ABSTRACT:
A generator includes a permanent magnet rotor (1) rotatably mounted within a casing, a Randell (claw-tooth) rotor (1A) mounted for rotation in unison with the permanent magnet rotor, an armature coil (5) associated with the permanent magnet rotor and the Randell rotor, and a field coil (16) associated with the Randell rotor. The output power generated by the permanent magnet rotor and the Randell rotor is obtained from the common armature coil. The generator may be suitably applied to aerospace equipment, unmanned flying objects or to unmanned marine cruising objects.
