The hydraulic motor is a hydraulic actuator system, the liquid pressure will pump energy into mechanical energy provided by its output shaft (torque and speed). High-speed motor gear motor with a small size, light weight, simple structure, technology is good, is not sensitive to the oil pollution, impact resistance and inertia is small. Disadvantages greater torque ripple, low efficiency, starting torque is small (only 60% of the rated torque of --70%) and poor low-speed stability. Variable pump torque, speed, pressure. Three are mutual influence, a parameter change variable pump maintenance, the other two have to change. Must be determined in accordance with the load torque. Then consider finishing variable speed pump, in order to determine the type of motor and then determine the pressure, take a look at the feasibility of the selected motor types. No word had come again, for a motor types. After determining the pressure and speed, we can determine the motor displacement.
