Abstract
Traditional alternators, that is those non-inductor alternators employed in machines such as automobiles, provide either moving conductors which cut through a stationary magnetic field, or a moving magnetic field which passes over stationary conductors. In conventional inductor alternators, neither the field nor armature rotate. An electromotive force is induced in the output windings by periodic changes in the local reluctance of the magnetic circuit carrying the magnetic flux. The reluctance is governed by the shape of the rotor relative to the stator. By the elimination of the stator housing and of the rotor encompassing stator, this invention provides for the use, as inductor alternator rotors, of components which previously could not function as rotors.
