Abstract
A switched reluctance motor having a stator with a plurality of radially oriented stator poles. Windings for three phases are wound about the 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. A rotor is mounted for rotation relative to the stator. The rotor has a wide rotor pole and a narrow rotor pole. The rotor poles are distributed on the rotor wherein a narrow rotor pole is disposed to each side of a wide rotor pole in a direction of rotation. The rotor poles are dimensioned such that the energization of one of the phases causes the wide rotor pole to interact with a first energized stator pole to induce a first torque on the rotor and to produce a first predetermined angular rotation of the rotor, and thereafter causes the narrow rotor pole to interact with a second energized stator pole to induce a second torque on the rotor and to produce a second predetermined angular rotation of the rotor.
