For maximum lifespan, load the motor for one hour at 30% of its rated pressure. Always ensure the motor is completely filled with oil before applying any load.
The kinematic viscosity should be between 42-74mm²/s at 40℃. However, hydraulic oil can be selected based on your actual working environment and ambient temperature.
Yes, they are designed for both. Note that if return port pressure exceeds 10MPa (with speeds under 200rpm), you must implement pressure relief via the leakage port.
We recommend a filtration accuracy of 10-30 microns. To prevent metal particles from entering the system, installing a magnetic block at the bottom of the tank is highly advised.
The output shafts of the BM5, BM6, BM7, BM8, and BM10 series motors are specifically engineered to bear larger axial and radial loads compared to smaller models.
For optimum performance and longevity, the motor should generally operate between 1/3 and 2/3 of its rated operating condition.
