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