Product details
1. Basic Product Definition
 
The BM1 Cycloidal Motor is a classic series of cycloidal hydraulic motors, a well-established Hydraulic orbit motor. It converts hydraulic energy into mechanical energy efficiently through an internal-gerotor meshing structure, serving as a core power actuator for low-speed heavy-load scenarios in small and medium-sized hydraulic system.
 
2. Core Structure & Working Principle
 
Core Structure
 
It adopts a shaft-distributed flow design with an inserted-pin cycloidal rotor-stator assembly, built-in automatic wear compensation devices and bidirectional relief valves. Its output shaft is fitted with heavy-duty bearings to withstand combined axial and radial loads, with no external drain line required. The compact and lightweight body suits installation in confined equipment spaces.
 
Operation Mechanism
 
High-pressure oil delivered by the hydraulic system enters the motor's working chambers, driving the rotor to perform eccentric orbital revolution inside the stator, and the motion is converted into low-speed high-torque rotation of the output shaft via the transmission assembly. Rolling pins reduce meshing friction to improve mechanical efficiency remarkably. Forward and reverse rotation can be easily achieved by adjusting the oil flow direction of the hydraulic system.
 
3. Key Performance Advantages (Consistent with General Features of Hydraulic orbit motor)
 
- Native low-speed high-torque performance: Operating speed ranges from 10 rpm to 750 rpm, generating powerful torque without additional reducers. It features low starting pressure, smooth startup and shutdown, and strong overload resistance for continuous heavy-duty operation.
- Excellent system compatibility: It can be connected in series or parallel within a hydraulic system, matching the pressure range of conventional hydraulic pump stations. Its optimized sealing structure tolerates high backpressure for flexible pipeline arrangement.
- Durability & easy maintenance: The rotor-stator pair compensates for wear automatically to maintain stable efficiency over long service cycles. Its highly interchangeable parts help cut maintenance and replacement costs significantly.
- Flexible installation: Multiple flange, output shaft and port options enable seamless integration into hydraulic system of construction machinery, agricultural equipment, sanitation vehicles and other devices.
 
4. Main Technical Specifications
 
- Displacement range: 50~500mL/r (models from BM1-50 to BM1-500)
- Continuous working pressure: 10~17MPa, peak shock pressure up to 21MPa
- Rated flow: ≤60L/min, compatible with oil supply parameters of small and medium-sized hydraulic systems
- Transmission types: keyed splines or straight keys for winch, slewing and travel drive loads
 
5. Application Industries
 
As a standardized Hydraulic orbit motor, it is widely applied in various hydraulic system:
 
1. Construction machinery: Slewing drives for mini excavators, attachment drives for loaders, rotation units for aerial work platforms
2. Agricultural machinery: Conveyor drum drives for harvesters, seeder actuators, irrigation hydraulic systems
3. Special vehicles: Brush drives for road sweepers, mold rotation units for injection molding machines, small hydraulic winches, light deck machinery for port facilities
4. Industrial equipment: Material conveyors, leather processing machines, compact hydraulic drive units for mining pipe tongs
