ABSTRACT:
Control system for an electronically commutated motor (ECM). The ECM includes a stationary assembly having a plurality of winding stages adapted to be selectively commutated, and rotatable means associated with the stationary assembly in selective magnetic coupling relation with the winding stages. A digital computer operating under stored program control effects the commutation of the winding stages by selectively supplying power thereto in response to a pattern of control signals leaving at least one of the winding stages unpowered at any one time while the other winding stages are powered.
