ABSTRACT:
An alternator/synchronous motor structure provides varying-reluctance paths for radially directed, unidirectional magnetic fields by means of a unique rotor-stator configuration in which inner- and outer-rotor poles and a rotor pole-connecting means surround one end and the inner- and outer-cylindrical surfaces of a hollow cylindrical stator. At least one of the inner or outer poles includes at least one field concentrator member. Optional excitation field may be provided by a stationary winding requiring no brushes for energizing or by permanent magnetization.
