Abstract
A short pitched switched reluctance motor control apparatus comprising a voltage provider comprising a first coupling and a second coupling configured to be coupled to a phase winding of the switched reluctance motor for applying a voltage to drive current in the winding between the first and second coupling is disclosed. The apparatus further comprises a controller configured to apply a first voltage pulse to the first coupling, and to apply a second voltage pulse to the second coupling, wherein the start of the second pulse is delayed with respect to the start of the first pulse, and the end of the first pulse is delayed with respect to the end of the second pulse.
