
an alternative to IEEE 112-2004 Test Method B and CSA C390-10, which
are currently referenced in Appendix B. (NEMA, No. 28.2 at p. 1) UL
requested that (1) IEC 60034-2-1:2014 Method 2-1-1B be approved for
Appendix B and section 431.444 of 10 CFR part 431 (as an alternative to
IEEE 112-2004 Test
[[Page 11]]
Method B and CSA C390-10) and (2) that IEC 60034-2-1:2014 Method 2-1-1A
\16\ be approved for section 431.444 of 10 CFR part 431 (as an
alternative to IEEE 112-2004 Test method A, IEEE 114-2010, and CSA
C747-09). (UL, No. 29.1 at p. 1) The NEMA and UL petitions included and
referenced papers that compare the testing methodologies presented in
IEC 60034-2-1:2014 to the IEEE and CSA standards currently referenced
in the small electric motors and electric motors test procedures at 10
CFR part 431.
---------------------------------------------------------------------------
\15\ IEC 60034-2-1:2014 Method 2-1-1B (2014), ``Rotating
Electrical Machines--Part 2-1: Standard methods for determining
losses and efficiency from tests (excluding machines for traction
vehicles),'' ``Summation of losses, additional load losses according
to the method of residual loss.''
\16\ IEC 60034-2-1:2014 Method 2-1-1A (2014), ``Rotating
Electrical Machines--Part 2-1: Standard methods for determining
losses and efficiency from tests (excluding machines for traction
vehicles),'' ``Direct Measurement of Input and Output.''
---------------------------------------------------------------------------
The NEMA petition included a ``work paper'' that summarizes an
evaluation conducted by the NEMA Motor and Generator Section technical
committee, which found that IEC 60034-2-1:2014 Method 2-1-1B was a
suitable alternative to the IEEE 112-2004 Test Method B and CSA C390-10
test methods. (NEMA, No. 28.3 at p. 1) This evaluation relied on (1)
comparison of instrumentation accuracy, test method, and calculation
approach among the IEC, IEEE, and CSA industry standards, (2) analysis
of test results from over 500 motors tested at the Hydro-Qu[eacute]bec
Research Institute, and (3) reference to one scientific research paper
(the ``Angers et al. study''), which also concluded that all three
methods provide results that are very closely aligned. (NEMA, No. 28.3
at pp. 1-3)
The UL petition included two papers comparing the IEC 60034-2-1
test methods with the respective IEEE and CSA standards. The first
paper was the Angers et. al. study, which concluded that the IEC 60034-
2-1:2014 Method 2-1-1B test method provides results that are very
closely aligned with the IEEE 112-2004 Test Method B and CSA C390-10
test methods. (UL, No. 29.2 at pp. 1-8) The second paper, written by
IEEE member Wenping Cao, compared the IEEE 112 and IEC 60034-2-1
standards and concluded that the resulting efficiency values were found
to be equal or otherwise closely aligned. (UL, No. 29.3 at p. 7) UL
requested that DOE incorporate IEC 60034-2-1:2014 Method 2-1-1B as an
alternative to IEEE 112-2004 Test Method B and CSA C390-10 because of
an increased use of the IEC 60034-2-1:2014 Method 2-1-1B. (UL, No 29.1
at p.1) In its comments, UL did not quantify how broadly IEC 60034-2-
1:2014 Method 2-1-1B is currently being used.
In the April 2019 NOPR, DOE proposed to permit use of IEC 60034-2-
1:2014 Method 2-1-1A, with certain limitations regarding torque
measurement, as an alternative to IEEE 112-2004 Test Method B and CSA
C390-10. 84 FR 17004, 17012-17013. DOE also proposed to permit use of
IEC 60034-2-1:2014 Method 2-1-1B as a permitted alternative to the test
methods IEEE 112-2004 Test Method B and CSA C390-10. 84 FR 17004,
17014. DOE requested comment on its proposals regarding IEC 60034-2-
1:2014 Method 2-1-1A and Method 2-1-1B, including data comparing test
results of those standards with the corresponding CSA and IEEE test
procedures. 84 FR 17004, 17013-17014.
The CA IOUs questioned whether alternative testing standards are
truly equivalent to one another and commented that DOE should evaluate
the possibility that one equivalent test procedure may produce a
disproportionately favorable result compared to another. The CA IOUs
recommended that, to avoid confusion in the market and maintain
consistency in results, the DOE should specify a single version of a
test procedure to be used for enforcement testing. (CA IOUs, No. 86 at
p. 2-3)
As discussed in the April 2019 NOPR and in the following sections,
DOE evaluated the various industry tests as well as the results of
comparative testing and concludes that the relevant test methods in IEC
60034-2-1:2014 are equivalent to the corresponding industry standards
currently referenced in the test procedures for small electric motors
and electric motors. Permitting use of the test methods in IEC 60034-2-
1:2014 further harmonizes DOE's test standards with industry and
reduces test burden while ensuring that the test procedure reflects the
energy efficiency of the relevant motors during a representative
average use cycle.
a. Method 2-1-1A
Among multiple testing methods provided in IEC 60034-2-1:2014,
Method 2-1-1A ``Direct measurement of input and output'' is the
standard's preferred testing method for single-phase motors. It is
based on direct measurement of electrical input power to the motor and
mechanical output power (in the form of torque and speed) from the
motor. This approach is analogous to the methods of the other industry
standards, IEEE 114-2010 and CSA C747-09, currently incorporated by
reference for testing single-phase motors, and IEEE 112-2004 Test
Method A, currently incorporated by reference for the purpose of
testing polyphase motors of output power less than or equal to one
horsepower.
In the April 2019 NOPR, DOE tentatively determined that IEC 60034-
2-1:2014 Method 2-1-1A is likely to produce accurate and reproducible
results that are consistent with results from the other test methods
permitted under subparts X and B of 10 CFR part 431. 84 FR 17004,
17013. DOE proposed to incorporate by reference IEC 60034-2-1:2014
Method 2-1-1A as an alternative to the currently incorporated industry
testing standards IEEE 112-2004 Test Method A and CSA C747-09 in 10 CFR
431.443. Id. However, DOE also initially determined that the process
for dynamometer torque correction in section 6.1.2.2 of IEC 60034-2-
1:2014, Method 2-1-1A is insufficiently described. 84 FR 17004, 17013.
Specifically, IEEE 114-2010 \17\ and CSA C747-09 \18\ contain more
detailed descriptions of torque correction procedures, but both state
that torque correction is not required when torque is measured using
either an inline, rotating torque transducer or stator reaction torque
transducer. The insufficient specificity of IEC 60034-2-1:2014 Method
2-1-1A regarding dynamometer torque correction can be avoided by using
a torque measurement method that does not require correction.
Consequently, DOE proposed to permit use of IEC 60034-2-1:2014 with
limitations to limit torque measurement to methods that do not require
dynamometer torque correction (i.e., either in-line, shaft-coupled,
rotating torque transducers or stationary, stator reaction torque
transducers). 84 FR 17004, 17012-17013.
---------------------------------------------------------------------------
\17\ Section 5.2.1.1.1 of IEEE 114-2010 addressees when torque
correction is required.
\18\ Section 6.7.1 of CSA C747-09 addresses when torque
correction is required.
---------------------------------------------------------------------------
In response to the April 2019 NOPR, NEMA reiterated its support to
have the option of using IEC 60034-2-1:2014 Method 2-1-1A. (NEMA, No.
84 at p. 3) DOE did not receive any other comment on the incorporation
of IEC 60034-2-1:2014 Method 2-1-1A generally, or regarding the
proposal to limit torque measurement.
For the reasons discussed in the April 2019 NOPR, DOE is
referencing IEC 60034-2-1:2014 Method 2-1-1A as an alternative to the
referenced industry testing standards IEEE 112-2017 Test Method A (per
the amendment in this final rule) and CSA C747-09 in 10 CFR 431.443. As
proposed, this final rule requires torque measurement, when using IEC
60034-2-1:2014 Method 2-1-1A, to be made using either in-line, shaft-
coupled, rotating torque transducers or stationary, stator reaction
torque transducers. This change will
[[Page 12]]
further harmonize DOE's test procedures with current industry practice
and reduce manufacturer test burden (see section III.F.1 for more
details).
