Abstract
A control for establishing a rotating field in a single phase AC induction motor (10) having a rotatable output and first (12) and second (14) sets of mechanically displaced windings which are energized alternately and cyclically by a single phase AC input for establishing the rotating field to effect rotation of the output. The control includes a single phase AC input, first and second solid state switch means, 18, 20, for interconnecting the first and second sets of windings, respectively, of the motor with the AC input. The first and second switch means when conductive apply energy from the input to the first and second sets of windings, respectively, and when non-conductive prevent the application of energy from the input to the first and second set of windings, respectively. A controller (26) is provided responsive to the single phase AC wave form for controlling the conduction of the first and second switch means and rendering each of the switch means alternately and cyclically conductive for discrete time periods during each cycle of the single phase AC wave form on the input.
