Energy Conservation Program: Test Procedure for Electric Motors

This final rule amends the existing scope of the U.S. Department of Energy ("DOE") 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.
