ABSTRACT:
An system for minimizing the output torque ripple effect in a switched reluctance electric motor operating in phase overlap mode positions at least one compensating coil such that, when energized, the magnetic flux of the field created by current flowing through the compensation coil couples and opposes the magnetic flux created in the main winding of compensation coil.
