Abstract:
1. A retro-fitable motor-generator device, installed on a pre-existing wheel-assembly of a motor vehicle, said wheel assembly comprising a wheel spindle, a non-movable hub plate, a wheel hub with a plurality of stud-bolts for affixing a tire to the wheel hub, and a braking assembly, said motor-generator device comprising: one or more rotors, each rotor comprising a rotor plate and an rotor cage attached to the periphery of the rotor plate, extending in one direction from the periphery of the rotor plate at approximately a right angle to the rotor plate, forming an essentially bowl or basket shape with a rim, with a plurality of rotor magnets positioned along the rim of the rotor cage, wherein the rotor is attached to the wheel hub by means of the stud-bolts and extends over the wheel hub without modification of the pre-existing wheel hub and rotates with rotation of the wheel hub; and one or more stators, each stator comprising a stator plate and a stator ring affixed to the periphery of the stator plate, with a plurality of stator magnets positioned along the stator ring, wherein the stator plate is rigidly attached to the hub plate and does not interfere or require modification of the pre-existing braking assembly; wherein the plurality of stator magnets are in close proximity to the rotor magnets, the interaction of the moving rotor magnets with the stationary stator magnets can function as a motor providing electric traction or as a generator producing electric power.
