Fixed motor with axial tapered piston rotary group of bent axis design, for hydrostatic drives in open and closed circuits. For use in mobile and stationary application areas. The output speed is dependent on the flow of the pump and the displacement of the motor. The output torque increases with the pressure differential between the high and low pressure sides and with increasing displacement.

During commissioning and operation, the axial piston unit must always be filled with hydraulic oil and vented with air. The above precautions must also be observed after a relatively long period of inactivity, since the axial piston unit may drain hydraulic oil back into the tank via the hydraulic line.
Especially in the "transmission shaft up" installation position, oil filling and exhaust must be carried out thoroughly, otherwise there will be dangers such as oil-free operation.
