摘要:
Plural-stage form-wound stator pole coil windings for a switched reluctance motor utilize a greater portion of the interpole space than conventional windings, thereby increasing production of magnetic flux. In a two-stage form-wound coil winding, the first stage comprises an inner coil winding which fits directly around a stator pole. The second stage comprises an outer coil winding which fits directly around the first coil winding. All outer coil windings are applied to the stator before inserting the inner coil windings into the outer coil windings and electrically connecting the inner coil windings thereto. Torque production and output voltage are increased, resulting in a highly efficient motor.
