Abstract:
A method for detecting and correcting for a step loss condition. A back electromagnetic force signal is measured and compared to a reference voltage. The motor continues operating and the back electromagnetic force signal is measured again and compared to the reference voltage. If the measured levels of the back emf voltages are less than the reference voltage, a step loss condition has occurred and the stator field is repositioned.
