[0002] The hydraulic motor is an actuator of the hydraulic system, which converts the provided liquid pressure energy into the mechanical energy (torque and speed) of its output shaft. Liquid is the medium for transmitting force and motion. After the hydraulic motor is manufactured, it is necessary to test its service life under industrial control conditions such as the specified speed. For this purpose, a test bench is required to test the hydraulic motor. Generally, the hydraulic motor is installed on the test bench manually, and the position of the hydraulic motor on the test bench is moved manually.
