Abstract: A dual rotor switched reluctance machine with a fixed stator and separate input and output rotors on either side of the fixed stator is used to transmit power between a power source such as an gas engine and a mechanical drive unit such as wheels or tracks. A switched reluctance motor configuration, such as a 6/4 motor can be combined with a with a higher pole count switched reluctance generator to allow simultaneous operation of the dual rotor machine as both a generator and a motor. Because the fixed stator has the only set of windings the control electronics are greatly simplified over separate motor-generator configurations.

Abstract: A system is provided for transmitting torque with speed modulation between a motor generator and an engine. The system includes a first shaft, a second shaft, a first reduction gearset, and a second reduction gearset. The first shaft is configured to rotatably connect with the motor generator. The second shaft is configured to rotatably connect with the engine. The first reduction gearset is rotatably supported at least in part on the first shaft. The first reduction gearset is disposed in selective engagement with the first shaft via a first overrunning clutch disposed therebetween. The second reduction gearset is rotatably supported at least in part on the first shaft and at least in part on the second shaft. The second reduction gearset is disposed in selective engagement with the first shaft via a second overrunning clutch disposed therebetween.

Abstract: An electrical induction motor includes a plurality of windings, and a plurality of contactors. Each of the plurality of contactors is configured to be selectively opened or closed in a circuit including the plurality of windings to selectively connect the windings together in a star configuration wherein current flowing through the windings results in the generation of 2N magnetic poles, with N equal to the number of phases of the motor. Each of the plurality of contactors is also configured to be selectively opened or closed in the circuit including the plurality of windings to selectively connect the windings together in a mesh configuration wherein current flowing through the windings results in the generation of two magnetic poles.
