ECM Motors

U.S. MOTORS® brand ECM motors (also called EC motors and BLDC motors), manufactured by Nidec Motor Corporation, offer high efficiency and energy conservation. ECM motors are comprised of a brushless permanent magnet (BPM) motor integrated with an electronic control module. This precisely drives the motor’s permanent magnet rotor which provides more energy-efficient operation.

For more than 20 years, Nidec has been a leader in ECM technologies for a variety of industries including commercial and residential applications in HVAC and the pool and spa markets.
