I. Introduction

    Electric motors are included in the list of ``covered equipment'' 
for which the Department of Energy (``DOE'') is authorized to establish 
and amend energy conservation standards and test procedures. (42 U.S.C. 
6311(1)(A)) DOE's test procedures for electric motors are prescribed at 
Appendix B to Subpart B of 10 CFR part 431 (``Appendix B''). The 
following sections discuss DOE's authority to establish and amend test 
procedures for electric motors, as well as relevant background 
information regarding DOE's consideration of test procedures for this 
equipment.

A. Authority and Background

    The Energy Policy and Conservation Act, as amended (``EPCA''),\1\ 
among other things, authorizes DOE to regulate the energy efficiency of 
a number of consumer products and certain industrial equipment. (42 
U.S.C. 6291-6317) Included within this authority are electric motors, 
the subject of this RFI. (42 U.S.C. 6311(1)(A))
---------------------------------------------------------------------------

    \1\ 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 (October 23, 2018).
---------------------------------------------------------------------------

    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

[[Page 34112]]

procedures. Relevant provisions of EPCA specifically include 
definitions (42 U.S.C. 6311), energy conservation standards (42 U.S.C. 
6313), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 
6315), and the authority to require information and reports from 
manufacturers (42 U.S.C. 6316(a) and 42 U.S.C. 6296).
    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) DOE may, however, grant waivers 
of Federal preemption for particular State laws or regulations, in 
accordance with the procedures and other provisions of EPCA. (42 U.S.C. 
6316(a))
    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 must 
use 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 the criteria and procedures 
DOE must follow when prescribing or amending test procedures for 
covered equipment. EPCA requires that any test procedures prescribed or 
amended under this section must be reasonably designed to produce test 
results which reflect energy efficiency, energy use or estimated annual 
operating cost of a given type 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)) If DOE 
determines that a test procedure amendment is warranted, it must 
publish proposed test procedures and offer the public an opportunity to 
present oral and written comments on them. (42 U.S.C. 6314(b))
    EPCA, pursuant to amendments made by the Energy Policy Act of 1992, 
Public Law 102-486 (October 24, 1992), specifies that the test 
procedures for electric motors subject to standards are those specified 
in National Electrical Manufacturers Association (``NEMA'') Standards 
Publication MG1-1987 and Institute of Electrical and Electronics 
Engineers (``IEEE'') Standard 112 Test Method B, as in effect on 
October 24, 1992. (42 U.S.C. 6314(a)(5)(A)). If these test procedures 
are amended, DOE must amend its test procedures to conform to such 
amended test procedure requirements, unless DOE determines by rule, 
published in the Federal Register and supported by clear and convincing 
evidence, that to do so would not meet the statutory requirements 
related to the test procedure representativeness and burden. (42 U.S.C. 
6314(a)(5)(B)) As noted later in this document, these industry-based 
procedures have been revised a number of times and DOE has amended its 
regulations consistent with these changes.
    EPCA also requires DOE to evaluate its test procedures at least 
once every 7 years for each type of covered equipment, including 
electric motors, to determine whether amended test procedures would 
more accurately or fully comply with the requirements that test 
procedures not be unduly burdensome to conduct but be reasonably 
designed to produce test results reflecting energy efficiency, energy 
use, and estimated operating costs during a representative average use 
cycle of the equipment at issue. (42 U.S.C. 6314(a)(1)) In addition, if 
the Secretary determines that a test procedure amendment is warranted, 
the Secretary must propose amended test procedures (published 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 proposed test procedures. (42 U.S.C. 6314(b)) If 
DOE determines that test procedure revisions are not appropriate, DOE 
must publish its determination not to amend the test procedures. (42 
U.S.C. 6314(a)(1)(A)(ii))
    DOE is publishing this RFI to collect data and information to 
inform its decision in satisfaction of its obligations under EPCA.

B. Rulemaking History

    DOE established test procedures for electric motors that referenced 
NEMA MG1-1993 and IEEE 112-1996. 64 FR 54114 (October 5, 1999) 
(``October 1999 final rule''). The October 1999 final rule also 
incorporated by reference Canadian Standards Association (``CSA'') 
Standard C390-93, Energy Efficiency Test Methods for Three-Phase 
Induction Motors, which DOE found to be a widely recognized alternative 
that was consistent with IEEE 112-1996. Id.
    On May 4, 2012, DOE amended the test procedures for electric motors 
consistent with its obligations under EPCA to incorporate the NEMA MG 
1-2009 and the IEEE 112-2011 into its regulations. 77 FR 26608 (``May 
2012 final rule''). The May 2012 final rule also updated the 
regulations to reference the most current version of CSA C390. Id.
    On December 13, 2013, DOE again amended its electric motor test 
procedure by clarifying the test setup requirements for certain 
electric motors. 78 FR 75962 (``December 2013 final rule''). DOE 
explained that changes brought about by the Energy Independence and 
Security Act of 2007 (Pub. L. 110-140 (December 19, 2007)) and the 
American Energy Manufacturing Technical Corrections Act (Pub. L. 112-
210, Sec. 10 (December 18, 2012)) enabled DOE to consider an expanded 
scope of electric motors for regulatory coverage. Id. at 78 FR 75965. 
DOE determined that the motors covered by the expanded scope could be 
tested using the testing methods provided in IEEE 112 (Test Method B) 
and CSA C390-10 (which were both part of DOE's test procedure 
regulations) to accurately measure their losses and determine their 
energy efficiency. Id. However, some of these motors required 
additional testing set-up instructions prior to testing, which DOE 
established in the December 2013 final rule.\2\ Id.
---------------------------------------------------------------------------

