Axial piston motors
When applications require rapid changes in direction, high accelerations or constant power output at extreme pressures, HYDAC axial piston motors are the first choice. Their compact design and the rotating parts’ low moment of inertia enable them to respond to control commands with lightning speed. Whether used as a fixed displacement motor for uniform rotary motion or as a variable displacement motor to achieve a wide speed range – our motors convert hydraulic energy into mechanical force with maximum precision.

Swash plate technology for maximum performance
The technical superiority of our motors is based on optimised tribological systems (friction partners):
- High pressure resistance: designed for nominal pressures up to 450 bar and peak loads up to 500 bar.
- Fixed vs variable displacement motors: while fixed motors (MPF) provide a fixed displacement volume, variable motors (MPV) allow seamless control of torque and rotational speed – making them ideal for automatic transmissions in work machinery.
- Efficiency: optimised piston and sliding foot geometries minimise oil leakage losses, achieving an overall efficiency of over 90 %.

System solution for mobile use
With HYDAC, buyers and designers benefit from our extensive industry expertise in mobile hydraulics. Our axial piston motors often come with integrated valves (such as flushing or brake valves), which reduces the amount of tubing required and saves installation space. Thanks to their high shock and vibration resistance, they are ideal for use in construction machines, agriculture and off-highway applications. With HYDAC, you’re investing in a long-lasting drive component that minimises your operating costs thanks to the global availability of spare parts and expert support.
