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.

An inductor alternator for generating power where the environment militates against existing alternators having rotors encased within their stators comprising (a) a rotor of large radius relative to corresponding existing encased rotors but having a correspondingly higher peripheral speed for a given rotational speed, the rotor having a plurality of spaced rotor teeth which on rotor rotation inscribe a circle or annulus, (b) a stator facing only a sector of the rotor rather than enclosing said rotor, the stator being in the form of a segment disposed adjacent the rotor, engaging at any one time only an arc of said inscribed circle or annulus, (c) stationary field coils so disposed within the stator to produce a magnetic flux forming a magnetic circuit through said stator segment and rotor, with the main flux path passing through the rotor teeth in said arc of the inscribed circle or annulus, and (d) output windings disposed within the stator near a stator face where flux density changes are greatest, the output windings being adapted to carry out current induced therein by flux variations resulting from movement of the rotor teeth through the stator.
