Abstract
A method of controlling a switched reluctance motor is disclosed herein. The motor composes a stator carrying a plurality of phase windings and a rotor. The method comprises activating the phase windings in a sequence selected to apply torque to the rotor. Wherein during a cycle of rotation of the rotor the phase windings switch between an active state in which current in the phase winding applies torque to the rotor and an inactive state, applying a voltage to a selected phase winding whilst the selected phase winding is in the inactive state to provide a flux in the selected phase winding: determining the current in the selected phase winding; determining the rotor angle based on the current and the flux, and controlling said activating based on the rotor angle.
