RE-A 91610/12.2015, Bosch Rexroth Corp.
Features
▶ Variable motor with axial tapered piston rotary group of
bent-axis design, for hydrostatic drives in open and
closed circuit
▶ For use in mobile and stationary applications
▶ The wide control range enables the variable motor to
satisfy the requirement for high speed and high torque.
▶ The displacement can be infinitely varied from V
gmax
to
V
gmin
=0.
▶ The output speed is dependent on the flow of the pump
and the displacement of the motor.
▶ The output torque increases with the pressure differen-
tial between the high and low-pressure side and with
increasing displacement.
▶ Wide control range with hydrostatic transmissions
▶ Wide selection of control devices
▶ Cost savings through elimination of gear shifts and
possibility of using smaller pumps
▶ Compact, robust motor with long service life
▶ High power density
▶ Good starting efficiency
▶ Version with 9-piston rotary group
▶ Good low speed characteristics
▶ High uniformity
▶ Sizes 60 to 215
▶ Nominal pressure 6500psi (450bar)
▶ Maximum pressure 7250psi (500bar)
▶ Open and closed circuits