For small electric motors, DOE is adding a reference to IEC 60034-
2-1 in 10 CFR 431.443 ``Materials incorporated by reference,''
paragraph (c)(2) and making a more specific set of references to IEC
60034-2-1:2014 Method 2-1-1A in 10 CFR 431.444 ``Test procedures for
the measurement of energy efficiency,'' paragraphs (b)(2)(iii) and
(b)(3)(iii) and in 10 CFR 431.447 ``Department of Energy recognition of
nationally recognized certification programs,'' paragraphs (b)(4) and
(c)(4).
In addition, section 6.1.2.2 of IEC 60034-2-1:2014 Method 2-1-1A
specifies that motors under test should be operated at the ``required
load'' until thermal equilibrium is achieved. As required under DOE's
test procedure, the motor must be rated and tested at rated load. For
clarity and consistency, in the April 2019 NOPR, DOE proposed to modify
these instructions by replacing the term ``required load'' with ``rated
load.'' 84 FR 17004, 17013. DOE did not receive any stakeholder
comments on this proposal and is modifying these instructions by
replacing the term ``required load'' with ``rated load.''
Furthermore, IEC 60034-2-1:2014 references IEC 60034-1:2010 and IEC
60051-1:2016 to specify required test conditions and procedures when
applying the test methods for measuring energy efficiency in the
following sections: (1) Section 5.4.1 of IEC 60034-2-1:2014 specifies
that the supply voltage shall be in accordance with sections 7.2 (and
8.3.1 for thermal tests) of IEC 60034-1:2010; (2) section 5.5.2 of IEC
60034-2-1:2014 specifies that the measuring instruments shall have the
equivalent of an accuracy class of 0.2 in case of a direct test and 0.5
in case of an indirect test in accordance with IEC 60051; \19\ and (3)
section 5.7.1 of IEC 60034-2-1:2014 states that the measured resistance
at the end of the thermal test shall be determined in a similar way to
the extrapolation procedure as described in section 8.6.2.3.3 of IEC
60034-1, using the shortest possible time instead of the time interval
specified in Table 5 therein, and extrapolating to zero. Therefore, in
this final rule, DOE is also incorporating by reference IEC 60034-
1:2010 and IEC 60051-1:2016 to specify the test conditions and
procedures as referenced in IEC 60034-2-1:2014.
---------------------------------------------------------------------------
\19\ Section 3.8.2 of IEC 60051-1:2016 defines ``accuracy
class'' as a ``class of measuring instruments, all of which are
intended to comply with a set of specifications regarding
uncertainty.'' Furthermore, IEC 6005-1:2016 specifies that an
accuracy class always specifies a limit of uncertainty, whatever
other metrological characteristics it specifies. While IEC 60051-
1:2006 does not define a metric for this term, in practice, accuracy
classes are used to designate percentage uncertainties. For example,
section 5.5.2 of IEC 60034-2-1:2014 states that ``for an accuracy
class of 0.2, the measuring equipment shall reach an overall
uncertainty of 0.2% of reading at power factor of 1.0.''
---------------------------------------------------------------------------
b. Method 2-1-1B
Among the multiple testing methods provided in IEC 60034-2-1:2014,
Method 2-1-1B ``Summation of losses, additional load losses according
to the method of residual loss'' is the IEC 60034-2-1:2014 standard's
preferred testing method for three-phase motors. This method relies on
the indirect calculation of motor losses using a combination of
measured values (e.g., winding resistance) and assumptions so that
direct measurement of motor torque is not needed. This method is
analogous to the methods of the other industry standards, IEEE 112-2004
and CSA C390-10, currently incorporated by reference for testing
polyphase small electric motors of output power greater than one
horsepower and electric motors.
DOE reviewed IEC 60034-2-1:2014, Method 2-1-1B, and stakeholder
responses to the November 2017 notice of petition, as well as all of
the research papers referenced in the NEMA and UL petitions. The
research papers evaluated IEC 60034-2-1:2014, Method 2-1-1B and the
IEEE 112-2004 Test Method B and CSA C390-10 testing standards with
respect to a comparison of the instrumentation accuracy, test method,
and calculation approach, in addition to an analysis of any variability
of actual test results. DOE also considered a comparison of results
from a round robin test program among 11 participants, which concluded
that the same motor tested at multiple test facilities showed a maximum
deviation of 0.4 percentage points, using the same IEEE
112-2004 Test Method B for each test.\20\ 84 FR 17013-17014. DOE noted
that the largest difference reported by stakeholders between measured
efficiency values using IEC 60034-2-1:2014, Method 2-1-1B and IEEE 112-
2004 Test Method B did not exceed 0.2 percentage points. 84
FR 17004, 17014.

---------------------------------------------------------------------------
DOE initially concluded that (1) these methods are not identical,
but the differences between these standards are within the expected
measurement variation of the existing test procedure; (2) all three
tests would result in measurements of efficiency that would yield the
same results with respect to motor compliance; and (3) given the
variable nature of tested efficiency values for electric motors and
small electric motors due to manufacturing and material differences,
the variation in the calculated efficiency is insignificant and not
likely to result in any significant change in overall energy efficiency
test results. 84 FR 17004, 17014. Accordingly, in the April 2019 NOPR,
DOE proposed to incorporate by reference IEC 60034-2-1:2014 Method 2-1-
1B as an alternative to the currently incorporated industry testing
standards IEEE 112-2004 Test Method B and CSA C390-10 and to IEEE 112-
2017 Test Method B. Id.
In response to the April 2019 NOPR, NEMA reaffirmed its request for
the addition of IEC 60034-2-1:2014 Method 2-1-1B as an alternative test
standard for polyphase small electric motors greater than 1 hp and
electric motors. (NEMA, No. 84 at p. 3)
Based on the considerations presented in the April 2019 NOPR, DOE
affirms its initial conclusions regarding IEC 60034-2-1:2014 Method 2-
1-1B. Allowing manufacturers to test according to IEC 60034-2-1:2014
Method 2-1-1B further harmonizes DOE's test procedures with current
industry practice and reduces manufacturer test burden (see section
III.F.2 for more details) while ensuring that the test procedure
reflects the energy efficiency of the relevant motors during a
representative average use cycle. Therefore, in this final rule, DOE is
referencing IEC 60034-2-1:2014 Method 2-1-1B as a permitted alternative
to the current test methods IEEE 112-2004 Test Method B (which in this
final rule will be replaced with IEEE 112-2017 Test Method B) and CSA
C390-10. In addition, as described in section III.B.2.a, DOE is also
incorporating by reference IEC 60034-1:2010 and IEC 60051-1:2016, which
specify the test conditions and procedures for IEC 60034-2-1:2014.
Accordingly, reference to IEC 60034-2-1:2014 Method 2-1-1B is being
added to the following sections of the CFR:
For small electric motors, IEC 60034-2-1 is referenced in 10 CFR
431.443 ``Materials incorporated by reference,'' paragraph (c)(2). The
specific references to IEC 60034-2-1:2014 Method 2-1-1B are in 10 CFR
431.444 ``Test procedures for the measurement of energy efficiency,''
paragraph (b)(4)(iii) and 10 CFR 431.447 ``Department of Energy
recognition of nationally recognized
[[Page 13]]
certification programs,'' paragraphs (b)(4) and (c)(4).
For electric motors, IEC 60034-2-1 is referenced in 10 CFR 431.12
``Definitions'' (the definition for ``accreditation''); and 10 CFR
431.15 ``Materials incorporated by reference,'' paragraph (c)(3). The
specific references to IEC 60034-2-1:2014 Method 2-1-1B are in 10 CFR
431.19 ``Department of Energy recognition of accreditation bodies,''
paragraphs (b)(4) and (c)(4); 10 CFR 431.20 ``Department of Energy
recognition of nationally recognized certification programs,''
paragraphs (b)(4) and (c)(4); and Appendix B to Subpart B of Part 431
``Uniform test method for measuring nominal full load efficiency of
electric motors,'' Sections 2(2) and 3.
