Patent ID: 7687956

Claim:
A motor drive system, comprising: a torque converter for receiving a rotational motion from a source and producing a rotational output, the torque converter having a first body rotatable about a first axis, a plurality of first magnets mounted to the first body, a second body rotatable about a second axis, a plurality of second magnets mounted to the second body, and a plurality of third magnets mounted to the first body, each of the third magnets being located between a corresponding pair of the first magnets; a generator system coupled to the rotational output of the torque converter and producing at least one electrical output; at least one motor drive coupled to an electrical output of the generator system; and an output system coupled to the motor drive, wherein the first magnets are magnetically coupled to the second magnets, and the second body rotates as a result of the magnetic coupling and produces the rotational output.