    \2\ A 2011 version of NEMA MG 1 was released prior to the 
publication of the December 2013 final rule. The updates from the 
2009 version, however, did not affect the sections of NEMA MG-1 
incorporated by reference in the DOE regulations. Subsequently, DOE 
declined to incorporate by reference NEMA MG 1-2011. 78 FR 75962, 
75963.
---------------------------------------------------------------------------

    DOE's test procedures for electric motors at 10 CFR part 431, 
subpart B, Appendix B (``Appendix B'') currently incorporate by 
reference NEMA MG 1-2009, IEEE 112-2004 Test Method B, and CSA Standard 
C390-10. Appendix B also includes additional specifications necessary 
for testing certain types of electric motors. 10 CFR part 431, subpart 
B, Appendix B, Sec. 4.
    On March 1, 2017, NEMA published NEMA MG 1-2016, Motors and 
Generators. On February 14, 2018, IEEE published IEEE 112-2017, IEEE 
Standard Test Procedure for Polyphase Induction Motors and Generators. 
DOE subsequently proposed to amend the current test procedure 
regulations for small electric motors and electric motors, which 
included a full review of IEEE 112-2017. 84 FR 17004 (April 23, 2019) 
(``April 2019 NOPR''). The relevant updates to the industry test 
procedures (including NEMA MG 1-2016), in addition to potential 
clarification of definitions and test settings for electric motors, are 
discussed in the following section.

II. Request for Information

    In the following sections, DOE has identified a variety of issues 
on which

[[Page 34113]]

it seeks input on deciding whether amending its test procedures for 
electric motors would (1) more accurately or fully comply with the 
requirements in EPCA that test procedures be reasonably designed to 
produce test results which reflect energy use during a representative 
average use cycle, without being unduly burdensome to conduct (42 
U.S.C. 6314(a)(2)); or (2) reduce testing burden. Specifically, DOE is 
requesting comment on any opportunities to streamline and simplify 
testing requirements for electric motors as well as information to help 
inform DOE's related technical and economic analyses.
    Further, DOE recently issued an RFI to seek more broadly 
information on whether its test procedures are reasonably designed, as 
required by EPCA, to produce results that measure the energy use or 
efficiency of a product during a representative average use cycle or 
period of use. 84 FR 9721 (March 18, 2019). DOE seeks comment on this 
issue as it pertains to the test procedure for electric motors.
    Additionally, DOE welcomes comments on other issues relevant to the 
conduct of this process. In particular, DOE notes that under Executive 
Order 13771, ``Reducing Regulation and Controlling Regulatory Costs,'' 
Executive Branch agencies such as DOE are directed to manage the costs 
associated with the imposition of expenditures required to comply with 
Federal regulations. See 82 FR 9339 (February 3, 2017). Consistent with 
that Executive Order, DOE encourages the public to provide input on 
measures DOE could take to lower the cost of its regulations applicable 
to electric motors consistent with the requirements of EPCA.

A. Scope and Definitions

    The term ``electric motor'' is defined as ``a machine that converts 
electrical power into rotational mechanical power.'' 10 CFR 431.12. 
Manufacturers are required to test those electric motors subject to 
energy conservation standards according to the test procedure in 
Appendix B.\3\ (See generally 42 U.S.C. 6314(a)(5)(A); see also the 
introductory paragraph to 10 CFR part 431, subpart B, Appendix B) 
Currently, energy conservation standards apply to a variety of 
categories of electric motors provided that they meet the criteria 
specified at 10 CFR 431.25(g). These categories of electric motors 
include NEMA Design A motors,\4\ NEMA Design B motors,\5\ NEMA Design C 
motors,\6\ and fire pump electric motors.\7\ See 10 CFR 431.25(h)-(j). 
The detailed criteria specified under 10 CFR 431.25(g) specify that the 
currently regulated motors:
---------------------------------------------------------------------------

