Note:

  • A simultaneous maximum torque and maximum speed are not recommended.
  • ∆Bar refers to true pressure difference between inlet port and outlet port.
  • Continuous Rating means that the motor may be run continuously at these ratings.
  • Intermittent operation refers to that the motor running time must not exceed 10% per minute under this condition.

*To assure the best orbital motor life, run it for approximately one hour at 30% of rated pressure before application to full load. Be sure this motor is filled with fluid before any load applications.

Tips: Troubleshooting of hydraulic orbital motor

Failures Reasons Solutions
Hydraulic orbital motor temperature is too high Overloaded Load as required
The parts are damaged, especially the stator Replace damaged parts
Excessive noise The hydraulic system has air Exclude the air in the system according to the operation precautions
Overspeed Adjust motor speed
Parts are damaged Replace damaged parts
Oil leakage at the shaft end Damaged or scratched sealing ring Replace the sealing ring
Dirt or water in the input end causes the shaft to rust Remove spline rust
Excessive radial load The radial load shall not exceed the specified value
Excessive back pressure Connect to external drain pipe
Oil leakage on both sides of the stator O ring is damaged Replace the sealing ring
Dirt or burrs on the joint surface Disassemble, clean and deburr
Back cover bolts are not tight Tighten the bolts
Shaft does not rotate Work device stuck Check working device
System problem Check the system
Large radial axial load Check installation
Insufficient torque The oil temperature is too high or the oil viscosity is too low Enhanced cooling
The motor efficiency is reduced due to the wear of the rotor or the small linkage shaft Replace worn parts
