ABSTRACT:
A closed loop control system for variable reluctance stepper motors which senses a voltage indicative of motion on the driven windings, uses this voltage to confirm that motion has occurred, compares this voltage with one modeled after a waveform indicative of no motion and effects successive changes in the winding drive states at optimum times.
