Features
– Variable motor with an 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 wide control range enables the variable motor to satisfy the requirement for high speed and high torque.
– The displacement is infinitely variable from Vg max to Vg min = 0.
– The output speed depends 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 side and with increasing displacement.
– Wide control range with hydrostatic transmission
– Wide selection of control devices
– Cost savings through elimination of gear shifts and possibility of using smaller pumps
– Compact, robust bearing system with long service life
– High power density
– Good starting characteristics
– Low moment of inertia
