Abstract
Described is a hybrid permanent magnet and wire wound starter generator system. The system includes a polyphase stator that converts a rotating magnetic field to electrical energy. The system also includes a rotor including a plurality of permanent magnets and a wound rotor section. The plurality of permanent magnets and the wound rotor section each generate a portion of the rotating magnetic field. Further, the system includes a controller that controls a polarity of the wound rotor section by transitioning the wound rotor section between a magnetic flux enhancement mode and a magnetic flux weakening mode.
