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.
