    Note:

    • A simultaneous maximum torque and maximum speed is 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 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 prior to 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 low Enhanced cooling
    The motor efficiency is reduced due to the wear of the rotor or the small linkage shaft Replace worn parts