    \3\ This RFI does not address small electric motors, which are 
covered separately under 10 CFR part 431, subpart X. A small 
electric motor is ``a NEMA general purpose alternating current 
single-speed induction motor, built in a two-digit frame number 
series in accordance with NEMA Standards Publication MG1-1987, 
including IEC metric equivalent motors.'' 10 CFR 431.442.
    \4\ ``NEMA Design A'' motor means a squirrel-cage motor that: 
(1) Is designed to withstand full-voltage starting and developing 
locked-rotor torque as shown in NEMA MG 1-2009, paragraph 12.38.1 
(incorporated by reference, see Sec.  431.15); (2) Has pull-up 
torque not less than the values shown in NEMA MG 1-2009, paragraph 
12.40.1; (3) Has breakdown torque not less than the values shown in 
NEMA MG 1-2009, paragraph 12.39.1; (4) Has a locked-rotor current 
higher than the values shown in NEMA MG 1-2009, paragraph 12.35.1 
for 60 hertz and NEMA MG 1-2009, paragraph 12.35.2 for 50 hertz; and 
(5) Has a slip at rated load of less than 5 percent for motors with 
fewer than 10 poles. 10 CFR 430.12.
    \5\ ``NEMA Design B motor'' means a squirrel-cage motor that is: 
(1) Designed to withstand full-voltage starting; (2) Develops 
locked-rotor, breakdown, and pull-up torques adequate for general 
application as specified in sections 12.38, 12.39 and 12.40 of NEMA 
MG1-2009 (incorporated by reference, see Sec.  431.15); (3) Draws 
locked-rotor current not to exceed the values shown in section 
12.35.1 for 60 hertz and 12.35.2 for 50 hertz of NEMA MG1-2009; and 
(4) Has a slip at rated load of less than 5 percent for motors with 
fewer than 10 poles. Id.
    \6\ ``NEMA Design C'' motor means a squirrel-cage motor that: 
(1) Is Designed to withstand full-voltage starting and developing 
locked-rotor torque for high-torque applications up to the values 
shown in NEMA MG1-2009, paragraph 12.38.2 (incorporated by 
reference, see Sec.  431.15); (2) Has pull-up torque not less than 
the values shown in NEMA MG1-2009, paragraph 12.40.2; (3) Has 
breakdown torque not less than the values shown in NEMA MG1-2009, 
paragraph 12.39.2; (4) Has a locked-rotor current not to exceed the 
values shown in NEMA MG1-2009, paragraphs 12.35.1 for 60 hertz and 
12.35.2 for 50 hertz; and (5) Has a slip at rated load of less than 
5 percent. Id.
    \7\ ``Fire pump electric motor'' means an electric motor, 
including any IEC-equivalent motor that meets the requirements of 
section 9.5 of NFPA 20. Id.

    (1) Are single-speed, induction motors;
    (2) Are rated for continuous duty (MG 1) operation or for duty 
type S1 (IEC)
    (3) Contain a squirrel-cage (MG 1) or cage (IEC) rotor;
    (4) Operate on polyphase alternating current 60-hertz sinusoidal 
line power;
    (5) Are rated 600 volts or less;
    (6) Have a 2-, 4-, 6-, or 8-pole configuration;
    (7) Are built in a three-digit or four-digit NEMA frame size (or 
IEC metric equivalent), including those designs between two 
consecutive NEMA frame sizes (or IEC metric equivalent), or an 
enclosed 56 NEMA frame size (or IEC metric equivalent);
    (8) Produce at least one horsepower (0.746 kW) but not greater 
than 500 horsepower (373 kW), and
    (9) Meet all of the performance requirements of one of the 
following motor types: A NEMA Design A, B, or C motor or an IEC 
Design N or H motor.

10 CFR 431.25(g).
    DOE exempted certain categories of motors from having to satisfy 
any standards after determining that the referenced industry test 
procedures do not provide a standardized test method for determining 
the energy efficiency of these motor configurations.\8\ 79 FR 30934 
(May 29, 2014); see also, 78 FR 75962, 75974, 75987-75989). The 
currently exempted motor categories are:
---------------------------------------------------------------------------

    \8\ DOE notes that, while these motor configurations are not 
currently subject to any energy conservation standards, they remain 
within the Department's scope of covered equipment.

     Air-over electric motors;
     Component sets of an electric motor;
     Liquid-cooled electric motors;
     Submersible electric motors; and
     Inverter-only electric motors.

10 CFR 431.25(l)
    Definitions for terms related to the Federal test method for 
electric motors are provided at 10 CFR 431.12. A number of these 
definitions incorporate references to specific sections of NEMA MG 1-
2009 to characterize the construction and operation of different 
categories of electric motors. DOE is considering revising these 
definitions to update its current NEMA MG 1 references to the most 
recent edition of that standard, NEMA MG 1-2016. These reference 
updates would align DOE's regulatory definitions with current industry 
practice and the revisions under consideration for the electric motors 
test procedure at Appendix B (see section II.B.1).
    Twelve definitions at 10 CFR 431.12 reference the NEMA MG 1-2009 
standard, of which the following five include references to sections of 
NEMA MG 1 that have not changed between the 2009 and 2016 publications 
of the standard: ``electric motor with encapsulated windings,'' 
``electric motor with moisture resistant windings,'' ``electric motor 
with sealed windings,'' ``general purpose electric motor (subtype I),'' 
and ``general purpose electric motor (subtype II).''
    Conversely, the definitions in 10 CFR 431.12 for ``definite purpose 
motor,'' ``definite purpose electric motor,'' ``general purpose 
electric motor,'' ``NEMA Design A motor,'' ``NEMA Design B motor,'' 
``NEMA Design C motor,'' and ``nominal full-load efficiency'' reference 
provisions of NEMA MG 1 that have changed between the 2009 and 2016 
versions. These changes are discussed in the following paragraphs.
    The definitions for ``definite purpose motor,'' ``definite purpose 
electric motor,'' and ``general purpose electric motor'' at 10 CFR 
431.12 reference

