Abstract:
A mobile machine may include one or more generator units, a plurality of electric propulsion motors, and a power-transfer system operable to transfer electricity from one or more of the generator units to one or more of the electric propulsion motors. The mobile machine may also include power-system controls that control the connection of the one or more electric propulsion motors to the power-transfer system. The power-system controls may selectively use a first motor-connection strategy for controlling when one or more groups of the electric propulsion motors are connected to the power-transfer system in series, and the power-system controls may selectively use a second motor-connection strategy for controlling when one or more groups of the electric propulsion motors are connected to the power-transfer system in series.
