Abstract
A switched reluctance machine has a stator which has an array of alternate wide and narrow poles around its inner circumference. Coils are wound around the wide poles only. The rotor includes segments of soft magnetic material carried on a non-magnetic core. The segments are so proportioned at the air gap that the flux produced by one stator coil passes through two or more segments and returns through the adjacent narrow poles. The machine is capable of producing a high output.
