Energy Conservation Program: Test Procedures for Electric Motors and Small Electric Motors

On January 5, 2011, the U.S. Department of Energy (DOE) issued a supplemental notice of proposed rulemaking to amend the test procedures for electric motors and small electric motors. That supplemental proposal, along with an earlier proposal from December 22, 2008, form the basis for today's action to amend the current test procedures used to measure the energy efficiency of electric and small electric motors. These changes will be mandatory to demonstrate compliance with the current energy efficiency standards starting 180 days after publication. The final rule clarifies the scope of regulatory coverage for electric motors and ensures the accurate and consistent measurement of electric motor and small electric motor energy efficiency through changes to the current test procedures. These changes also clarify certain regulatory terms and language related to electric motors and small electric motors, clarify the scope of energy conservation standards for electric motors, update references to several industry and testing standards for electric motors, incorporate by reference and update alternative test methods that manufacturers may use when certifying polyphase and single-phase small electric motors as compliant, and specify the determination of efficiency requirements for small electric motors.
