Main Functions
Energy Conversion: Converts the pressure energy of high-pressure hydraulic fluid in the hydraulic system into mechanical energy (torque and speed) of the output shaft, driving the rotation of the load.
Rotational Drive: As a key component of the hydraulic transmission system, it directly drives devices that require rotational power, such as excavator turntables, ship rudders, construction machinery walking mechanisms, and injection molding machine screws.
Supports Stepless Speed and Wide Speed Range: By adjusting the flow of the input fluid, the output speed can be smoothly and continuously controlled to achieve stepless speed regulation, making it especially suitable for applications that require precise speed control.
Provides High Torque Output: Particularly under low-speed conditions, hydraulic motors can deliver extremely high torque (up to several thousand or tens of thousands of N·m) and can directly drive heavy loads without a reducer, making them widely used in scenarios requiring "low speed and high torque."
Excellent Overload and Braking Capability: The hydraulic system itself has overload protection characteristics. When the load is too high, system pressure rises and the motor can be protected through components such as relief valves. Additionally, rapid and reliable braking can be achieved by dedicated braking circuits (such as normally closed brakes or accumulator brakes).
