    • 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: How to improve the hydraulic orbital motor speed?

    Increasing the flow rate can increase the speed of the hydraulic orbital motor, but it will more or less affect its service life. As long as it is within its rated power range, there is no problem. If the oil pressure reaches the rated pressure, increasing the speed will exceed the power range it can withstand. But it will damage the life of the cycloid hydraulic motor.

    Increasing the flow rate can only increase the speed limit, like 500 rpm to 900 rpm. It is recommended to change the model of the motor, the cycloid motor flow is increased to a certain extent, the speed will not increase uncontrollably, the internal oil pressure increases, and the internal leakage increases, the efficiency drops directly, or the motor is damaged.
