Product information
The OMP/BMP is the entry point to the cycloidal motor family.
It's the BM1 series - the one you start with when you need a direct drive motor and don't want to overcomplicate things. Low-speed, high-torque, cycloidal design. Simple, reliable, straightforward.
Inside, a planetary gear set does the work. Hydraulic pressure drives the rotor in a planetary motion inside the stator. The result is smooth rotation, even at very low speeds, with good starting torque.
The OMP BMP cycloid hydraulic motor is for applications that need direct drive without the cost of higher-performance options. Construction machinery, agricultural equipment, marine deck machinery - this is where it shows up.
How a cycloidal motor works - short version
Two gears inside. One fixed (stator), one rotating inside it (rotor). The rotor has one fewer tooth.
Hydraulic oil pushes the rotor, makes it roll around inside the stator. That rolling motion turns the shaft. Smooth rotation, no stalling at low speeds.
The design gives you three things:
Good starting torque - enough to move loads from a dead stop
Smooth low-speed operation - no jerking, no stalling
Compact size - fits in tight spaces
Product description
Application
Construction machinery - rotary drilling rigs, crane slewing mechanisms
Agricultural machinery - rotary implements, drive systems
Marine deck machinery - winches, anchor windlasses
Rotary and travel drive systems - various industrial applications
Six ways to learn about this motor
1. What flow and pressure can it handle?
BM1 is an entry-level motor. Medium pressure, moderate flow. Good for standard direct drive applications.
2. What's the starting torque like?
Good. The cycloidal design gives you good starting torque - enough to get moving under load.
3. How smooth is it at low speed?
Smooth. No stalling, no jerking. Good low-speed stability.
4. How compact is it?
Compact structure, high power density. Fits in tight spaces.
5. What about shock loads?
It handles them. Robust design, strong shock resistance.
6. What about maintenance?
Minimal. Keep the oil clean, change filters regularly. The motor is designed for reliable operation with minimal service.
Installation notes
Mounting: Wide range of displacements, mounting flanges, and output shaft configurations available. Confirm configuration matches your equipment.
Ports: Standard hydraulic ports. Check thread type and size.
Start-up: Run at reduced pressure first. Check connections before full load.
Maintenance: Keep oil clean, monitor temperature. Simple service.
Oil: Use recommended hydraulic oil. Regular oil and filter changes are essential.

FAQ
Q: What are the key features of the OMP/BMP series?
A: High torque, low-speed stability, compact structure, high power density, high starting torque, strong shock resistance, and low noise.
Q: What installation and configuration options are available for OMP/BMP motors?
A: A wide range of displacements, mounting flanges, and output shaft configurations are available to meet the integration requirements of various types of machinery.
Q: What causes insufficient torque or a drop in rotational speed?
A: Check whether the system pressure and flow rate are normal. If they are, the issue may be increased internal leakage caused by internal wear within the motor. Check the cleanliness of the hydraulic fluid; if it is contaminated, flush the system and replace both the fluid and the filter element.
Q: What causes excessive noise or abnormal vibration?
A: Possible causes: air entrainment in the fluid, poor coupling alignment, bearing wear, or loose mounting bolts. Troubleshoot in this order: bleed air → check the coupling → inspect bearing condition → tighten bolts.
Q: What causes shaft seal oil leakage?
A: The most common causes are excessive back pressure in the drain line, a blocked drain line, and shaft seal aging. The drain port must be connected directly back to the oil tank to ensure back pressure remains within the permissible range.
