Piston pump advantage
High torque output: Due to the simultaneous action of multiple pistons, the axial piston fixed motor can produce higher torque. This makes it perform well in application scenarios that require greater power, such as the walking mechanism and slewing mechanism in heavy engineering machinery, and can easily drive the movement of large equipment.
Wide speed range: Its speed can be adjusted over a wide range. By changing parameters such as the flow and pressure of the hydraulic oil, different speed outputs from low speed to high speed can be achieved. In some occasions where precise speed control is required, such as the spindle drive of machine tools, the axial piston fixed motor can provide the appropriate speed according to the requirements of the processing technology.
High efficiency: The volumetric efficiency and mechanical efficiency of this motor are relatively high. High volumetric efficiency means that the hydraulic oil is more fully utilized, reducing the energy loss caused by internal leakage; high mechanical efficiency means that less energy is lost in the process of converting hydraulic energy into mechanical energy, thereby improving the energy utilization of the entire system.

Application areas
Engineering machinery: In excavators, loaders, cranes and other equipment, axial piston fixed motors are used to drive the movement of walking devices and working devices (such as dipper arms and booms of excavators). Their high torque and adjustable speed characteristics can meet the working requirements of engineering machinery under different working conditions.
Marine equipment: In the steering system and anchor windlass system of ships, axial piston fixed motors can provide reliable power to ensure the normal operation of ship maneuvers and mooring equipment. It can also maintain good performance in harsh marine environments and adapt to the long-term stable operation of ships.
Industrial automation equipment: In some automated production lines, machine tools and other equipment that require precise control of movement, axial piston fixed motors can be used as power sources. Through advanced hydraulic control systems, high-precision position control and speed control can be achieved to improve product processing quality and production efficiency.
