Description
BMSY series orbital hydraulic motor is an advanced hydraulic motor with end-face flow distribution structure. This series of motors use a column-mounted rotating stator pair, which has the characteristics of high working pressure, high working efficiency, good efficiency retention of the whole machine and long working life. On the basis of standard structure, multi-functional variant design can be carried out according to user requirements. Its characteristics:
• The use of advanced stator parameter design, low starting pressure, high efficiency and good retention.
• High working pressure and large output torque. Tapered roller bearing structure, bearing shaft, radial load capacity is strong, so that the motor can directly drive the working mechanism, the scope of use is expanded.
• Advanced end face flow distribution structure, so that the motor with high precision, wear after the automatic compensation function is strong, to ensure high volumetric efficiency, motor long life, to ensure that the motor speed is stable, smooth load speed characteristics.
• Ability to drive larger loads and higher working pressure levels.

* The rated speed and torque refer to the output value under the rated flow and pressure.
* Continuous value refers to the maximum value that the displacement motor can work continuously.
* The intermittent value refers to the maximum value of the displacement motor working for 6 seconds in 1 minute.
* The peak value refers to the maximum value of the displacement motor working for 0.6 seconds in 1 minute.