C. Rated Output Power and Breakdown Torque of Small Electric Motors
The current regulations for small electric motors specify that the
metric for energy conservation standards, average full-load efficiency,
is to be measured at ``full rated load.'' 10 CFR 431.442. The industry
testing standards referenced in the small electric motor test procedure
do not provide a method to determine the rated load of the tested unit
but instead rely on manufacturer-specified output power, which is
typically listed on a motor's nameplate, to determine average full-load
efficiency at full rated load.\21\ The industry standards do not define
rated output power; rather, the output power is a manufacturer
declaration.
---------------------------------------------------------------------------
\21\ See e.g., CSA C747-09, Section 3, Definition of ``full
load''; CSA C390-10, Section 3.1, Definition of ``rating''; IEEE
112-2017, Section 3.3.2 (``Specified temperature''); and IEEE 114-
2010, Section 8.2 (``Determination of efficiency'').
---------------------------------------------------------------------------
As explained in the April 2019 NOPR, the motors subject to the
small electric motors test procedures are capable of operating over a
continuous range of loads. 84 FR 17004, 17014. For example, a motor
that is rated at 1 hp is also capable of delivering 0.75 hp, but likely
with a different speed, torque, and efficiency than those of when it is
delivering its rated load of 1 hp. The output power of the motor
depends on the load and the design of the motor. Therefore, the load
point at which the motor must be tested is not an intrinsic parameter
of the motor, but rather a parameter that must be defined or specified.
The test's load point is relevant to efficiency testing because the
efficiency of small electric motors varies according to load.
In the April 2019 NOPR, DOE proposed to define rated output power
using breakdown torque as specified in NEMA MG 1-2016. 84 FR 17004,
17014-17016. In concept, breakdown torque describes the maximum torque
the motor can develop without slowing down and stalling. The maximum
torque over the entire speed range could occur at a different condition
(e.g., the motor start-up, zero speed condition) than the breakdown
condition. As explained in the April 2019 NOPR, breakdown torque
corresponds to a local maximum torque (on a plot of torque versus
speed) that is nearest to the rated torque. 84 FR 17004, 17014. The
phrase ``abrupt drop in speed'' corresponds to the expectation that the
motor will slow down or stall if the load increases and indicates that
minor reductions in speed observed due to measurement sensitivities are
not considered.
The breakdown torque for a specific horsepower rating is specified
as a range as a function of input frequency and synchronous speed of
the motor in two tables: Table 10-5 of NEMA MG 1-2016, which applies to
induction motors, except permanent-split capacitor (``PSC'') and
shaded-pole motors; and Table 10-6 of NEMA MG 1-2016, which applies to
shaded-pole and PSC motors for fan and pump applications. For polyphase
motors, section 12.37 of NEMA MG 1-2016 specifies that the breakdown
torque of a general-purpose polyphase squirrel-cage small motor shall
not be less than 140 percent of the breakdown torque of a single-phase
general purpose motor of the same horsepower and speed rating.
In the April 2019 NOPR, DOE initially determined that NEMA MG 1-
2016's Table 10-5 can apply to all small electric motors subject to
DOE's standards and that most manufacturers already use the breakdown
torque method as a standard practice to determine rated output power.
84 FR 17004, 17016. Accordingly, DOE proposed to define ``rated output
power'' as ``the mechanical output power that corresponds to the small
electric motor's breakdown torque as specified in NEMA MG 1-2016 Table
10-5 for single-phase motors or 140 percent of the breakdown torque
values specified in NEMA MG 1-2016 Table 10-5 for polyphase motors.''
\22\ Id. DOE also proposed defining ``breakdown torque'' as ``the
maximum torque that the motor will develop with rated voltage and
frequency applied without an abrupt drop in speed, determined in
accordance with NEMA MG 1-2016.'' Id. DOE requested comment on the
proposed definitions for ``rated output power'' and ``breakdown
torque.'' Additionally, DOE requested comment on how to determine when
an ``abrupt drop in speed'' (e.g., the local maximum of the torque-
speed plot closest to the rated torque) has occurred when testing the
breakdown torque of a small electric motor. Id.
---------------------------------------------------------------------------
\22\ For purposes of this definition, NEMA MG 1-2016 Table 10-5
can be applied to all small electric motors, regardless of whether
elements of NEMA MG 1-2016 Table 10-5 are identified as for small or
medium motors.
---------------------------------------------------------------------------
In response to the April 2019 NOPR, NEMA commented that there is no
need to define ``breakdown torque'' or ``abrupt drop in speed'' for the
purposes of testing electric motors. (NEMA, No. 84 at p. 3)
Specifically, NEMA stated that incorporating breakdown torque as the
method to define the rated output power of the motor is unnecessary
because NEMA MG 1-2016, Part 1.40 already states the output rating of a
machine ``shall'' consist of the output power. Instead, NEMA
recommended that the declared values of output power be used as
provided on the manufacturer's nameplate and that DOE not require a
declaration of breakdown torque. (NEMA, No. 84 at pp. 3-4). NEMA
further stated that the ``abrupt drop in speed'' corresponds to the
expectations that the motor will slow down or stall if the torque
applied to the motor exceeds the local maximum value of torque that is
most closely located to the rated torque of the motor (i.e., the
breakdown torque). Finally, NEMA claimed that performing any additional
speed-torque tests for determining ``abrupt drop in speed'' would
increase manufacturer burden. (NEMA, No. 84 at pp. 3-5) No other
comments were received in regard to this issue.
In the April 2019 NOPR, DOE did not intend to suggest that it would
require manufacturers to test or report the value of breakdown torque
used to establish the rated output power of a small electric motor.
Rather, the intent of defining ``breakdown torque,'' through reference
to the industry standard NEMA MG 1-2016, was to in turn define ``rated
output power'' for the purpose of measuring average full-load
efficiency. As noted previously, NEMA responded to the April 2019 NOPR
by explaining that NEMA MG 1-2016 Part 1.40 already states the output
rating of a machine shall consist of the output power. (NEMA, No. 84 at
p. 3-4) As indicated by its inclusion in NEMA MG 1-2016, the breakdown
torque method is commonly used by industry for determining rated output
power. Defining rated output power based on NEMA MG 1-2016 provides
additional detail that allows for the accurate comparison of small
electric motors.
Therefore, in this final rule, DOE defines ``rated output power''
as, the mechanical output power that corresponds to the small electric
motor's
[[Page 14]]
breakdown torque as specified in NEMA MG 1-2016 Table 10-5 for single-
phase motors or 140 percent of the breakdown torque values specified in
NEMA MG 1-2016 Table 10-5 for polyphase motors. For purposes of this
definition, NEMA MG 1-2016 Table 10-5 can be applied to all small
electric motors, regardless of whether elements of NEMA MG 1-2016 Table
10-5 are identified as for small or medium motors.
DOE also is defining ``breakdown torque.'' Consistent with the
proposed definition, DOE is defining ``breakdown torque,'' in part, as
``the maximum torque that the motor will develop with rated voltage and
frequency applied without an abrupt drop in speed.'' As previously
noted, the phrase ``abrupt drop in speed'' references the intrinsic
behavior of motors, in which a motor will slow down or stall if the
load applied to the motor exceeds the breakdown torque, and indicates
that minor reductions in speed observed due to measurement
sensitivities are not considered. To provide additional specification
for determining breakdown torque based on the physical attributes of a
small electric motor, DOE is also including in the definition that the
breakdown torque of a motor is the local maximum of the torque-speed
plot of the motor, closest to the synchronous speed of the motor.\23\
---------------------------------------------------------------------------
\23\ The synchronous speed of a motor is calculated as follows:
120 x f / p where f is the frequency at which the motor is operating
and p is the number of poles of the motor.
