Abstract

See full text

A method to control the rotor position in a reluctance motor includes: energizing a phase winding to an energized state so as to move a rotor relative to a stator; switching the phase winding between the energized state and a freewheeling state over a pulsing period to produce a plurality of phase current pulses wherein the phase current freewheels in the freewheeling state over a freewheeling period of each current pulse; sampling rates of change of phase current and amplitudes of phase current during a plurality of freewheeling periods; de-energizing the phase winding; and computing the angular position of the rotor.
