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
Hydraulic orbital motor temperature is too high	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
Insufficient torque	The motor efficiency is reduced due to the wear of the rotor or the small linkage shaft	Replace worn parts
