In one embodiment, the control unit 11 may be integrally integrated with the rear housing 1, or may be a separate module assembled to the rear housing 1.
For a better understanding of the invention, the working principle: under normal conditions, the oil distribution disc 4 has seven oil hole high-low pressure oil cavities in the following states: three high pressure chambers, three low pressure chambers, a transition state chamber (transition from low pressure to high pressure or from high pressure to low pressure, i.e. high pressure or low pressure is possible). The volume change of four closed containing cavities of rotor rotation one circle in stator-rotor pair 6 is its discharge capacity, and the state is in seven oilholes: five high-pressure cavities (the volume changes of the two groups of cavities can be complemented), a low-pressure cavity and a transition state cavity, and the volume changes of two closed cavities in one circle of the rotor rotation are changed into the displacement of the rotor rotation.
When hydraulic oil enters an oil port A or an oil port B of the motor rear shell 1, the hydraulic oil is distributed through the oil distribution disc 4 and enters the stator-rotor pair 6, and the generated rotating speed and torque are transmitted to the output shaft 9 through the linkage shaft 10 to drive a load to work. At this time, the oil distribution disc 4 is in three high-pressure cavities, three low-pressure cavities and a transition cavity, and the motor outputs a certain rotating speed according to the current flow. At this time, the pilot oil port 12 is pressurized, hydraulic oil pushes the control valve core 2 to move, and enters the oil distribution disc 4 through the oil duct of the rear shell 1 and the oil duct of the compensation disc 3, at this time, the state of the oil distribution disc is changed into five high-pressure chambers, one low-pressure chamber and one transition chamber, and at this time, the output rotating speed of the motor is changed.