---------------------------------------------------------------------------
Both the April 2019 NOPR and NEMA's comments explained that on a
torque-speed plot, the breakdown torque is the local maximum torque in
the region of the plot characterized through reference to the rated
torque. The relevant region of the plot can also be characterized
through reference to the synchronous speed. The local maximum of the
torque-speed plot in the region characterized by the rated torque is
the same value as the local maximum of the torque-speed plot in the
region characterized by the synchronous speed. DOE is providing
additional detail to define breakdown torque using the synchronous
speed, as it is a physical attribute of the motor rather than rated
torque, which is a manufacturer declared value.
For the reasons discussed in the preceding paragraphs, DOE is
defining ``breakdown torque'' as the maximum torque that the motor will
develop with rated voltage and frequency applied without an abrupt drop
in speed. The breakdown torque is the local maximum of the torque-speed
plot of the motor, closest to the synchronous speed of the motor,
determined in accordance with NEMA MG 1-2016.
D. Rated Values Specified for Testing Small Electric Motors
DOE notes that the definition of average full-load efficiency at 10
CFR 431.442 specifies that it is determined when the motor operates at
the rated frequency, rated load, and rated voltage. Additionally,
industry standards refer to these rated values, which are expected to
be known or provided (e.g., on the nameplate). However, ``rated
frequency,'' ``rated load,'' and ``rated voltage'' are not defined. To
provide additional specificity regarding these terms, in the April 2019
NOPR, DOE proposed to define them to further ensure the comparability
of results between motors, and to better ensure reproducible testing
for all equipment. 84 FR 17004, 17017-17018. In this final rule, DOE is
amending 10 CFR 431.442 to establish definitions for ``rated
frequency,'' ``rated load,'' and ``rated voltage,'' as discussed in the
following sections.
1. Rated Frequency
The test procedures and energy conservation standards established
under EPCA apply to those regulated motors that are distributed in
commerce within the United States. Within the United States,
electricity is supplied at 60 hertz (``Hz''); in other regions of the
world, electricity is supplied at 50 Hz. Small electric motors could be
designed to operate at frequencies in addition to 60 Hz (e.g., motors
designed to operate at either 60 or 50 Hz). Therefore, it could be
unclear at which frequency the test should be performed. DOE proposed
to amend the small electric motor test procedure at 10 CFR 431.442 by
defining the term ``rated frequency'' as ``60 hertz.'' See 84 FR 17004,
17017.
NEMA commented that explicitly stating that rated frequency is 60
Hz would be beneficial in the case of a motor marked as 60/50 hertz.
(NEMA, No. 84 at p. 4) The CA IOUs supported DOE's proposal that all
tests be performed using a rated frequency of 60 Hz. (CA IOUs, No. 86
at p. 3) The Efficiency Advocates supported DOE's proposal to specify
that all small electric motor tests be performed using a rated
frequency of 60 Hz to remove ambiguity in the test procedure and to
ensure that the test procedure reflects the operating frequency in the
U.S. (Efficiency Advocates, No. 87 at p. 2) DOE did not receive any
comments opposing the proposed definition.
DOE notes that 60 Hz as the tested input frequency matches the
frequency experienced by the motor when installed in the field. In
addition, commenters also recommended DOE require testing at a rated
frequency of 60 Hz, as noted. Therefore, in this final rule, DOE is
amending 10 CFR 431.442 to establish a definition of ``rated
frequency'' as ``60 hertz.''
2. Rated Load
``Rated load'' \24\ is a term used in industry standards to specify
a loading point for motor testing (e.g., sections 5.6 and 6.1 in IEEE
112-2004, and section 8.2.1 in IEEE 114-2010). Typically, a rated load
represents a power output expected from the motor (e.g., a horsepower
value on the nameplate). The rated load will have a corresponding rated
speed and rated torque. In the April 2019 NOPR, DOE proposed to amend
10 CFR 431.442 by defining ``rated load'' as ``the rated output power
of a small electric motor'' (see section III.C for definition of rated
output power). 84 FR 17004, 17017. DOE also proposed that the rated
output power (given on the motor nameplate) be used for any reference
to rated load, full rated load, rated full-load, or full-load in an
industry standard used for testing small electric motors. Id
---------------------------------------------------------------------------
\24\ Also referred to as ``rated full-load,'' ``full rated
load,'' or ``full-load'' interchangeably.
---------------------------------------------------------------------------
The Efficiency Advocates supported DOE's proposed definition for
rated load, commenting that this specification will help ensure that
test procedures are applied consistently. (Efficiency Advocates, No. 87
at p. 2) The CA IOUs supported the definition for ``rated load'' for
small electric motors based on NEMA MG 1-2016. (CA IOUs, No. 86 at p.
3) NEMA commented that qualifying that the rated output power stamped
on the name plate of a small motor is equivalent to rated load, full
rated load, rated full load or full-load in an industry standard is
beneficial and eliminates questions regarding interpretation. (NEMA,
No. 84 at p. 4)
Providing a definition for ``rated load'' further ensures the
comparability of results between motors, and better ensures
reproducible testing. In addition, qualifying that the rated output
power is equivalent to rated load, rated full-load, full rated load, or
full-load in an industry standard used for testing small electric
motors removes any confusion on the interpretation of terms. Commenters
also supported clarifying the term ``rated load.'' Accordingly,
consistent with its proposal, DOE is amending 10 CFR 431.442 to
establish a definition of ``rated load'' as ``the rated output power of
a small electric motor.''
[[Page 15]]
3. Rated Voltage
Industry testing standards use ``rated voltage'' to specify the
voltage supplied to the motor under test (e.g., section 6.1 in IEEE
112-2004, section 6.1 in IEEE 112-2017, and section 3 in IEEE 114-
2010). The industry test procedures incorporated into DOE's regulations
permit manufacturers to select the input voltage for testing. DOE
proposed to continue to permit small electric motors to be tested at
the nameplate voltage \25\ value selected by the manufacturer and to
define ``rated voltage'' at 10 CFR 431.442 as ``the input voltage of a
small electric motor selected by the motor's manufacturer to be used
for testing the motor's efficiency.'' 84 FR 17004, 17017-17018.
---------------------------------------------------------------------------
\25\ The April 2019 NOPR used the term ``nameplate voltage'' but
DOE does not require that a nameplate be affixed to small electric
motors. ``Nameplate voltage'' was used generally to describe
representations made by a manufacturer either on a nameplate affixed
to the unit or in equipment literature provided by the manufacturer.
---------------------------------------------------------------------------
In response to the April 2019 NOPR, the Efficiency Advocates
commented that small electric motors should be tested at all nameplate
voltages \26\ and were concerned that allowing the manufacturer to
select the voltage for testing will result in inconsistent ratings
across products and will allow for gaming of the test procedure because
of the fact that efficiency can vary with input voltage. The Efficiency
Advocates suggested that DOE require that small electric motors be
tested at all nameplate voltages and meet the minimum efficiency
standards at all nameplate voltages. (Efficiency Advocates, No. 87 at
p. 3) The CA IOUs opposed allowing motor manufacturers to select the
voltage to be used when testing small electric motors, asserting that
this creates uncertainty for consumers as to the motor's energy
performance in the field. Instead, they recommended a prescribed
voltage in the test procedure or that the motor be tested at all
voltages listed on the motor nameplate, and that, if the motor is
tested at multiple voltages, an efficiency level for each tested
voltage should be listed on the nameplate. (CA IOUs, No. 86 at p. 3-4)
---------------------------------------------------------------------------
\26\ As discussed previously, DOE does not require that a
nameplate be affixed to small electric motors. DOE understands the
commenter to be referring to representations made by a manufacturer
either on a nameplate affixed to the unit or in equipment literature
provided by the manufacturer. It is in this context that DOE uses
the term ``nameplate'' in this document.
---------------------------------------------------------------------------
In the March 2010 final rule, DOE noted that the industry test
procedures incorporated into DOE's regulations permit manufacturers to
select the input voltage for testing. 75 FR 10874, 10892. In the April
2019 NOPR, DOE proposed to maintain the practice of permitting small
electric motors to be tested at any nameplate voltage value and to
specify this flexibility by defining the term ``rated voltage'' at 10
CFR 431.442 as referring to the input voltage of a small electric motor
selected by the motor's manufacturer to be used for testing the motor's
efficiency. 84 FR 17004, 17081.
