Main piston motor types
- Axial swashplate motors for compact fixed or variable-displacement drives
- Bent-axis motors for high-speed and high-efficiency applications
- Radial piston motors for high-torque, low-speed direct drives
- Open-circuit and closed-loop motors with different control and flushing needs
- Motor assemblies with brakes, reduction units, sensors or wheel interfaces
Performance selection
- Continuous, intermittent and starting torque requirements
- Minimum, rated and maximum operating speed
- Working and peak pressure plus acceptable case pressure
- Fixed or variable displacement and control response
- Efficiency, cooling, flushing, fluid and expected duty cycle
Replacement interface checks
- Complete code, displacement and design revision
- Shaft, mounting pilot, bolt pattern and permitted external loads
- Main ports, case drain, flushing and brake connections
- Rotation, brake release, sensors and control configuration
- Machine model, gearbox or wheel interface and operating symptoms
