Rotary piston motor

The AM motor series from Rollstar is an axial piston motor with a constant stroke volume.

The torque is generated directly on the drive shaft. There are no losses due to eccentrics, swash plates, cam plates and the like. As a result, the motor has a high mechanical efficiency.

Torque range: 0 to 2300 Nm

The rotary piston motor M from Rollstar is a very robust hydraulic motor, which shows a slight starting behavior over the entire speed range.

The continuous shaft is ideal for attaching planetary gears or a second shaft end for braking or rotational speed measurement. The oil connections are available in axial or radial design. 

The motor is suitable for a maximum continuous nominal pressure of 145 bar and intermittently up to 210 bar with speeds of 0–1000 rpm..

Our rotary piston motors are available in four sizes of 65 cm3 up to 750 cm3. These four sizes cover a torque range of 0–2300 Nm.