DOE is adopting the proposed definition of ``rated voltage'' with
additional clarification. In the April 2019 NOPR, DOE stated that the
proposed definition of ``rated voltage'' would allow small electric
motors to be tested at any nameplate voltage value. Id. As noted, DOE
does not require a nameplate to be affixed to a small electric motor.
To properly describe the voltages from which the voltage is selected
for testing, DOE is specifying that the selected input voltage must be
one of the voltages used by the manufacturer for making representations
of the small electric motor performance (i.e., a represented input
voltage). Specifically, DOE is defining ``rated voltage'' as ``the
input voltage of a small electric motor used when making
representations of the performance characteristics of a given small
electric motor and selected by the motor's manufacturer to be used for
testing the motor's efficiency.'' Based on DOE's experience in
reviewing manufacturer reports and literature, the additional
description reflects manufacturer practice (i.e., small electric motors
are tested at one of the voltages at which manufacturer representations
are made). The additional language also avoids any potential confusion
as to the input voltage required for testing.
DOE is not requiring a specific input voltage for testing. As
discussed in the April 2019 NOPR, NEMA previously indicated that the
input voltage setting can affect efficiency, noting that, if DOE were
to require motors to comply with testing performed at the input voltage
that resulted in the lowest level of efficiency, manufacturers would be
forced to redesign these motors, since at least some motors would be
out of compliance at voltages not currently selected for certification.
84 FR 17004, 17017-17018. In its prior comment, NEMA explained that
these redesign efforts would result in larger motors to accommodate the
additional active material required to create a compliant motor and
could result in the use of larger frame sizes, which would create
utility problems for end users of the motors. (NEMA, EERE-2014-BT-CE-
0019, No. 10 at p. 10) While the selection of the input voltage for
testing may affect the measured efficiency, DOE does not have data to
fully characterize any such impact.
Moreover, EPCA requires that the test procedures shall be
reasonably designed to produce test results which reflect energy
efficiency of small electric motors during a representative average use
cycle and shall not be unduly burdensome to conduct. (42 U.S.C.
6314(a)(1) and (2)) DOE does not have data to indicate that a
represented input voltage selected by a manufacturer is inappropriately
representative of the average use of that small electric motor as
compared to a different represented input voltage. Commenters did not
provide data to indicate that the represented values being selected by
manufacturers are not representative of average use. Therefore, DOE is
maintaining the current test procedure direction allowing manufacturers
to select the input voltage for testing.
E. Effective and Compliance Date
The effective date (i.e., the date the final rule is legally
operative after being published in the Federal Register) for the
adopted test procedure amendments will be 30 days after publication of
this final rule in the Federal Register. See 10 CFR part 430, subpart
C, appendix A, section 12(b) and 10 CFR 431.4 (applying 10 CFR part
430, subpart C, appendix A to commercial/industrial equipment). The
compliance date (the specific date when manufacturers are required to
use the amended test procedures requirements to make representations
concerning the energy efficiency or use of a small electric motor and
electric motor, including certification that the covered equipment
meets an applicable energy conservation standard) is 180 days after the
date of publication of this final rule in the Federal Register. See id.
at section 12(c).
EPCA prescribes that all representations of energy efficiency and
energy use, including those made on marketing materials and product
labels, must be made in accordance with an amended test procedure,
beginning 180 days after publication of the final rule in the Federal
Register. (42 U.S.C. 6314(d)(1)) EPCA also provides an allowance for
individual manufacturers of consumer products to petition DOE for an
extension of the 180-day period if the manufacturer may experience
undue hardship in meeting the deadline. (42 U.S.C. 6314(d)(2)). To
receive such an extension, petitions must be filed with DOE no later
than 60 days before the end of the 180-day period and must detail how
the
[[Page 16]]
manufacturer will experience undue hardship. (Id.)
F. Test Procedure Costs and Impacts
EPCA requires that test procedures prescribed by DOE not be unduly
burdensome to conduct. 42 U.S.C. 6314(a)(2). DOE is amending (1) the
existing test procedure for small electric motors by clarifying the
existing scope and testing instructions, updating the reference to
industry standard IEEE 112 to reference the 2017 version in place of
the 2014 version, and permitting the use of IEC 60034-2-1:2014 as an
additional alternative test procedure; and (2) the existing test
procedure for electric motors by permitting the use of IEC 60034-2-
1:2014 as an additional alternative and equivalent test procedure. DOE
has determined that the test procedures as amended by this final rule
will not be unduly burdensome for manufacturers to conduct and instead
will reduce test burden for manufacturers.
This final rule will result in a net cost savings to manufacturers,
as summarized in Table III-1 and Table III-2.

Further discussion of the analyses of the cost impact of the test
procedure amendments is presented in the following paragraphs.
1. Cost Impacts for Small Electric Motors
The clarifications of the existing scope and test instructions will
not impose any new requirements on manufacturers of regulated small
electric motors. Instead, this final rule will provide manufacturers
with greater certainty in the conduct of the test procedures, offer
additional equivalent testing options, and do not increase test burden.
Reference to IEEE 112-2017 in place of IEEE 112-2004 will not increase
test burden or require new testing. As discussed, results under the
2017 version of IEEE 112 are equivalent to results from testing under
the 2004 version. Manufacturers will be able to rely on data generated
under the current test procedure. Additionally, the incorporation of
IEC 60034-2-1:2014 as an additional alternative test procedure further
harmonizes DOE's test procedures with current industry practice and
international standards. Permitting manufacturers to test according to
IEC 60034-2-1:2014 enables manufacturers who use IEC 60034-2-1:2014 for
business purposes (for international markets), or to comply with
regulatory requirements in other countries, to reduce the number of
tests that they must perform by removing the need to conduct a test
according to the CSA or IEEE methods \27\ currently referenced in DOE's
test procedure for small electric motors. As described in section
III.B.2, NEMA and UL petitioned that certain portions of IEC test
procedure 60034-2-1:2014 be adopted as a permitted alternative test
method for small electric motors and electric motors. UL further noted
in its petition the increasing use of the IEC test procedure 60034-2-
1:2014 by the industry worldwide.
---------------------------------------------------------------------------
\27\ CSA 747-09, CSA 390-10, IEEE 112-2017 (per the amended
reference under this final rule), or IEEE 114-2010 depending on the
category of small electric motor.
---------------------------------------------------------------------------
Recognizing that some, but not all, manufacturers already test
their motors using IEC 60034-2-1:2014, DOE (as explained later in this
section) assumed that 10 percent \28\ of small electric motor models
sold in the U.S. that are tested with either the CSA or IEEE methods
referenced in the Federal test procedure are also tested with the IEC
60034-2-1 method.
---------------------------------------------------------------------------
\28\ NEMA and UL did not provide quantitative information
regarding the number of small electric motors that are tested with
either the CSA method or the IEEE method, and the IEC method,
although NEMA commented that this is an increasing trend. Based on a
review of the market, only a small fraction of motors are designed
for operation on 50 Hz and 60 Hz power (indicating they are suitable
for sale in both the U.S. and foreign markets), or use NEMA and IEC
units of measure (hp vs. kW) and other designators. As noted, the
U.S. electrical grid is operated at 60 Hz, while many other
countries and regions (e.g., Europe) operate at 50 Hz.
---------------------------------------------------------------------------
To calculate the testing cost reduction associated with allowing
the IEC 60034-2-1:2014 method for testing small electric motors, DOE
estimated the number of motor models that would not have to be tested
to both the amended DOE test procedure and the IEC test
[[Page 17]]
method when brought to market. First, DOE reviewed the product catalogs
of four major small electric motor manufacturers published over a
seven-year period.\29\ DOE compared the current product offerings to
the historical catalogs to identify the total number of new models
listed over that period of time.\30\ DOE then annualized that total
number of new models.\31\ Next, DOE scaled up that annualized value
based on the estimated market share of the manufacturers whose catalogs
were reviewed. This scaled-up annualized value estimated the total
number of new models listed for sale each year for the entire U.S.
market.\32\ Then, DOE estimated that 10 percent of new models would be
tested each year.\33\ DOE made this estimate based on (1) knowledge
that many motor models are grouped under a single basic model
classification (and therefore each individual model would not need to
be tested), (2) observations that only a fraction of electric motor
basic models are tested (the remainder have efficiency determined
through an alternative efficiency determination method [``AEDM'']), and
(3) recognition that many motor models may have been relabeled or
rebranded but not redesigned (and therefore no new testing is needed).
