A6VE series
A6VE series
Bent-axis variable motor with an integrated planetary gearbox, mounted inside the track or wheel. Travel drive for rigs and excavators, with no external gearbox or cardan shaft.
Features
- Variable plug-in motor with swash-plate type axial tapered-piston rotor group, for hydrostatic drives in open and closed circuits
- Integrated into mechanical gearboxes thanks to the recessed mounting flange at the centre of the housing (a very space-saving design)
- Easy to install — simply plug into the mechanical gearbox (no configuration instructions to follow)
- Test unit ready for installation
- Especially for mobile machinery applications
- Displacement is infinitely variable between Vg max and Vg min = 0
- The wide control range lets the motor meet high speed and high torque requirements
- Output speed depends on pump flow and motor displacement
- Output torque increases with the differential pressure between high and low pressure sides and with displacement
