Abstract

A switched reluctance motor driven by a two-phase source, includes a stator having an even number of evenly-spaced, like stator poles defining a gap between each stator pole; windings for each of the two phases of the motor wound about stator poles that are circumferentially separated by a winding and an associated stator pole of a different phase; and a rotor mounted for rotation relative to the stator, the rotor having an even number of rotor poles, the rotor poles being dimensioned such that when the phases are alternately energized, the rotor poles operatively interact with the stator poles such that the motor advances sequentially to a first state wherein one-third of the rotor poles are magnetically coupled to a like number of the stator poles, to a second state wherein two-thirds of the rotor poles are magnetically coupled to a like number of stator poles and to a third state wherein all of the rotor poles are magnetically coupled to a like number of stator poles.
