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.
What does ECM mean? Are all the variable speed blower fan motors ECM, or do I need to specify that? You don't need to specify an ECM motor if you buy a variable speed furnace, as all VS furnaces have ECM motors. There is one ECM motor, the X-13, that is ECM but has fixed (multiple) speeds so cannot ramp the speed. The Goodman GME8 is one example of a furnace with this motor, but I know there are others.
