1. An energy transfer apparatus for operating on electrical power comprising:

  • a motor comprising a rotatable stator and a rotatable rotor, the rotor of the motor being supported for rotation about a common central axis with the stator of the motor under the influence of electromagnetic fields developed in the stator of the motor;

    a generator comprising a rotatable stator and a rotatable rotor, the rotor of the generator being supported for rotation about a common central axis with the stator of the generator under the influence of electromagnetic fields developed in the stator of the generator;

    means physically coupling one ofthe stator of the motor to the stator of the generator and the rotor of the motor to the rotor of the generator, andthe stator of the motor to both the stator of the generator, in a direct manner, and to the rotor of the generator, in an inverse rotation manner, and the rotor of the motor to the stator of the generator;

    means for applying power from an external source to the stator of the motor; and

    at least one output shaft coupled to be driven by one of the stator and the rotor of the generator, whereby the output shaft can be driven at speeds in excess of the speed of the motor.
