Abstract
A hybrid switched reluctance motor is provided that reduces torque ripple. A novel rotor design includes flux barriers. The flux barriers are positioned and shaped to create implicit saliency and reluctance torque for the motor. A gradual change in the motor reluctance results which avoids rapid increases in flux density. The rotor also increases efficiency by reducing acoustical and vibrational responses and associated energy loses.
