- FAQ
The A2FM12 is a fixed-displacement axial piston motor renowned for its robust performance and adaptability in demanding hydraulic systems. As part of the A2FM series, it combines high power density with reliability, making it a preferred choice for mobile and industrial applications where space and efficiency are critical .
This motor operates on a 40° bent-axis principle, where a tapered piston rotary group converts hydraulic energy into mechanical rotation. The design ensures smooth torque transmission and exceptional starting performance, even under heavy loads . The output speed correlates directly with the input flow rate from the pump, while the torque increases with the pressure differential between the high- and low-pressure sides . Key components, such as the one-piece pistons with integrated piston rings, optimize sealing and reduce internal leakage, enhancing both durability and efficiency .
The A2FM12 is widely used in construction machinery (e.g., excavators, compactors), industrial equipment (conveyors, mixers), agricultural machinery, and mining systems . Its compact dimensions and compatibility with international standards (e.g., ISO, DIN) allow seamless integration into existing hydraulic circuits .
