An electrical generator has at least one rotating ring of field magnets which produce a circular array of magnetic fields, and a ring of generator output coils which are in the magnetic fields. The field magnets are permanent magnets. The generator output coils are movable in a displacement path toward and away from a null position at which they are exposed to zero net flux from the magnetic fields. Movement of the coils by an actuator varies the amplitude of the voltage induced in these coils by the rotating field magnets. The actuator is energized by a...


[ I claim:] [1.] A permanent magnet generator for providing alternating current which has a selected frequency comprising:a loop assembly and a magnet assembly, one of which is rotatable relative to the other said assembly;said magnet assembly provided with at least one ring of field magnets which are arranged to provide a circular array of magnetic fields which vary in magnitude from one circumferential position to another;said loop assembly provided with at least one ring of electrically conductive output loops which are in said magnetic fields and occ...
