  • Low torque ripple switched reluctance motor
    Patent number: 5844346
    Abstract: A switched reluctance motor includes a stator defining a plurality of radially-inwardly-extending poles and a rotor defining a plurality of radially-outwardly-extending poles. The poles 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 no greater than 40.degree. relative to the sides 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 on the tip portion thereof.