[[Page 34114]]

paragraph 14.3, ``Unusual Service Conditions,'' of NEMA MG 1-2009. 
Paragraph 14.3 of NEMA MG 1 provides a list of service conditions that 
may affect the construction or operation of a motor. The NEMA MG 1-2016 
standard adds two conditions to the NEMA MG 1-2009 standard: ``exposure 
to a coupling mass that is greater than 10% of rotor weight and/or has 
a center of gravity that is beyond the shaft extension'' and ``exposure 
to a coupling or coupling/coupling guard combination which could 
produce a negative pressure at the drive end seal.'' DOE notes that the 
regulatory definition for ``general purpose electric motor'' also 
references paragraph 14.2, ``Usual service conditions,'' of NEMA MG 1-
2009, but unlike paragraph 14.3, section 14.2 remains unchanged in NEMA 
MG 1-2016. Prior to June 1, 2016, DOE's energy conservation standards 
for electric motors differentiated between general purpose electric 
motors (for which standards applied) and definite or special purpose 
electric motors (for which standards did not apply). 10 CFR 431.25(a)-
(d) and (f). For electric motors manufactured on or after June 1, 2016, 
DOE's energy conservation standards no longer differentiated between 
these previous broad categories of general purpose and definite or 
special purpose. Consequently, DOE's standards are now differentiated 
according to the criteria listed at 10 CFR 431.25(g) and NEMA and IEC 
Design categories. 10 CFR 431.25(h)-(i). Therefore, the updates to 
these definitions are not expected to change the applicability of test 
procedures or energy conservation standards for electric motors 
manufactured on or after June 1, 2016.
    The definitions for ``NEMA Design A motor,'' ``NEMA Design B 
motor,'' and ``NEMA Design C motor'' at 10 CFR 431.12 reference tables 
of locked-rotor current in sections 12.35.1 and 12.35.2 of NEMA MG 1-
2009. NEMA MG 1-2016 revises these tables by adding a column for 
``Locked-Rotor kVA Code'' and a footnote regarding a tolerance that may 
be applied to the locked-rotor current values based on the associated 
Locked-Rotor kVA Code.\9\ Section 10.37 of NEMA MG 1-2016 provides the 
applicable range of kVA per horsepower for each locked-rotor kVA code 
that would be used to calculate the locked-rotor current tolerances. 
These definitions also reference other sections in NEMA MG 1-2009, each 
of which remains unchanged in the NEMA MG 1-2016 standard. The addition 
of the column for ``Locked-Rotor kVA Code'' is not expected to impact 
the applicability of test procedures or energy conservation standards 
for electric motors. Further, NEMA MG 1-2016's addition of the footnote 
regarding a tolerance that may be applied to the maximum locked-rotor 
current values is a clarification of the existing tolerance presented 
in section 10.37 of NEMA MG1-2009, which remains unchanged in NEMA MG1-
2016, and would also not impact the scope of electric motors that are 
subject to energy conservation standards and test procedures.
---------------------------------------------------------------------------

    \9\ Locked-Rotor kVA Code is a letter which appears on the 
nameplate of an alternating-current motor to show its range of 
locked-rotor kilo-volt-ampere (kVA) per horsepower. The letter 
designations for locked rotor kVA per horsepower are given in 
Section 10.37 of NEMA MG 1-2016. For example, the letter ``N'' 
corresponds to a range of locked rotor kVA per horsepower between 
11.2 and 12.5.
---------------------------------------------------------------------------

