Bosch Rexroth Variable Plug-in Motor A6VE

Features
––Variable plug-in motor with axial tapered piston rotary group
of bent-axis design, for hydrostatic drives in open and closed
circuits
––Far-reaching integration in mechanical gearbox due to a
recessed mounting flange located on the center of the case
(extremely space-saving construction)
––Easy to install, simply plug into the mechanical gearbox (no
configuration specifications to be observed)
––Tested unit ready to install
––For use especially in mobile applications
––The displacement can be infinitely changed from
Vg max to Vg min = 0.
––The wide control range enables the variable motor to satisfy
the requirement for high speed and high torque.
––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-pressure and low-pressure side and with
increasing displacement.

Hydraulic fluid
Before starting project planning, please refer to our data
sheets RE 90220 (mineral oil), RE 90221 (environmentally
acceptable hydraulic fluids), RE 90222 (HFD hydraulic fluids)
and RE 90223 (HFA, HFB, HFC hydraulic fluids) for detailed
information regarding the choice of hydraulic fluid and application
conditions.
The variable motor A6VE is not suitable for operation with
HFA hydraulic fluid. If HFB, HFC, or HFD or environmentally
acceptable hydraulic fluids are used, the limitations regarding
technical
data or other seals must be observed.

Details regarding the choice of hydraulic fluid
The correct choice of hydraulic fluid requires knowledge of the
operating temperature in relation to the ambient temperature: in
a closed circuit, the circuit temperature, in an open circuit, the
reservoir temperature.
The hydraulic fluid should be chosen so that the operating
viscosity in the operating temperature range is within the
optimum range (νopt see shaded area of the selection diagram).
We recommended that the higher viscosity class be selected
in each case.
Example: At an ambient temperature of X °C, an operating temperature
of 60 °C is set in the circuit. In the optimum viscosity
range (νopt., shaded area) this corresponds to the viscosity
classes VG 46 or VG 68; to be selected: VG 68.

Note
The case drain temperature, which is affected by pressure and
speed, can be higher than the circuit temperature or reservoir
temperature. At no point of the component may the temperature
be higher than 115 °C. The temperature difference specified
below is to be taken into account when determining the
viscosity in the bearing.
If the above conditions cannot be maintained due to extreme
operating parameters, we recommend flushing the case with a
flushing and boost pressure valve (see page 29).
