Abstract:
A switched reluctance motor, comprising:a stator having a plurality of evenly spaced, radially oriented, like stator poles that define a gap between adjacent stator poles;windings for three phases wound about said stator poles wherein a stator pole of a first phase is disposed circumferentially between a winding and an associated stator pole of a second phase and a winding and an associated stator pole of a third phase; anda rotor element mounted for rotation relative to said stator, said rotor element having two diametrically opposite, outwardly projecting wide rotor poles, and two diametrically opposite, outwardly projecting narrow rotor poles, each of said wide rotor poles having a wide rotor pole face and each of said narrow rotor poles having a narrow rotor pole face, said rotor poles being distributed on said rotor wherein a narrow rotor pole is disposed to each side of a wide rotor pole in a direction of rotation, said rotor poles being dimensioned such that said narrow pole face is approximately equal to a stator pole face and said wide rotor pole face spans at least the pole face of a first stator pole and the gap adjacent said first stator pole.
