Abstract: A switched reluctance traction system is provided for work machines. The switched reluctance traction system may include a plurality of switched reluctance motors. Each switched reluctance motor may include a stator with a plurality of stator poles and a rotor with a plurality of rotor poles. The switched reluctance traction system may also include one or more coupling elements to couple together the plurality of switched reluctance motors such that each of the plurality of motors is capable of driving the switched reluctance traction system independently.

Abstract: A system is provided for controlling slip of a ground-engaging traction device of a work machine. The system includes an actual slip calculator operable to transmit an actual slip signal corresponding to an actual slip experienced by the work machine. The system also includes a ground condition selector operable to transmit a ground condition signal corresponding to a selected ground condition. A desired slip calculator is operable to transmit a desired slip signal based on the ground condition signal. A slip controller is coupled with the actual slip calculator and the desired slip calculator. The slip controller is operable to transmit a slip control signal based on the actual slip signal and the desired slip signal. The slip control signal controls the actual slip experienced by the work machine to achieve the desired slip.

Abstract: A method for starting an engine of an electric drive machine may include the method steps of introducing current to an electric motor system from a battery and receiving the current into at least one coil on an electric motor of the electric motor system. The electric motor may be configured to drive the electric drive machine when operating. The method may also include the steps of releasing the energy from the at least one coil to an energy storage device and discharging the voltage from the energy storage device to a power generation system to start the engine. A system for starting an engine of an electric drive machine is also disclosed.
