Abstract
A switched reluctance motor, comprising: a stator formed from a magnetically permeable material, having "n" number of evenly spaced, radially oriented, like stator poles, the stator poles having like stator pole faces and forming a uniform gap between adjacent stator poles; windings for two phases wound about stator poles that are circumferentially separated by a winding and an associated stator pole of a different phase; a rotor mounted for rotation relative to the stator about an axis, the rotor having at least two rotor sections, a first of the at least two rotor sections including at least 1/4 "n" number of like, wide rotor poles, each having a like, wide rotor pole face, and a second of the at least two rotor sections including at least 1/4 "n" number of like, narrow rotor poles, each having a like, narrow rotor pole face, the rotor having: PA1 a first angular position wherein a first portion of the wide rotor pole faces of the first rotor section are in alignment with a first pair of opposite, energized stator poles and the narrow rotor pole faces of the second rotor section are in alignment with gaps adjacent the first pair of energized stator poles, and PA1 a second angular…
