A2FE Series 6x Replacement Axial Piston Fixed Motor is a high-performance axial piston motor designed to convert hydraulic pressure and flow into consistent rotary power for demanding hydrostatic drive systems. As a dependable axial piston hydraulic motor replacement, it supports stable operation in construction, material-handling, drilling, mining, marine and other heavy-duty mobile or industrial equipment.
1. Compact plug-in design: The recessed central mounting flange enables deep gearbox integration and helps minimize the overall drive-system envelope.
2. Bent-axis piston technology: Delivers efficient conversion of hydraulic energy into continuous rotary motion with high torque capability.
3. High-pressure performance: Selected sizes operate at nominal pressures up to 400 bar and maximum pressures up to 450 bar.
4. Wide displacement range: Available from 28.1 to 355 cm³/rev to meet different speed, torque and machine-size requirements.
5. Predictable fixed-displacement output: Motor speed is determined by inlet flow and displacement, while output torque increases with pressure differential.
FAQ
Q1. What is an axial piston fixed motor?
An axial piston fixed motor converts hydraulic pressure and flow into rotary torque. In the A2FE motor, pressurized oil acts on pistons arranged in a bent-axis rotary group, causing the drive shaft to rotate. Because the displacement remains constant, motor speed is mainly determined by inlet flow, while output torque depends largely on the pressure difference across the motor.
Q2. What is the difference between a fixed and variable displacement axial piston motor?
A fixed displacement axial piston motor has a constant displacement per revolution. It is generally selected when the required speed range can be controlled through pump flow or a mechanical gearbox. A variable displacement motor can change its displacement during operation, providing a wider torque and speed range, but it also requires additional controls and a more complex hydraulic system. The A2FE Series 6x is a fixed displacement motor designed for compact gearbox-integrated drives.
Q3. Can the A2FE Series 6x operate in both open and closed hydraulic circuits?
Yes. The A2FE Series 6x axial piston hydraulic motor is designed for hydrostatic drives in both open and closed circuits. However, the complete system must still provide the correct flow, pressure, cooling, filtration and case-drain conditions for the selected motor size.
Q4. How do I choose the correct A2FE motor displacement?
Start with the required output torque, operating speed, available pump flow and system pressure. A larger displacement normally produces more torque at the same pressure but runs more slowly at the same flow. A smaller displacement provides higher speed but less torque under the same conditions.
The A2FE Series 6x is available in displacements from 28.1 to 355 cm³/rev. Shaft type, mounting flange, port arrangement, direction of rotation and gearbox interface should also be confirmed before ordering.
