High-pressure oil from the hydraulic pump enters the motor, rotating the rotor (e.g., axial piston or gerotor assembly). A planetary gear reducer then converts high-speed/low-torque output into low-speed/high-torque force, driving the slewing ring’s gear teeth. Cushion valves absorb shock during start/stop, ensuring motion stability.

Key Roles
Precision Control:Responds to joystick input for stepless speed adjustment and accurate positioning.
Power Conversion:Transforms hydraulic energy into mechanical torque to overcome inertia (up to tens of tons).
Safety Assurance:Integrated brakes and relief valves prevent sliding on slopes or overload damage.
