结构特点 
·采用镶柱式定转子设计，具有更高的配油精度，机械效率更高。 
·采用进口轴密封，能承受高背压。 
·多种法兰，油口，输出轴等连接形式。 
·正反转换向方便、转速平稳。 
·体积小结构紧凑。

Characteristic features： 
It adapts the gerolor design. Has higher efficiency than BM1 motor.
Credible design for shaft seal, which can bear high pressure, and be used in parallel or in series.
Direction of shaft speed can be controlled easily and smoothly.
Best efficiency and economy in medium load applications.

1.断续工作压力指入口工作压力，连续工作压力指工作压差。 
2.马达不应同时在高压力和大转速下工作。 
3.推荐用68#抗磨液压油，粘度37-73cSt，清洁度ISO18/13。 
4.马达在断续工作条件下，运行时间每分钟不得超过10%。 
5.工作油温高80°
6.马达满负荷工作前，应在高工作压力的40%以下磨合1h。 
7.马达允许高背压10MPa，但推荐不要超过5MPa，超过时应接外泄油管。

　　 
Note: 
1. Intermittent means the entrance of 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℃.
5. The maximum allowable back pressure is 10Mpa, but the recommended back pressure should not exceed 5MP, 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 ISO 18/13.
