Nhm Low Speed Hydraulic Motor BMM Series

Product Application:

BMM micro high speed hydraulic motor is widely used in various construction machinery, agricultural machinery, transportation, machine manufacturing and other departments, such as hydraulic press, conveyor, manipulator, injection molding machine, harvester, tubing pliers, manipulator, lifting crane and other mechanical equipment.

  Characteristic Features:
  • Compact structure, light weight, high efficiency, high speed
  • The shaft seal has high pressure and can be used in series or parallel
  • Advanced structure design, high power density
  In order to make the BM1, BM2, BM3, BM4, BM5, BM6, BM7, BM8, BM9, BMM orbit hydraulic motors work in the best condition, we recommend:
  1. Oil temperature: Normal working oil temperature 20℃-60℃, Maximum system operating temperature 90 ℃, (not more than one hour)
  2. Filter and oil cleanliness: filter filtration accuracy is 10-30 microns, it is best to install a magnetic block at the bottom of the tank to prevent metal particles from entering the system. Working oil and solid pollution level must not be higher than 19/16
  3. Oil viscosity: the kinematic viscosity is 42-74mm²/s when the temperature is 40 ℃. Hydraulic oil can be selected according to the actual work and the ambient temperature.
  4. The motors can be used in series connection or parallel connection, when oil return port pressure is more than 10MPa (rotate speed is smaller than 200rpm), pressure relief must be done with the leakage port, it is best to connect the leakage port directly with the tank.
  5. The output shaft of BM5, BM6, BM7, BM8 and BM10 series motors can bear larger axial and radial loads.
  6. The optimum operating condition of the motor shall be 1/3 to 2/3 of the rated operating condition.
  7. For the maximum life of the motor, load the motor for one hour at 30% of the rated pressure. In any case, make sure the motor is filled with oil before loading the motor.