    The definition for ``nominal full-load efficiency'' at 10 CFR 
431.12 references Table 12-10 of NEMA MG 1-2009, which provides a list 
of nominal efficiencies and associated minimum motor efficiencies based 
on a 20 percent loss difference. Table 12-10 in NEMA MG 1-2009 lists 
nominal efficiency ratings ranging from 50.5 to 99.0, while Table 12-10 
in NEMA MG 1-2016 lists nominal efficiency ratings ranging from 34.5 to 
99.0. The nominal efficiency ratings (and associated minimum 
efficiencies) in the range of 50.5 to 99.0 did not change between the 
NEMA MG1-2009 and NEMA MG1-2016 versions of the standard. The nominal 
full-load efficiency requirements specified by the energy conservation 
standards for electric motors at 10 CFR 431.25 are efficiency values 
ranging from 74.0 to 96.2; therefore, the addition of nominal 
efficiency ratings ranging from 34.5 to 50.5 in the NEMA MG 1-2016 
version of Table 12-10 will not impact the applicability of test 
procedures or energy conservation standards for electric motors.
    Issue 1: DOE requests comment on the 2016 updates to NEMA MG 1 that 
relate to the electric motor definitions in 10 CFR 431.12. 
Specifically, DOE requests information on how these revisions would 
impact the applicability of test procedures and energy conservation 
standards for electric motors.
    Issue 2: DOE requests comment on whether any other definitions 
should be modified or added to 10 CFR 431.12 to provide additional 
detail or direction in the application of the test procedure for 
electric motors.
    DOE also notes that IEC standard 60034-12, published on November 
23, 2016, allows the use of a new nomenclature for certain electric 
motors that are already covered by DOE's current standards. As an 
example, IEC Design N and IEC Design H motors that meet a ``premium 
efficiency'' attribute are permitted to be designated with an ``E'' 
(i.e. ``NE'' and ``HE''). The ``premium efficiency'' attribute 
generally aligns with the current DOE standards prescribed at 10 CFR 
431.25. In DOE's view, these ``NE'' and ``HE'' motors are already 
addressed by the definitions and standards that DOE currently has in 
place regarding ``N'' and ``H'' motors. See 10 CFR 431.12 (defining the 
terms ``IEC Design H motor'' and ``IEC Design N motors'') and 10 CFR 
431.25(g)-(i) and (l) (establishing the efficiency standards related to 
Design N and H motors and their applicable scope). This view is also 
held by NEMA, which asserted in separate communications to DOE that 
``E''-designated motors are drop-in replacements for their ``non-E''-
designated counterparts. See Letter from NEMA to DOE (March 26, 2018) 
and Supplemental Letter from NEMA to DOE (August 23, 2019). (Both 
letters have been filed in the docket.) To ensure the accuracy of its 
understanding, DOE is seeking comment as to whether its understanding 
of the new nomenclature is correct.
    Issue 3: DOE requests comment on whether a Design NE or Design HE 
motor is distinguishable in performance (aside from energy efficiency) 
from a Design N or Design H motor, respectively, such that the ``E''-
designated motor merits treatment as a separate motor type. If so, why? 
If not, why not?

B. Test Procedure

1. Updates to Industry Standards
    DOE has reviewed each of the industry standards that are currently 
incorporated by reference as test methods for determining the energy 
efficiency of electric motors. Since publication of the December 2013 
final rule, IEEE 112-2004 and NEMA MG 1-2009 have been revised, and CSA 
C390-10 has been reaffirmed, as listed in Table II-1. The following is 
a review of the relevant revisions to IEEE 112-2004 and NEMA MG 1-2009.

----------------------------------------------------------------------------------------------------------------

a. IEEE 112
    In the April 2019 NOPR DOE proposed to incorporate by reference 
IEEE 112-2017 for both small electric motors and electric motors. 84 FR 
17004. Specifically, for electric motors, DOE has proposed to 
incorporate IEEE 112-2017 Test Method B as an alternative to IEEE 112-
2004 Test Method B, and requested comment on this proposal. 84 FR 
17004, 17011-17012. DOE tentatively determined that this proposal would 
harmonize the permitted test methods under subpart B of 10 CFR part 431 
and align measurement and instrumentation requirements with recent 
industry practice. 84 FR 17004, 17011-17012.
b. NEMA MG 1
    The test procedure for electric motors specified at Appendix B 
requires that efficiency and losses be determined in accordance with 
NEMA MG 1-2009, paragraph 12.58.1, ``Determination of Motor Efficiency 
and Losses.'' The text of paragraph 12.58.1 was modified in the 
subsequent revisions to NEMA MG 1-2009. Notably, paragraph 12.58.1 in 
the 2016 revision of MG 1 specifies an additional industry standard, 
IEC 60034-2-1, for calculating the efficiency of horizontal polyphase 
squirrel-cage motors rated 1 to 500 horsepower. Further discussion on 
IEC 60034-2-1 is provided in the following section II.B.1.c of this 
RFI.
c. IEC 60034-2-1
    In a November 2017 notice, DOE sought comment regarding petitions 
from NEMA and Underwriters Laboratory (``UL'') requesting that DOE 
incorporate IEC 60034-2-1:2014 Method 2-1-1B \10\ as an additional 
alternative test method to those already referenced in DOE's 
regulations for determining the energy efficiency of certain electric 
motors and small electric motors. 82 FR 50844 (November 2, 2017). With 
regard to the electric motors test procedure, NEMA and UL's petition 
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, which are 
currently referenced in Appendix B. (NEMA, Docket EERE-2017-BT-TP-
0047,\11\ No. 28.2 at p.1; UL, Docket EERE-2017-BT-TP-0047, No. 29.1 at 
p.1)
---------------------------------------------------------------------------

    \10\ 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.''
    \11\ Docket EERE-2017-BT-TP-0047 is available at https://www.regulations.gov/docket?D=EERE-2017-BT-TP-0047.
---------------------------------------------------------------------------

