Abstract
A method and apparatus for operating a switched reluctance motor at high efficiency, without requiring a shaft position sensor, allows dynamic increase of the torque margin as the dwell angle of the phase currents is changed in response to a change in load torque. Average current supplied by the DC link is sensed as a measure of load torque and is used to control the dwell angle.
