ABSTRACT:
A drive assembly including an electric motor and frequency variable generator for use with a multi-axle vehicle. The vehicle generally includes an engine driving a first axle and a drive assembly with an electric motor driving a second drive axle. The drive assembly includes a frequency variable generator with an input shaft driven by the engine and the electric motor electrically communicates with the generator to receive output power from the generator. Other details of selected embodiments of the invention include the frequency variable generator having a rotor coupled to rotate with the engine output shaft and a stator electrically connected to the electric motor. An inverter is electrically connected to an electrical power source, such as a battery or the frequency variable generator, as well as to the rotor. A controller communicates with the inverter and is configured to control the magnitude and frequency of the power communicated from the inverter to the rotor winding.
