Motor User Guide
To ensure optimal operation of OMM, OMP, OMR, BM3, BM4, and other cycloidal hydraulic motors, it is recommended:
1. Oil Temperature: Normal operating oil temperature is 20°C~60°C, with a maximum system operating temperature of 90°C (should not exceed one hour).
2. Filter and Oil Cleanliness Level: The filter's filtration accuracy is 10-30 microns. It is best to install a magnet at the bottom of the oil tank to prevent metal shavings from entering the system. The solid contamination level of the working oil should not exceed 19/16.
3. Oil Viscosity: The kinematic viscosity at 40°C oil temperature is 42-74 mm²/s. Hydraulic oil can be selected according to actual working and ambient temperatures.
4. Motors can be used in series or in parallel. When used in series or parallel, if the back pressure exceeds 10MPa (speed below 200RPM), an external drain port must be used for pressure relief. It is best to connect the external drain port directly to the oil tank.
5. The output shafts of BMS, BMSY, BMT, BMV, and BMK6 series motors can withstand significant axial and radial loads.
6. The optimal operating condition for the motor should be chosen between 1/3 and 2/3 of the rated condition.
7. To ensure a long service life for the motor, it should first be run at 30% of the rated pressure for about 1 hour when applying load; in any case, ensure the motor is filled with oil before applying load.
