Abstract: An electromagnetic motor-generator unit (MGU) includes a motor and a generator. The motor includes permanent magnets disposed on a rotor hub, a rotor shaft connected to the hub, and stator brackets arranged in a ring. Each of the brackets forms a generally U-shaped profile. The side walls and base of each bracket includes a post, around which is wound a coil. A first chassis circumscribes the brackets, with the base of each bracket connected to an inner wall of the first chassis. The generator includes insulating rotor plates each having equally spaced teeth. The plates are connected to the shaft. Wedge-shaped permanent magnets are stacked within gaps of the plates. A second chassis circumscribes the plates and the wedge-shaped permanent magnets, and includes coils disposed on an inner face of the second chassis. The coils are connectable to a battery pack to selectively recharge the battery pack.
