Abstract
Abstract A differential motor/generator apparatus comprising a stator region, a first rotating member and a second rotating member. The stator region includes at least one stator component and an opening. The stator member includes at least one pair of torroid regions each having at least one winding positioned thereon in parallel. The first rotating member is associated with the stator region and is positionable within the opening of the stator region. The second rotor member is rotatably associated with the stator region and includes a cavity. A portion of the stator region and the first rotor member are positionable within the cavity of the second rotating member. This enables the first and the second rotating members to rotate about a common axis of rotation.
