Abstract:
1. An axial gap dynamo electric machine, the machine comprising: a) an axle, b) a stator disk having at least one electrically energizable planar coil array for generating a Lorenz force disposed co-axially about said axle, c) a rotor disk in rotary co-axle connection to said axle and vertically adjacent said stator disk for being responsive to the energization thereof and having disposed between the outer periphery thereof and the outer half of each radial section of the rotor disk at least two concentric arrays of permanent magnets with each magnet having an alternating orientation of the poles with respect to the adjacent magnets in the same concentric array, and the opposite orientation of the nearest magnetic in the adjacent concentric array, d) a bearing plate having at least two circular arrays of permanent magnets, wherein the circular array of the bearing plate laterally coincide with the circular array of permanent magnets about the outer periphery of said rotor disk to levitate said rotor disk and said axle.
