Axial piston motors are suitable for the following working conditions: high pressure and high power applications, usually with working pressure of 200-400bar and power of more than 500kW. Applications that require precise speed control or position retention, because of its high volumetric efficiency (up to 95%) and good low-speed stability. Variable speed regulation requirements, wide range of stepless speed change can be achieved by adjusting the displacement. Frequent start-stop or reversing conditions, axial piston motors respond quickly and have small reversing shock. Space-constrained high power density requirements, axial piston motors have a low unit power mass. Long life requirements, the design life can reach more than 10,000 hours. Compared with gear motors, axial piston motors are more efficient but more expensive; compared with vane motors, axial piston motors are resistant to high pressure but are more sensitive to pollution. For low-speed and high-torque requirements, radial piston motors may be more suitable.
