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 final rule pertaining to test procedures for electric motors. This final rule amends the existing scope of DOE's test procedures for electric motors consistent with related updates to the relevant industry testing standard (i.e., for air-over electric motors, electric motors greater than 500 horsepower, electric motors considered small, inverter-only electric motors, and synchronous electric motors); adds test procedures, an appropriate metric, and supporting definitions for additional electric motors covered under the amended scope; and updates references to industry standards to reference current versions. Furthermore, DOE is adopting certain industry provisions related to the prescribed test conditions to further ensure the comparability of test results. DOE is also amending provisions pertaining to certification testing and the determination of represented values for electric motors other than dedicated-purpose pool pump motors, and re-locating such provisions consistent with the location of the certification requirements for other covered products and equipment. Finally, DOE is adding provisions pertaining to certification testing and the determination of represented values for dedicated-purpose pool pump motors.

  • The effective date of this rule is 30 days after the Final Rule has been published in the Federal Register.
  • The final rule changes will be mandatory for product testing starting 180 days after the Final Rule has been published in the Federal Register.
  • The incorporation by reference of certain publications listed in the rule is approved by the Director of the Federal Register 30 days after the Final Rule has been published in the Federal Register.
  • The incorporation by reference of certain other publications listed in the rule was approved by the Director as of February 3, 2021.
