Abstract:
A motion stop control for stopping rotation of a hydrostatic motor when operating as a pump driven by a wheel, comprising an electrically controlled variable displacement pump coupled to said motor, an operator control providing an input signal to indicate a desired amount of rotation of the motor, said operator control input signal adjusting the hydraulic power delivered by the pump to the motor, a sensor for sensing rotation of the wheel driven by the hydrostatic motor, and a controller for receiving the input signal and a signal from the sensor to provide a pressure from the pump sufficient to balance pressure at a work port of the motor generated by the wheel driving the motor to stop the movement of the wheel when the input signal indicates the wheel should stop, wherein the motor is a fixed displacement radial piston motor having a pair of work ports connected to the variable displacement pump.
