结构特点 
·采用镶柱式定转子设计，具有更高的配油精度及机械效率。 
·双滚动轴承设计,具有更大的侧向承载能力。 
·可靠的轴密封设计，承受背压高，可以串并联使用。 
·正反转换向方便、转速平稳。 
·多种油口、输出轴、法兰等连接形式。  

Characteristic features： 
It adapts the gerolor design, which has a higher distribution accuracy and Mechanical efficiency.
Supported by double ball-bearing, the shaft can carry bigger radial force than BM2 motor.
Credible design for 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.
Best combination of efficiency and economy in medium duty applications.

1.最大工作压力指入口最大压力，额定压力指工作压差。 
2.马达不能同时在最大压力和最高转速下工作。 
3.在断续工作条件下，运行时间每分钟不得超过10%。 
4.推荐用68#抗磨液压油，粘度37-73cSt,清洁度ISO18/13。 
5.最高工作油温80°。 
6.马达全负荷工作前，应在最高工作压力的40%以下磨合1小时。 
7.马达允许最高背压10MPa，但建议不要超过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.
