A10FM Fixed Displacement Motor

A10FM Size 10…63(10,11,14,16,18,23,28,37,45,58,63)

Nominal pressure 280 bar

Peak pressure 350 bar

Open and closed circuit

Characteristic

Versatile Hydrostatic Transmission: The Rexroth A10FM motor is designed with a swash plate configuration for hydrostatic transmission and is suitable for both open and closed circuit scenarios.

Performance dynamics: Output speed is related to inlet flow, while output torque increases with the pressure gradient between the high- and low-pressure sides.

Wide range of applications: suitable for mobile and industrial applications, with long service life and high allowable output speed.

Compact and efficient design: The A10FM fixed displacement motor features the proven A10 rotary group, high power-to-weight ratio, installation space-saving plug-in version, low noise level and adheres to SAE standards for mechanical and hydraulic connections. Optional integrated anti-cavitation valve for specific applications such as fan drives.
