ABSTRACT:
The invention comprises a switched reluctance machine including a stator and a rotor wherein the stator includes stator teeth wound with separately excitable phase windings. The separately excitable phase windings receiving a combination of signals wherein the first of those signals is a phase winding signal and the second of those signals is a magnetic bearing signal. A method of controlling a switched reluctance machine wherein the switched reluctance machine includes separately excitable stator windings. The method comprising the steps of exciting each stator winding with a signal representative of the phase excitation for that winding and superimposing on each of said windings a signal capable of producing the magnetic force necessary to support the rotor in the absence of a mechanical bearing.
