As defined in the Code of Federal Regulations (CFR), “electric motor” means a machine that converts electrical power to rotational mechanical power.  The scope of this webpage only includes the subset of electric motors regulated in 10 CFR 431, Subpart B and does not include those small electric motors regulated in 10 CFR 431, Subpart X.  There is also a seperate product website for dedicated-purpose pool pump motors.

Recent and Ongoing Activities

DOE has issued a pre-publication Federal Register notice proposing to amend the existing scope of the DOE test procedures consistent with related industry changes for nomenclature and test procedure developments (i.e., for air-over electric motors, submersible electric motors, electric motors greater than 500 horsepower, electric motors considered small, inverter-only electric motors, and synchronous electric motors); add test procedures, metric, and supporting definitions for additional electric motors covered under the proposed scope; and update references to industry standards to reference current versions. Furthermore, DOE proposes to adopt industry provisions related to the prescribed test conditions to further ensure the comparability of test. In addition, DOE proposes to update certain testing instructions to reduce manufacturer burden. Further, DOE proposes to amend the provisions pertaining to certification testing and determination of represented values for electric motors other than dedicated-purpose pool pump motors, apply these provisions to the additional electric motors proposed for inclusion in the scope of the test procedure, and to move both provisions consistent with the location of other certification requirements for other covered products and equipment. Finally, DOE proposes to add provisions pertaining to certification testing and determination of represented values for dedicated-purpose pool pump motors. DOE is seeking comment from interested parties on the proposal.

  • DOE will accept comments, data, and information regarding this NOPR until 60 days after date of publication in the Federal Register. DOE will send a follow-up e-mail once the notice publishes to announce the closing date of the comment period.

DOE has published a Federal Register notice withdrawing a notice of proposed rulemaking (NOPR) issued on June 24, 2016 that proposed to revise its certification, compliance, and enforcement regulations for electric motors and small electric motors to conform to the enforcement regulations for all other covered products and equipment and to consolidate, to a limited extent, the certification and compliance regulations for electric motors and small electric motors with those for other types of covered products and equipment.

  • The proposed rule that published in the Federal Register on June 24, 2016 at 81 FR 41377 is withdrawn as of October 29, 2021.

DOE has published a Federal Register notice delaying the effective date of a recently published final rule amending the test procedures for small electric motors and electric motors. DOE also seeks comment on any further delay of the effective date, including the impacts of such delay, as well comment on the legal, factual, or policy issues raised by the rule.

  • The effective dates of the final rule published January 4, 2021, at 86 FR 4, and the accompanying correction published January 15, 2021, at 86 FR 3747, are delayed to March 21, 2021.

DOE has published a Federal Register Final Rule pertaining to test procedure for Small Electric Motors and Electric Motors. In this final rule DOE is further harmonizing its test procedures with industry practice by updating a currently incorporated testing standard to reference that standard's latest version, incorporating a new industry testing standard that manufacturers would be permitted to use in addition to those industry standards currently incorporated by reference, and harmonizing certain test conditions with current industry standards to improve the comparability of test results for small electric motors. None of these changes would affect the measured average full-load efficiency of small electric motors or the measured nominal full-load efficiency of electric motors when compared to the current test procedures.

  • The effective date of this rule is February 3, 2021.
  • The final rule changes will be mandatory for product testing starting July 6, 2021.
  • The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register on February 3, 2021.
  • The incorporation by reference of certain other publications listed in this rulemaking was approved by the Director of the Federal Register on June 4, 2012.

DOE has published a Federal Register notice announcing a final determination classifying North Carolina Advanced Energy Corporation as a nationally recognized certification program for electric motors and small electric motors.

  • This final determination is effective July 6, 2020.

DOE has published a Fedetal Register notice initiating a data collection process through a request for information (RFI) soliciting public comment to consider whether to amend DOE's test procedures for electric motors. To inform interested parties and to facilitate this process, this document identifies several issues concerning the current test procedures on which comment is sought and invites public comment on any relevant topic (including those that have not been specifically raised).

DOE has published a Federal Register notice initiating a data collection process through this request for information (RFI), to consider whether to amend DOE’s current energy conservation standards for electric motors. DOE is soliciting information from the public to help determine whether amending the current electric motor standards would produce significant energy savings while being technologically feasible and cost effective. Accordingly, DOE seeks information regarding any technological or market changes since the most recent standards update that would justify a new rulemaking to increase the stringency of the current standards consistent with these factors.

DOE has published a  Federal Register notice that announces an interim determination classifying North Carolina Advanced Energy Corporation as a nationally recognized certification program under DOE's regulations regarding recognition of nationally recognized certification programs and procedures for recognition and withdrawal of recognition of accreditation bodies and certification programs for electric and small electric motors.

Notice of Petition

DOE has publishedFederal Register notice of petition and request for comment pertaining to a petition received from North Carolina Advanced Energy Corporation Efficiency Verification Services seeking classification as a nationally recognized certification program. The petition includes documentation to help substantiate the company’s position that its certification program for electric motors and small electric motors satisfies the evaluation criteria for classification as a nationally recognized certification program.
