Patent ID: 8723382

Claim:
An electromagnetic motor-generator unit (MGU) comprising: a motor including: a rotatable rotor hub; a plurality of permanent magnets disposed on the rotor hub; a rotatable rotor shaft connected to the rotor hub; a plurality of stator brackets arranged in a ring, wherein each of the stator brackets includes a pair of side walls connected by a base to form a generally U-shaped profile, and wherein each of the side walls and base includes a post around which is wound a respective first, second, and third coil each being selectively energizable via a battery pack; and a first chassis which circumscribes the stator brackets, wherein the base of each stator bracket is connected to an inner wall of the first chassis; and a generator positioned adjacent to and coaxially-aligned with the motor, and including: a plurality of insulating rotor plates each having a plurality of equally spaced and radially-outwardly projecting teeth, wherein a gap is defined between the sides of each of the teeth, and wherein the rotor plates are connected to the rotor shaft to rotate in conjunction with the rotor shaft; a plurality of wedge-shaped permanent magnets stacked within the gaps of the rotor plates and substantially filling the gaps; and a second chassis circumscribing the rotor plates and the wedge-shaped permanent magnets, and having a plurality of coils disposed on an inner face of the chassis; wherein the plurality of coils are connectable to a battery pack to selectively recharge the battery pack when the rotor shaft is rotating.
