A counter-rotatable generator (180) includes a generator stator (186) concentric with concentric counter-rotatable radially inner pole and outer magnet rotors (216, 212). The magnet rotor (212) encircles the pole rotor (216) and the pole rotor (216) encircles the generator stator (186). A rotor air gap (130) is disposed between the magnet and pole rotors (212, 216), and a transformer air gap (224) is disposed between the pole rotor (216) and the stator (186). The magnet rotor (212) includes a circular array of magnets (214) having circumferentially alternating north/south and south/north orientations, retained within a magnet retention ring (215), and the magnets (214) are circumferentially separated from each other by non-magnetic material spacers (213). One stator (186) includes an annular hub (272), axial windings (252, 254) around equi-distantly spaced axial poles (256, 258) on the annular hub (272), radial cores (260) extending radially outwardly from and equi-angularly spaced about a pole hub (250) on the annular hub (272) between the first and second axial windings (252, 254), and radial windings (262) around the radial cores (260).