Finally, DOE assumed that 10 percent of small electric motor models
sold in the U.S. that are tested with either the CSA or IEEE methods
referenced in the Federal test procedure are also tested with the IEC
60034-2-1 method. Based on these calculations, DOE determined that
approximately 1 new small electric motor basic model per year (i.e., 10
percent of 13) that already would be tested with the IEC 60034-2-1
method would no longer have to conduct an additional test to comply
with DOE's amended test procedure when introduced into the U.S market
and therefore would realize costs savings due to the test procedure
amendments.\34\
---------------------------------------------------------------------------
\29\ The seven-year period for which DOE reviewed product
catalogs was from 2009 to 2016. DOE expects this approach will also
be representative of the market from 2016 to the present. DOE did
not receive comment on this approach following the publication of
the April 2019 NOPR.
\30\ DOE identified 598 small electric motor models introduced
into the U.S. market by these four manufacturers during the period
2009-2016.
\31\ Based on this count, DOE estimates that these four small
electric motor manufacturers collectively introduced approximately
85 small electric motor models into the U.S. market each year.
\32\ This scaled-up calculation yielded a value of 128 small
electric motor models introduced each year for the entire U.S.
market, as DOE assumed these four small electric motor manufacturers
represented approximately 67 percent of the entire U.S. market.
\33\ DOE estimates that approximately 13 new small electric
motor models are tested each year.
\34\ This yields an estimate of 1.28, since DOE estimates 10
percent of the 12.8 new small electric motor models introduced each
year are already tested with the IEC 60034-2-1 method.
---------------------------------------------------------------------------
DOE estimated the cost of testing a single small electric motor
unit to be $2,000 at a third-party facility and approximately $500 at
an in-house facility.\35\ DOE requires at least five units to be tested
per basic model. 10 CFR 431.445(c)(2) To estimate in-house testing
costs, DOE assumed testing a single motor unit requires approximately
nine hours of a mechanical engineer technician time and three hours
from a mechanical engineer. The mean hourly wage for a mechanical
engineer technician is $28.00 and the total hourly compensation paid by
the employer (including all fringe benefits) is $36.25.\36\ The mean
hourly wage for a mechanical engineer is $44.62 and the total hourly
compensation paid by the employer (including all fringe benefits) is
$57.76.\37\ In addition, DOE assumed that 50 percent of tests are
conducted at third-party facilities and 50 percent of tests are
conducted at in-house facilities. Based on these estimates, DOE
anticipates annual cost savings of approximately $8,000 for the small
electric motors industry.

2. Cost Impacts for Electric Motors
Regarding electric motors, DOE is not amending the scope of
applicability of the test procedure at Appendix B. Consistent with the
small electric motors analysis, the incorporation of IEC 60034-2-1:2014
in this test procedure provides manufacturers additional flexibility by
permitting an alternative and equivalent test procedure for measuring
energy loss and would further harmonize DOE's test procedures with
current industry practice and international standards. DOE expects
that, for those manufacturers who are already using IEC 60034-2-1:2014,
this change will reduce the number of tests that manufacturers perform
by avoiding the need to conduct a test according to the CSA or IEEE
methods \38\ currently referenced in DOE's test procedure.
---------------------------------------------------------------------------
\38\ CSA 390-10 or IEEE 112-2017 (per the amended reference
under this final rule) depending on the category of electric motor.
---------------------------------------------------------------------------
To calculate the testing cost reduction associated with allowing
the IEC 60034-2-1:2014 method for testing electric motors, DOE employed
a similar methodology to the small electric motors analysis and
estimated the number of electric motor models that would not have to
test to both the amended DOE test procedure and the IEC test method
when brought to market. First, DOE reviewed the product catalogs of
four major electric motor manufacturers published over a six-year
period.\39\ DOE compared the current product offerings to the
historical catalogs to identify the total number of new models listed
over that period of time.\40\ DOE then annualized that total number of
new models.\41\
---------------------------------------------------------------------------
\39\ The six-year period for which DOE reviewed product catalogs
was from 2010 to 2016. DOE expects this approach will also be
representative of the market from 2016 to the present. DOE did not
receive comment on this approach following the publication of the
April 2019 NOPR.
\40\ DOE identified 8,110 electric motor models introduced into
the U.S. market by these four manufacturers during the period 2010-
2016.
\41\ Based on this count, DOE estimates that these four electric
motor manufacturers collectively introduced approximately 1,352
electric motor models into the U.S. market each year.
---------------------------------------------------------------------------
Next, DOE scaled up that annualized value based on the estimated
market share of the manufacturers whose catalogs were reviewed. This
scaled-up annualized value estimated the total number of new models
listed for sale each year for the entire U.S. market.\42\ Then, DOE
estimated that only 10 percent of new models would be tested each
year.\43\ DOE made this estimate based on (1) knowledge that many motor
models are grouped under a single basic model classification (and
therefore each individual model would not need to be tested), (2)
observations that only a fraction of electric motor basic models are
tested (the remainder have efficiency determined through an AEDM), and
(3) recognition that many motor models that may have been relabeled or
rebranded but not redesigned (and therefore no new
[[Page 18]]
testing is needed). Similar to what was done for small electric motors,
DOE assumed that 10 percent of electric motor models sold in the U.S.
that are tested with either the CSA or IEEE methods referenced in the
Federal test procedure are also tested with the IEC 60034-2-1 method.
Based on these calculations, DOE determined that approximately 20 new
electric motor basic models per year (i.e., 10 percent of 203) that
already would be tested with the IEC 60034-2-1 method would no longer
have to conduct an additional test to comply with DOE's amended test
procedure when introduced into the U.S market and therefore would
realize costs savings due to the test procedure amendments.\44\
---------------------------------------------------------------------------
\42\ This scaled-up calculation yielded a value of 2,028
electric motor models introduced each year for the entire U.S.
market, as DOE assumed these four electric motor manufacturers
represented approximately 67 percent of the entire U.S. market.
\43\ DOE estimates that approximately 203 new electric motor
models are tested each year.
\44\ This yields an estimate of 20.28, since DOE estimates 10
percent of the 202.8 new electric motor models introduced each year
are already tested with the IEC 60034-2-1 method.
---------------------------------------------------------------------------
DOE estimated the cost of testing a single electric motor unit to
be $2,000 at a third-party facility and approximately $500 at an in-
house facility. DOE requires at least five units to be tested per basic
model. 10 CFR 431.17(b)(2) In addition, based on DOE's understanding
that this equipment is tested both in-house and at third-party testing
labs, DOE assumed an even split in testing between the two venues.
Based on these estimates, DOE anticipates annual industry cost savings
of approximately $127,000 for electric motors that are currently
subject to the standards at 10 CFR 431.25.
3. Additional Amendments
The remainder of the amendments adopted in this final rule will not
impact test costs. The other amendments adopted in this final rule
include new definitions for ``rated load,'' ``rated output power,''
``breakdown torque,'' ``rated frequency,'' and ``rated voltage''. The
addition of these definitions will improve test procedure
repeatability. Furthermore, the definitions reflect current industry
practice, and therefore do not impose any new requirements on
manufacturers of regulated small electric motors and electric motors.
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget (``OMB'') has determined that
this test procedure rulemaking does not constitute a ``significant
regulatory action'' under section 3(f) of Executive Order (``E.O.'')
12866, Regulatory Planning and Review, 58 FR 51735 (Oct. 4, 1993).
Accordingly, this action was not subject to review under the Executive
Order by the Office of Information and Regulatory Affairs (``OIRA'') in
OMB.
