ABSTRACT:
A counter-rotatable generator includes a generator stator concentric with concentric counter-rotatable radially inner pole and outer magnet rotors. The magnet rotor encircles the pole rotor and the pole rotor encircles the generator stator. A rotor air gap is disposed between the magnet and pole rotors, and a transformer air gap is disposed between the pole rotor and the stator. The magnet rotor includes a circular array of magnets having circumferentially alternating north/south and south
orth orientations, retained within a magnet retention ring, and the magnets are circumferentially separated from each other by non-magnetic material spacers. One stator includes an annular hub, axial windings around equi-distantly spaced axial poles on the annular hub, radial cores extending radially outwardly from and equi-angularly spaced about a pole hub on the annular hub between the first and second axial windings, and radial windings around the radial cores.