    DOE reviewed Method 2-1-1B from the IEC 60034-2-1:2014 standard in 
the April 2019 NOPR and initially concluded that the standard would 
provide comparable energy efficiency results to the current required 
test standards (IEEE 112 and CSA C390). 84 FR 17004, 17013. 
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 requested comment on this proposal. Id.
2. Temperature Rise Measurement Location
    The test method for measuring electric motor nominal full-load 
efficiency prescribed under Appendix B specifies that efficiency and 
losses are determined in accordance with paragraph 12.58.1 of NEMA MG1-
2009, and either CSA C390-10 or IEEE 112-2004 Test Method B. See 10 CFR 
part 431, subpart B, Appendix B, Sec. 2. CSA 390-10 and IEEE 112-2004 
both require the motor to be loaded to the rated full load and operated 
until thermal equilibrium is reached. See CSA C390-10, Sec. 7.1.3 and 
IEEE 112-2004, Sec. 5.8.4.4. This segment of the efficiency test is 
known as the ``heat-run test.''
    Section 7.1.3 of CSA C390-10 provides the test instructions for the 
heat-run test, and states that the temperature used to establish 
thermal equilibrium is determined using the temperature measurement 
devices specified in section 7.1.2 of that standard. Section 7.1.2.2 of 
CSA C390-10 explicitly specifies the permissible locations for 
installing the temperature measurement devices when conducting the 
heat-run test.
    Section 5.8.4.4 of IEEE 112-2004 specifies how to terminate the 
heat-run test. These instructions provide that the motor is operated 
until the temperature rises are constant, but unlike CSA C390-10, IEEE 
112-2004 does not explicitly indicate the locations where these 
temperatures must be measured. Instead, Section 5.8.4.3 of IEEE 112-
2004 provides a list of locations on the motor at which temperature 
measurement devices must be equipped, but does not specify which 
temperature measurement device must be used to establish the condition 
of thermal equilibrium in the heat-run test. The same requirements are 
provided in Section 5.9.4.4 of IEEE 112-2017, the latest version of the 
industry standard.
    Issue 4: DOE requests comment on whether the test instructions in 
IEEE 112-2004 Test Method B and/or IEEE 112-2017 Test Method B provide 
sufficient detail regarding placement of temperature measurement 
devices for establishing thermal equilibrium in the heat-run test. 
Specifically, DOE seeks comment, including comment based on testing 
experience, regarding potential locations for measurement to establish 
thermal equilibrium. DOE is also interested in detailed information on 
any testing burden, including cost, associated with measuring at the 
various locations.
3. Rated Motor Horsepower
    Nominal full-load efficiency, the metric for energy conservation 
standards for electric motors, is defined as a representative value of 
efficiency selected from the ``nominal efficiency'' column of Table 12-
10 of NEMA MG 1-2009, that is not greater than the average full-load 
efficiency of a population of motors of the same design. See 10 CFR 
431.12. ``Average full-load efficiency'' is defined as ``. . . the 
ratio (expressed as a percentage) of the motor's useful power output to 
its total power input when the motor is operated at its full rated 
load, rated voltage, and rated frequency.'' Id. Typically, a rated load 
represents a power output expected from the motor (e.g., a horsepower 
value on the nameplate or a manufacturer declared rated motor 
horsepower). The industry testing standards discussed in section II.B.1 
of this RFI do not provide a method to determine the full rated load of 
the tested unit. Rather, the standards rely on a manufacturer-specified 
output power, which is

[[Page 34116]]

usually listed on a motor's nameplate in terms of horsepower (i.e., the 
rated motor horsepower).
    Rated motor horsepower is generally not an intrinsic, observable 
motor property, and motors are usually capable of operating both above 
and below the rated motor horsepower. 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 at its rated 1 hp. The output power of the motor depends on 
the load and the design of the motor. Therefore, the load point (or 
horsepower) at which the motor must be tested is not an intrinsic 
parameter to the motor, but rather a parameter that must be defined or 
specified. The test's load point (or horsepower) is relevant to 
efficiency testing because the efficiency of an electric motor varies 
according to load.
    While the ``nominal full-load efficiency definition'' relies on the 
definition of ``average full-load efficiency'' (and in turn, ``rated 
load''), DOE regulations do not explicitly address how to determine the 
rated load and rated motor horsepower of an electric motor. 
Accordingly, as part of the test procedure evaluation, DOE is 
considering whether to define the term ``rated motor horsepower'' and 
whether defining the term would provide for more accurate comparisons 
of similarly rated motors from different manufacturers. In addition, 
DOE is considering additional changes to address the relationship 
between the term ``rated motor horsepower'' to ``rated load,'' as 
discussed in section II.B.4.b of this RFI.
    As with a recent proposed amendment to the test procedure for small 
electric motors, DOE is considering defining rated motor horsepower to 
be based on the breakdown torque of an electric motor, which is a 
directly measurable quantity. See 84 FR 17004, 17014-17015. Breakdown 
torque is defined in section 1.50 of NEMA MG 1-2016 as the maximum 
torque that the motor will develop with rated voltage and frequency 
applied without an abrupt drop in speed,\12\ and is typically measured 
in accordance with Section 7, ``Other performance tests,'' of IEEE 
Standard 112-2017.
---------------------------------------------------------------------------

