BM1 Series low speed high torque motors
Description and Features
M1 series motors are small volume spool valve orbit motor with the following features:
- Advanced design of spool valve and stator&rotor, small size and compact structure.
- Credible design of shaft seal, which can bear high pressure and be used in parallel or in series.
- Direction of shaft rotation and speed can be controlled easily and smoothly.
- High efficiency and economical, suitable for medium duty applications.
- A variety of connection types of flange, output shaft and oil port.

Note:
1. Intermittent means the entrance of the maximum pressure; continuous working pressure means the differential pressure.
2. Motor should not work under the highest pressure and the maximum speed.
3. The running time should not exceed 10% under intermittent working conditions.
4. The Maximum working temperature is 80 °C.
5. The maximum allowable back pressure is 10MPa, but the recommended back pressure should not exceed 5MPa.a leaking pipes is needed when exceeding.
6. one hour running time under 40% of maximum working pressure is recommended before full capacity working.
7. Recommending N68 anti-wear hydraulic oil, viscosity 37-73cSt, cleanliness ISO18/13.
