ABSTRACT:
A system and method of controlling an electronically commutated motor (ECM) driving a blower to maintain the mass flow rate of the blower at a desired value. A microprocessor-based controller unit derives a motor control signal from just two inputs, namely the desired mass flow rate and a speed feedback signal representing the actual shaft speed of the ECM.
