High Efficient Furnace Blower Motors. Utilizing ECM Technology. ECM (electronic commutated motor) is a brushless DC motor with a permanent magnet rotor and a built in inverter. DC motors are more efficient than AC motors. They are also more expensive.
All ECMs are variable-speed motors. However, not all variable-speed motors are ECMs. ECM blowers include a control circuit that adjusts the blower speed to compensate for increased static pressure (which can occur, for example, when dust builds up on the filter).
