ABSTRACT:
A drive for a laundry machine having a means for agitating water and fabrics to launder the fabrics and for spinning the fabrics to effect centrifugal displacement of water from the fabrics. An electronically commutated motor energized from a DC power source for driving the agitating and spinning means includes a stator with a plurality of winding stages adapted to be electronically commutated in a plurality of preselected sequences, and a rotatable assembly is arranged in selective magnetic coupling relation with the winding stages so as to be rotatably driven thereby. The rotatable assembly is rotatably driven in one direction in response to the electronic commutation of at least some of the winding stages in one of the preselected sequences and also in the one direction and another direction opposite thereto in response to the electronic commutation of the winding stages in another of the preselected sequences. Means is provided for driving the agitating and spinning means from the rotatable assembly of the electronically commutated motor.
