Carrier Information on ICM motor

ECM motors

In short, it's a three phase ac synchronous motor with permanent magnets on the rotor (no coils). Solid state circuitry first rectifies single phase power to DC then converts it variable frequency three phase power to run the motor.

I have one myself that went bad last week. Cost $400 for new one plus $50 shipping. My local dealer didn't have any and couldn't find one. The usual PSC (permanent split capacitor) motors are about 1/4 that much cost.

Motor performs very well though. Mine was only about 6 years old.