    \12\ 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. Therefore, breakdown torque corresponds to a 
local maximum torque (on a plot of torque versus speed) that is 
nearest to the rated torque. NEMA MG 1-2016 does not quantify what 
would constitute ``an abrupt drop in speed,'' but the phrase 
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.
---------------------------------------------------------------------------

    NEMA MG1-2016 requires that the rated horsepower be established by 
identifying the horsepower that corresponds to the appropriate value of 
breakdown torque, established in section 12.37 and section 12.39 of 
NEMA MG1-2016, for general-purpose polyphase 2-digit frame (e.g. 56-
frame) size electric motors and Design A, B, and C polyphase 3- and 4-
digit frame size electric motors, respectively (e.g. 215). While 
section 12.37 applies to general purpose polyphase 2-digit frame size 
electric motors as written, DOE is considering whether section 12.37 of 
NEMA MG 1-2016 could apply to all 2-digit frame size electric motors 
within the DOE scope (as detailed in section II.A of this RFI) such 
that DOE can define rated motor horsepower based on breakdown torque, 
as defined in NEMA MG 1-2016. DOE would need to consider how rated 
motor horsepower should be determined in the cases of special purpose 
and definite purpose 2-digit frame size electric motors within the DOE 
scope.
    Issue 5: DOE requests comment on how industry currently determines 
rated motor horsepower of an electric motor. Specifically, DOE requests 
comment on whether the methods described in sections 12.37 and 12.39 of 
NEMA MG1-2016 reflect how industry currently determines rated motor 
horsepower of an electric motor.
    Issue 6: DOE requests comment on the whether there is a need to 
define the term ``rated motor horsepower,'' and the feasibility of 
establishing such a definition. DOE requests comment and data regarding 
how rated motor horsepower determined as contemplated in the preceding 
discussion would compare to the rated motor horsepower currently 
declared by manufacturers. Additionally, DOE requests comment on how to 
determine the horsepower of a special or definite purpose motor with 
breakdown torque that is not expressly characterized by Table 10-5 of 
NEMA MG 1-2016. DOE also requests comment on any other method that may 
be used to verify the manufacturer declared horsepower of an electric 
motor. DOE is also interested in detailed information on any test 
burden, including cost, associated with the method as contemplated by 
DOE, or other methods as may be suggested.
4. Rated Values Specified for Testing
    DOE is evaluating whether clarifying several other values used for 
testing electric motors is warranted. As noted previously, the 
definition of average full load efficiency at 10 CFR 431.12 specifies 
that the full load efficiency of a motor is determined when the motor 
operates at the rated frequency, rated load, and rated voltage. 
Additionally, industry standards refer to ``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 in subpart B of 10 CFR part 431. Similar to proposed amendments 
to the test procedure for small electric motors, DOE is considering 
whether additional instruction regarding these terms could improve 
clarity and further ensure all motors of a given specification are 
tested using the same settings. See 84 FR 17004, 17017-17018.
a. Rated Frequency
    ``Rated frequency'' is a term commonly used by industry standards 
developed for testing electric motors (e.g., section 6.1 in IEEE 112-
2004, and section 6.1 in CSA C390-10). The test procedures and energy 
conservation standards established under EPCA apply to motors 
distributed in commerce within the United States. Within the United 
States, electricity is supplied at 60 hertz (``Hz''). However, 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, which is used 
in other parts of the world).
    Some electric motors subject to 10 CFR 431.16 are marketed as 
capable of operating at either of these two frequencies and could 
include in their marketing information data regarding motor performance 
at both frequencies (e.g., 60 and 50 Hz). In this case, it could be 
unclear at which frequency the test should be performed. DOE is 
considering defining the term ``rated frequency'' as 60 Hz to expressly 
specify this test requirement.
b. Rated Load
    The term ``rated load'' \13\ is used in industry standards to 
specify a loading point at which to test a motor (e.g., sections 5.6 
and 6.1 in IEEE 112-2004, and section 6.1 in CSA C390-10). Typically, a 
rated load represents a power output expected from the motor (e.g., a 
horsepower value on the nameplate or a manufacturer declared rated 
motor horsepower). The rated load

[[Page 34117]]

will have a corresponding rated speed and rated torque. DOE is 
considering defining the term ``rated load'' as ``the rated motor 
horsepower of an electric motor'' to clarify this test requirement.
---------------------------------------------------------------------------

    \13\ Also referred to as ``full rated load,'' ``rated full-
load,'' or ``full-load.''
---------------------------------------------------------------------------