B. Review Under Executive Orders 13771 and 13777
On January 30, 2017, the President issued E.O. 13771, ``Reducing
Regulation and Controlling Regulatory Costs.'' See 82 FR 9339 (Feb. 3,
2017). E.O. 13771 stated the policy of the executive branch is to be
prudent and financially responsible in the expenditure of funds, from
both public and private sources. E.O. 13771 stated it is essential to
manage the costs associated with the governmental imposition of private
expenditures required to comply with Federal regulations.
Additionally, on February 24, 2017, the President issued E.O.
13777, ``Enforcing the Regulatory Reform Agenda.'' 82 FR 12285 (March
1, 2017). E.O. 13777 required the head of each agency designate an
agency official as its Regulatory Reform Officer (``RRO''). Each RRO
oversees the implementation of regulatory reform initiatives and
policies to ensure that agencies effectively carry out regulatory
reforms, consistent with applicable law. Further, E.O. 13777 requires
the establishment of a regulatory task force at each agency. The
regulatory task force is required to make recommendations to the agency
head regarding the repeal, replacement, or modification of existing
regulations, consistent with applicable law. At a minimum, each
regulatory reform task force must attempt to identify regulations that:
(1) Eliminate jobs, or inhibit job creation;
(2) Are outdated, unnecessary, or ineffective;
(3) Impose costs that exceed benefits;
(4) Create a serious inconsistency or otherwise interfere with
regulatory reform initiatives and policies;
(5) Are inconsistent with the requirements of the Information
Quality Act, or the guidance issued pursuant to that Act, in particular
those regulations that rely in whole or in part on data, information,
or methods that are not publicly available or that are insufficiently
transparent to meet the standard for reproducibility; or
(6) Derive from or implement Executive Orders or other Presidential
directives that have been subsequently rescinded or substantially
modified.
DOE concludes that this rulemaking is consistent with the
directives set forth in these executive orders. This final rule is
estimated to result in a cost savings. The final rule yields annualized
cost savings of approximately $106,000 using a perpetual time horizon
discounted to 2016 at a 7 percent discount rate. Therefore, this final
rule is an E.O. 13771 deregulatory action.
C. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of a final regulatory flexibility analysis (``FRFA'') for
any final rule where the agency was first required by law to publish a
rule for public comment, unless the agency certifies that the rule, if
promulgated, will not have a significant economic impact on a
substantial number of small entities. As required by E.O. 13272,
``Proper Consideration of Small Entities in Agency Rulemaking,'' 67 FR
53461 (Aug. 16, 2002), DOE published procedures and policies on
February 19, 2003 to ensure that the potential impacts of its rules on
small entities are properly considered during the DOE rulemaking
process. 68 FR 7990. DOE has made its procedures and policies available
on the Office of the General Counsel's website: http://energy.gov/gc/office-general-counsel.
These amendments would neither expand the scope of test procedure
applicability to small electric motors beyond those currently subject
to test procedures, nor would it place additional requirements on those
small electric motors currently subject to DOE's test procedures.
Furthermore, this proposal would not place any additional requirements
on those electric motors that are already subject to DOE's test
procedures, nor would it require manufacturers to retest existing
electric motors. Accordingly, manufacturers would not be required under
this rule to retest any existing small electric motors or electric
motors already subject to DOE's test procedures.
These amendments would also not increase testing costs nor would it
impose any additional testing burden on any manufacturers, including
all small businesses. Therefore, DOE concludes that the cost effects
accruing from this rule would not have a ``significant economic impact
on a substantial number of small entities,'' and that the preparation
of a FRFA is not warranted. DOE has submitted a certification and
supporting statement of factual basis to the Chief Counsel for Advocacy
of the Small Business Administration for review under 5 U.S.C. 605(b).
[[Page 19]]
D. Review Under the Paperwork Reduction Act of 1995
Manufacturers of electric motors must certify to DOE that their
equipment comply with any applicable energy conservation standards. To
certify compliance, manufacturers must first obtain test data for their
equipment according to the DOE test procedures, including any
amendments adopted for those test procedures. DOE has established
regulations for the certification and recordkeeping requirements for
all covered consumer products and industrial equipment, including
electric motors. (See generally 10 CFR part 431.) The collection-of-
information requirement for the certification and recordkeeping is
subject to review and approval by OMB under the Paperwork Reduction Act
(``PRA''). This requirement has been approved by OMB under OMB control
number 1910-1400. Public reporting burden for the certification is
estimated to average 35 hours per response, including the time for
reviewing instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing the
collection of information.
Notwithstanding any other provision of the law, no person is
required to respond to, nor shall any person be subject to a penalty
for failure to comply with, a collection of information subject to the
requirements of the PRA, unless that collection of information displays
a currently valid OMB Control Number.
E. Review Under the National Environmental Policy Act of 1969
Pursuant to the National Environmental Policy Act of 1969
(``NEPA''), DOE has analyzed this action in accordance with NEPA and
DOE's NEPA implementing regulations (10 CFR part 1021). DOE has
determined that this rule qualifies for categorical exclusion (``CX'')
under 10 CFR part 1021, subpart D, Appendix A5 because it is an
interpretive rulemaking that does not change the environmental effect
of the rule and meets the requirements for application of a CX. See 10
CFR 1021.410. Therefore, DOE has determined that promulgation of this
rule is not a major Federal action significantly affecting the quality
of the human environment within the meaning of NEPA, and does not
require an environmental assessment or environmental impact statement.
F. Review Under Executive Order 13132
Executive Order 13132, ``Federalism,'' 64 FR 43255 (Aug. 10, 1999),
imposes certain requirements on agencies formulating and implementing
policies or regulations that preempt State law or that have Federalism
implications. The Executive Order requires agencies to examine the
constitutional and statutory authority supporting any action that would
limit the policymaking discretion of the States and to carefully assess
the necessity for such actions. The Executive Order also requires
agencies to have an accountable process to ensure meaningful and timely
input by State and local officials in the development of regulatory
policies that have Federalism implications. On March 14, 2000, DOE
published a statement of policy describing the intergovernmental
consultation process it will follow in the development of such
regulations. 65 FR 13735. DOE examined this final rule and determined
that it will not have a substantial direct effect on the States, on the
relationship between the national government and the States, or on the
distribution of power and responsibilities among the various levels of
government. EPCA governs and prescribes Federal preemption of State
regulations as to energy conservation for the products that are the
subject of this final rule. States can petition DOE for exemption from
such preemption to the extent, and based on criteria, set forth in
EPCA. (42 U.S.C. 6297(d)) No further action is required by E.O. 13132.
G. Review Under Executive Order 12988
Regarding the review of existing regulations and the promulgation
of new regulations, section 3(a) of E.O. 12988, ``Civil Justice
Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal agencies the
general duty to adhere to the following requirements: (1) Eliminate
drafting errors and ambiguity; (2) write regulations to minimize
litigation; (3) provide a clear legal standard for affected conduct
rather than a general standard; and (4) promote simplification and
burden reduction. Section 3(b) of E.O. 12988 specifically requires that
Executive agencies make every reasonable effort to ensure that the
regulation (1) clearly specifies the preemptive effect, if any; (2)
clearly specifies any effect on existing Federal law or regulation; (3)
provides a clear legal standard for affected conduct while promoting
simplification and burden reduction; (4) specifies the retroactive
effect, if any; (5) adequately defines key terms; and (6) addresses
other important issues affecting clarity and general draftsmanship
under any guidelines issued by the Attorney General. Section 3(c) of
E.O. 12988 requires Executive agencies to review regulations in light
of applicable standards in sections 3(a) and 3(b) to determine whether
they are met or it is unreasonable to meet one or more of them. DOE has
completed the required review and determined that, to the extent
permitted by law, this final rule meets the relevant standards of E.O.
12988.
H. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (``UMRA'')
requires each Federal agency to assess the effects of Federal
regulatory actions on State, local, and Tribal governments and the
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531).
For a regulatory action resulting in a rule that may cause the
expenditure by State, local, and Tribal governments, in the aggregate,
or by the private sector of $100 million or more in any one year
(adjusted annually for inflation), section 202 of UMRA requires a
Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy.
