ABSTRACT:
A switched reluctance machine comprises a stator and a rotor and a winding for each phase of the stator. A single current sensor is arranged to sense current in the phase windings such that they are discriminated between according to the energization sequence of the windings by a controller, including a digital processor which counts the sensed currents and attributes the source of the currents counted among the phase windings according to a known phase winding energization sequence.
