Abstract

A system and method for recovering energy consisting of a mechanical apparatus having a principal motor and a drive shaft, and a recovery motor having a drive means coupled to the drive shaft of the principal motor, wherein the rotation of the drive means is a function of the rotation of the drive shaft, and wherein the recovery motor is adapted to generate electric energy from the rotational movement of the drive means. The system includes an inverter means for receiving and converting the direct current electric energy from the recovery motor to alternating current electric energy using a rectifier means. The system further includes a switch means for receiving and providing the recovered electric energy to the commercial power source, one or more secondary apparatuses or a combination thereof.

(b) a recovery motor having a drive means coupled to the drive shaft of the principal motor, wherein the rotation of the drive means is a function of the rotation of the drive shaft, and wherein the recovery motor is adapted to generate electric energy from the rotational movement of the drive means.

2. A system as in claim 1, wherein the electric energy generated and recovered by the recovery motor is direct current electric energy.

3. A system as in claim 2, further comprising an inverter means for receiving direct and converting the electric energy from the recovery motor into a useable current using a rectifier means.

4. A system as in claim 1, further comprising a switch means adapted for receiving and providing the alternating current electric energy to commercial power source in a first position and to one or more secondary apparatuses in a second position.

5. A system as in claim 4, wherein the switch means is adapted for receiving and providing the alternating current electric energy to the secondary apparatus and the commercial energy source in a third position.

6. A system as in claim 1, wherein the additional electric energy required to rotatably drive the drive shaft of the principal motor when coupled to the drive means of the recovery motor is less than or equal to the electric energy generated by the recovery motor from the rotational movement of the drive means.

7. A system as in claim 1, further comprising a gauge means for determining when the additional electric energy consumed to rotatably drive the drive shaft of the principal motor exceeds the electric energy generated by the recovery motor from the rotational movement of the drive means.

8. A system as in claim 7, wherein the gauge means is adapted to deactivate the principal motor when the additional electric energy consumed to rotatably drive the drive shaft of the principal motor exceeds the electric energy generated by the recover motor from the rotational movement of the drive means.

9. A system as in claim 1, wherein the recovery motor is a multi-phase, brushless direct current motor.

10. A system as in claim 1, wherein the recovery motor is a single-phase, brushless direct current motor.
