Abstract: A power disk alternator includes a rotor of circular cross-section arranged to rotate about an axis having at least two disks facing each other and defining at least one gap therebetween, and a shaft connected to an external source for driving the shaft in rotation about the axis. Each disk has a circular array of arcuately-spaced magnetized elements located adjacent to its periphery, each of the magnetized elements having surfaces of opposite polarity and being disposed side-by-side in a like polarity configuration. Magnetized elements of one disk face magnetized elements of the other disk of opposite polarity, creating magnetic fields between the opposite polarities in the gap between the two disks. The alternator also includes a stator comprising at least one fixed nonmetallic disk having a conductor path comprising at least one uninterrupted conductor on at least one surface thereof, each stator being located in one of the at least one air gap.
