Abstract
A method for monitoring motor position in a multiple phase switched reluctance motor having phase windings which are energized by a controller involves producing a signal indicative of a current delivered to an active phase winding and producing a signal indicative of a voltage across the active phase winding. A flux linkage associated with the active phase winding is then established based at least in part upon the current indicative signal and the voltage indicative signal. A position of the motor is then estimated based at least in part upon the current indicative signal and the established flux linkage.
