BMV Series Orbital Motors Cycloid Hydraulic Motor
Features
Advanced Structure: The BMV series cycloid hydraulic motors feature an advanced planar valve-plate structure. With a stud-inserted rotor-stator pair, they offer high working pressure, high efficiency, and long service life. Multifunctional variants can be designed per user needs.
Efficient Operation: Optimized rotor-stator design results in low starting pressure and high, sustained efficiency.
High Load-Bearing Capacity: High working pressure enables large torque output. Tapered roller bearings allow strong axial and radial load bearing, letting the motor directly drive work mechanisms, expanding applications.
Precision and Durability: The planar valve-plate ensures high precision and strong self-compensation after wear, maintaining high volumetric efficiency, long life, and stable speed under load.

- The rated speed and torque refer to the output values under rated flow and pressure.
- The continuous value refers to the maximum value at which the motor with this displacement can operate continuously.
- The intermittent value refers to the maximum value at which the motor with this displacement can operate for 6 seconds within 1 minute.
- The peak value refers to the maximum value at which the motor with this displacement can operate for 0.6 seconds within 1 minute.
