    Abstract: An electric drive system (26) is provided having first and second output members (34, 36) and a driving shaft (31) having an axis or rotation. A plurality of electric motors (28a, 28b, 28c) are arranged adjacent to the driving shaft. Each motor has an output shaft (29a, 29b, 29c) in driving engagement with and substantially parallel to the driving shaft. A differential steering system (40) is operably disposed between the driving shaft and the first and second output members. The differential steering system includes a first planetary gear assembly (42) operably engaged both between the driving shaft and the first output member and between the driving shaft and the second output member. The first planetary gear assembly has an axis of rotation that substantially aligns with the axis of rotation of the driving shaft. A steering motor (70) is operatively engaged with the differential steering system and operable to simultaneously adjust the relative rotational speed of the first and second output members.

    Abstract: A method is provided for controlling power provided by a drive train system (252) of a work machine (200), which includes an engine (230) that provides engine power to a generator (240) that, in turn, provides generator power to a motor (250). The motor (250) provides ground power to a travel mechanism (255) that enables the work machine (200) to travel across a terrain surface. In one embodiment, the method includes adjusting operation of the motor (250) based on a determined ground speed of the work machine (200). Based on the adjusted motor operations, the operation of the generator (250) is adjusted. Also, the operation of the engine (230) is adjusted such that the engine produces an amount of engine power that meets a load demand corresponding to the adjusted. Also, the operation of the engine (230) is adjusted such that the engine produces an amount of engine power that meets a load demand corresponding to the adjusted operation of the generator (240).
