BMS Cycloid Motor
Advanced stator and rotor parameters design, with low starting pressure, high efficiency and stable low speed operation.
- Product Introduction
ZMS Series
Structure Features
◎ Advanced stator and rotor parameters design, with low starting pressure, high efficiency and stable low speed operation;
◎ High operating pressure and high output torque;
◎ Advanced shaft seal design, with high back pressure bearing capacity;
◎ Advanced and reliable linkage shaft design, with a long motor service life;
◎ Advanced oil distribution mechanism design, with high oil distribution accuracy and automatic wear compensation;
◎ The motors can be used in series and parallel; when they are connected in series, they should be connected to the external drain pipe;
◎ Tapered roller bearing support design, with a large radial load carrying capacity, so that the motor can be used directly drive the operating mechanism.

Max. allowable back pressure |

|||||||||
◎ The intermittent operating pressure refers to the Max. allowable operating pressure at the motor inlet port, and the continuous operating pressure refers to the pressure difference between the inlet port and the return port.
◎ Do not operate the motor at the Max. speed and the Max. pressure at the same time.
◎ The motor operating time per minute must not exceed 10% under intermittent operating conditions.
◎ Recommended oil: anti-wear hydraulic oil; Viscosity: 37-73cst; Oil cleanliness: IS018/13; Max. operating oil temperature: 80 ℃.
◎ With special dynamic seal design, the Max. allowable back pressure of the motor can be up to 10MPa; however, in order to obtain the good service life and comprehensive mechanical performances, the back pressure should not exceed 5MPa. If it is exceeded, it is recommended to connect the external drain pipe; when connecting the external drain pipe, ensure that the motor is always filled with oil. The external drain pipe should be throttled at a certain degree, to maintain a back pressure of more than 3.5 Bar. When connecting the external drain pipe, in addition to maintaining a low back pressure, the wear contaminants generated inside the motor can be removed and a certain cooling effect can be achieved.
◎ There should be a running-in period before the motor is operated at full load. It is recommended to run for 1h at 30% of the Max. operating pressure.