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to
develop an effective process to permit timely input by elected officers
of State, local, and Tribal governments on a ``significant
intergovernmental mandate,'' and requires an agency plan for giving
notice and opportunity for timely input to potentially affected small
governments before establishing any requirements that might
significantly or uniquely affect small governments. On March 18, 1997,
DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820; also available
at http://energy.gov/gc/office-general-counsel. DOE examined this final
rule according to UMRA and its statement of policy and determined that
the rule contains neither an intergovernmental mandate, nor a mandate
that may result in the expenditure of $100 million or more in any year,
so these requirements do not apply.
I. Review Under the Treasury and General Government Appropriations Act,
1999
Section 654 of the Treasury and General Government Appropriations
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family
Policymaking Assessment for any rule that may affect family well-being.
This final rule will not have any impact on the autonomy or integrity
of the family as an institution. Accordingly, DOE has concluded that it
is not necessary to
[[Page 20]]
prepare a Family Policymaking Assessment.
J. Review Under Executive Order 12630
DOE has determined, under E.O. 12630, ``Governmental Actions and
Interference with Constitutionally Protected Property Rights'' 53 FR
8859 (March 18, 1988), that this regulation will not result in any
takings that might require compensation under the Fifth Amendment to
the U.S. Constitution.
K. Review Under Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines
established by each agency pursuant to general guidelines issued by
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has
reviewed this final rule under the OMB and DOE guidelines and has
concluded that it is consistent with applicable policies in those
guidelines.
L. Review Under Executive Order 13211
E.O. 13211, ``Actions Concerning Regulations That Significantly
Affect Energy Supply, Distribution, or Use,'' 66 FR 28355 (May 22,
2001), requires Federal agencies to prepare and submit to OMB, a
Statement of Energy Effects for any significant energy action. A
``significant energy action'' is defined as any action by an agency
that promulgated or is expected to lead to promulgation of a final
rule, and that (1) is a significant regulatory action under Executive
Order 12866, or any successor order; and (2) is likely to have a
significant adverse effect on the supply, distribution, or use of
energy; or (3) is designated by the Administrator of OIRA as a
significant energy action. For any significant energy action, the
agency must give a detailed statement of any adverse effects on energy
supply, distribution, or use if the regulation is implemented, and of
reasonable alternatives to the action and their expected benefits on
energy supply, distribution, and use.
This regulatory action is not a significant regulatory action under
E.O. 12866. Moreover, it would not have a significant adverse effect on
the supply, distribution, or use of energy, nor has it been designated
as a significant energy action by the Administrator of OIRA. Therefore,
it is not a significant energy action, and, accordingly, DOE has not
prepared a Statement of Energy Effects.
M. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788;
``FEAA'') Section 32 essentially provides in relevant part that, where
a rule authorizes or requires use of commercial standards, the notice
of rulemaking must inform the public of the use and background of such
standards. In addition, section 32(c) requires DOE to consult with the
Attorney General and the Chairman of the Federal Trade Commission
(``FTC'') concerning the impact of the commercial or industry standards
on competition.
The modifications to the test procedure for small electric motors
and electric motors adopted in this final rule incorporate certain
testing methods contained of the following commercial standards: ``IEC
60034-2-1:2014, Rotating electrical machines--Part 2-1: Standard
methods for determining losses and efficiency from tests (excluding
machines for traction vehicles);'' IEC 60034-1:2010, ``Rotating
electric machines--Part 1: Rating and performance;'' IEC 60051-1:2016,
``Direct acting indicating analogue electrical measuring instruments
and their accessories--Part 1: Definitions and general requirements
common to all parts;'' ``IEEE 112-2017, IEEE Standard Test Procedure
for Polyphase Induction Motors and Generators;'' and NEMA MG 1-2016
Motors and Generators. DOE has evaluated these standards and is unable
to conclude whether they fully comply with the requirements of section
32(b) of the FEAA (i.e., whether they were developed in a manner that
fully provides for public participation, comment, and review.) DOE has
consulted with both the Attorney General and the Chairman of the FTC
about the impact on competition of using the methods contained in these
standards and has received no comments objecting to their use.
N. Congressional Notification
As required by 5 U.S.C. 801, DOE will report to Congress on the
promulgation of this rule before its effective date. The report will
state that it has been determined that the rule is not a ``major rule''
as defined by 5 U.S.C. 804(2).
O. Description of Materials Incorporated by Reference
In this final rule, DOE incorporates by reference standards
published by IEC, IEEE and NEMA. The IEC standard, titled ``IEC 60034-
2-1:2014 Rotating electrical machines--Part 2-1: Standard methods for
determining losses and efficiency from tests (excluding machines for
traction vehicles),'' is an alternative industry standard to those
currently incorporated by reference (IEEE 112-2004, IEEE 114-2010, CSA
C747-09, and CSA C390-10) for measurement of small electric motor
efficiency and electric motor efficiency (See section III.B for more
details).
IEC 60034-2-1:2014 establishes methods of determining efficiencies
from tests and to specify methods of obtaining specific losses. In
addition, DOE incorporates by reference two additional IEC standards,
titled ``IEC 60034-1:2010, Rotating electrical machines--Part 1: Rating
and performance'' and ``IEC 60051-1:2016, Direct acting indicating
analogue measuring instruments and their accessories--Part 1:
Definitions and general requirements common to all parts.'' IEC 60034-
1:2010 and IEC 60051-1:2016 specify test conditions and procedures that
are required for application of the test methods for measurement of
energy efficiency established in IEC 60034-2-1:2014.
The IEEE standard, titled ``IEEE 112-2017, Test Procedure for
Polyphase Induction Motors and Generators'' establishes methods of
measurement for current and frequency for both small electric motors
and electric motors. DOE incorporates IEEE 112-2017 Test Method A and
Test Method B as an update to the industry test methods that are
currently incorporated by reference from IEEE 112-2004 (See section
III.B for more details). Such action will harmonize the permitted test
methods under subparts X (for small electric motors) and B (for
electric motors) of 10 CFR part 431 and align measurement and
instrumentation requirements with industry practice.
The NEMA standard, titled ``NEMA MG 1-2016 Motors and Generators''
establishes industry definitions for breakdown torque of small electric
motors (See section III.C for more details).
In summary, DOE incorporates by reference the following standards:
(1) IEC 60034-2-1:2014, ``Rotating electrical machines--Part 2-1:
Standard methods for determining losses and efficiency from tests
(excluding machines for traction vehicles)''.
[[Page 21]]
(2) IEC 60034-1:2010, ``Rotating electric machines--Part 1: Rating
and performance''.
(3) IEC 60051-1:2016, ``Direct acting indicating analogue
electrical measuring instruments and their accessories--Part 1:
Definitions and general requirements common to all parts''.
(4) IEEE 112-2017, ``IEEE Standard Test Procedure for Polyphase
Induction Motors and Generators''.
(5) NEMA MG 1-2016, ``Motors and Generators''.

follows:
Sec. 431.442 Definitions.
* * * * *
Breakdown torque means the maximum torque that the motor will
develop with rated voltage and frequency applied without an abrupt drop
in speed. The breakdown torque is the local maximum of the torque-speed
plot of the motor, closest to the synchronous speed of the motor,
determined in accordance with NEMA MG 1-2016 (incorporated by
reference, see Sec. 431.443).
* * * * *
Rated frequency means 60 hertz.
Rated load (or full load, full rated load, or rated full load)
means the rated output power of a small electric motor.
Rated output power means the mechanical output power that
corresponds to the small electric motor's breakdown torque as specified
in NEMA MG 1-2016 Table 10-5 (incorporated by reference, see Sec.
431.443) for single-phase motors or 140 percent of the breakdown torque
values specified in NEMA MG 1-2016 Table 10-5 for polyphase motors. For
purposes of this definition, NEMA MG 1-2016 Table 10-5 is applied
regardless of whether elements of NEMA MG 1-2016 Table 10-5 are
identified as for small or medium motors.
Rated voltage means the input voltage of a small electric motor
used when making representations of the performance characteristics of
a given small electric motor and selected by the motor's manufacturer
to be used for testing the motor's efficiency.
