Abstract: A permanent magnet alternator employing a mechanically regulated output. The alternator contains a rotor, or a flywheel which houses a plurality of permanent magnets. A rotating magnetic flux field is created by the rotation of the flywheel. A stator assembly, including a plurality of windings or coils is disposed concentrically with the rotor and adjacent to the rotating flux field. The coils produce an electrical output based on their exposure to the rotating flux field. A control assembly is disposed concentrically within the stator assembly. The stator assembly is rotatably coupled to the control assembly and becomes axially displaced relative to the magnetic flux field as a result of rotation relative to the control assembly.