c. Rated Voltage
    The term ``rated voltage'' is used in industry standards to specify 
the voltage supplied to the motor under test (e.g., section 6.1 in IEEE 
112-2004, and section 6.1 in CSA C390-10). The test procedures 
referenced in Appendix B require a basic model to be tested at the 
rated voltage, without specifying what to do when a manufacturer 
includes multiple rated voltages on the nameplate and marketing 
materials. DOE is considering specifying the input voltage required for 
testing when motors are rated for use at multiple voltages. Options for 
this specification could include testing only at the lowest rated 
voltage, testing only at the highest rated voltage, or testing at all 
rated voltages. Alternatively, similar to what was proposed for small 
electric motors, DOE is considering allowing manufacturers to test and 
certify motors at any rated voltage, provided that the tested input 
voltage setting is listed on the certification report. See 84 FR 17004, 
17018.
    In addition, DOE has found that some motor nameplates are labeled 
with a voltage rating including a range of values, such as ``208-230/
460 volts,'' or other qualifiers, such as ``230/460V, usable at 208V.'' 
DOE is considering how rated voltage for testing should be determined 
in these cases.
    Issue 7: DOE requests comment on the potential definitions of 
``rated frequency'' and ``rated load'' for electric motors. DOE 
requests comment and data regarding how the discussed definitions would 
impact the current test results. DOE also requests comment on the input 
voltage setting(s) that should be used during testing. Specifically, 
DOE requests test data that demonstrates how motor efficiency varies at 
different input voltage settings.

C. Use of an Amended Test Procedure

    If required only for the evaluation and issuance of updated 
efficiency standards, use of a modified test procedure, were DOE to 
finalize such a change, typically would not be required until the 
implementation date of updated standards. Section 8(c) of appendix A 10 
CFR part 430 subpart C. Moreover, were DOE to initiate a rulemaking to 
establish methodologies used to evaluate proposed energy conservation 
standards, such a rulemaking would be finalized at least 180 days prior 
to publication of a NOPR proposing new or amended energy conservation 
standards. See 10 CFR part 430, appendix A, subpart C, sec. 8(d)-(e).

D. Other Test Procedure Topics

    In addition to the issues identified earlier in this document, DOE 
welcomes comment on any other aspect of the current test procedures for 
electric motors found at 10 CFR part 431, subpart B. As noted earlier, 
DOE recently issued an RFI to seek more information on whether its test 
procedures are reasonably designed to produce results that measure the 
energy use or efficiency of a product during a representative average 
use cycle or period of use. 84 FR 9721 (March 18, 2019).
    Issue 8: DOE seeks comment on whether its test procedures for 
electric motors are reasonably designed, as required by EPCA, to 
produce results that measure the energy use or efficiency of a product 
during a representative average use cycle or period of use.
    Issue 9: DOE requests comments on whether potential amendments 
based on the issues discussed would result in a test procedure that is 
unduly burdensome to conduct, particularly in light of any new products 
on the market that have appeared since the last test procedure update.
    DOE's established practice is to adopt industry standards as DOE 
test procedures unless such methodology would be unduly burdensome to 
conduct or would not produce test results that reflect the energy 
efficiency, energy use, water use (as specified in EPCA) or estimated 
operating costs of that product during a representative average use 
cycle or period of use. Section 8(c) of appendix A 10 CFR part 430 
subpart C. In cases where the industry standard does not meet EPCA 
statutory criteria for test procedures DOE will make modifications 
through the rulemaking process to these standards as the DOE test 
procedure. DOE recognizes that adopting industry standards with 
modifications imposes a burden on industry (i.e., manufacturers face 
increased costs if the DOE modifications require different testing 
equipment or facilities).
    Issue 10: To the extent that potential amendments based on the 
issues discussed in this document would result in a procedure that is, 
in fact, unduly burdensome to conduct, DOE seeks information on whether 
an existing private sector-developed test procedure would be more 
appropriate. DOE requests comment on the benefits and burdens of 
adopting any industry/voluntary consensus-based or other appropriate 
test procedure, without modification.
    Issue 11: Additionally, DOE requests comment on whether the 
existing DOE test procedure limits a manufacturer's ability to provide 
consumers with additional features in the electric motors that they 
purchase. DOE particularly seeks information on how the DOE test 
procedures could be amended to reduce the cost of new or additional 
features and make it more likely that electric motors include such 
features while satisfying EPCA.
    Issue 12: DOE also requests comments on any potential amendments to 
the existing test procedures that would address impacts on 
manufacturers, including small businesses.
    Finally, DOE published an RFI on the emerging smart technology 
appliance and equipment market. 83 FR 46886 (September 17, 2018) 
(``September 2019 RFI''). In that RFI, DOE sought information to better 
understand market trends and issues in the emerging market for 
appliances and commercial equipment that incorporate smart technology. 
DOE's intent in issuing the RFI was to ensure that DOE did not 
inadvertently impede such innovation in fulfilling its statutory 
obligations in setting efficiency standards for covered products and 
equipment.
    Issue 13: DOE seeks, as part of this RFI, comments, data and 
information on the issues presented in the September 2018 RFI as they 
may be applicable to electric motors.

    It is DOE's policy that all comments may be included in the public 
docket, without change and as received, including any personal 
information provided in the comments (except information deemed to be 
exempt from public disclosure).
    DOE considers public participation to be a very important part of 
the process for developing test procedures and energy conservation 
standards. DOE actively encourages the participation and interaction of 
the public during the comment period in each stage of this process. 
Interactions with and between members of the public provide a balanced 
discussion of the issues and assist DOE in the process. Anyone who 
wishes to be added to the DOE mailing list to receive future notices 
and information about this process should contact Appliance and 
Equipment Standards Program staff at (202) 287-1445 or via email at
