LOW TORQUE RIPPLE SWITCHED RELUCTANCE MOTOR

摘要

A switched reluctance motor includes a stator defining a plurality of radially-inward-extending poles (18) and a rotor defining a plurality of radially-outward-extending poles. The poles (18) of the stator define a shape in radial cross section characterized by a generally rectangular body portion, and a tip portion which tapers at an angle (B) no greater than 40 degrees relative to the sides (32) of the rectangular body portion. The nominal width of the rectangular body portion of each stator pole is at least 1.3 times the nominal (chordal) dimension across the arcuate, radially-innermost surface (20) on the tip portion thereof.
