Variable Speed Rexroth Type Piston Motor A6VM Bent Axis Design High Power Density

Variable Speed Rexroth Type Piston Motor with Maximum Speed of 3900 to 6150 rpm


Features:


1. Variable motor with axial tapered piston rotary group of bent axis design, for hydrostatic drives in open and closed circuits.

2. For use in mobile and stationary application areas.

3. The wide control range enables the variable motor to satisfy the requirement for high speed and high torque.

4. The displacement is infinitely variable from Vg max to Vg min = 0 .

5. The output speed is dependent on the flow of the pump and the displacement of the motor.

6. The output torque increases with the pressure differential between the high and low pressure sides and with increasing displacement.

7. Wide control range with hydrostatic transmission.

8. Wide selection of control devices.

9. Cost savings through elimination of gear shifts and possibilityof using smaller pumps

10. Compact, robust bearing system with long service life.

11. High power density.

12. Good starting characteristics.

13. Low moment of inertia.

Applications:


1. Construction machinery (excavators, loaders): High torque output and compact bent-axis design adapt to excavator operations, while hydrostatic transmission improves energy efficiency‌.
2. Construction cranes: Hydrostatic transmission precisely controls crane lifting speed, and spherical oil distribution ensures stability under high pressure‌.
3. Agricultural machinery (harvesters, tractors): Extreme temperature resistance (-40°C~115°C) suits field conditions, and high power density improves harvester efficiency‌.
4. Mining equipment: Long-life bearings resist dusty environments, and dual pressure ratings (400/450 bar) handle sudden load shocks‌.
5. Port machinery (gantry cranes, Reach Stacker): Low inertia moment enables rapid gantry crane operations, and multiple flange interfaces support port equipment integration‌.

Competitive Advantage:


1. High power density axial piston motor (>0.5 kW/kg)‌ supports heavy machinery with compact space requirements‌.

2. Infinitely adjustable displacement (0~Vg max)‌ dynamically adapts to load changes via swashplate tilt, improving energy efficiency by 12%-18%‌.

3. Bent-axis piston motor design‌ operates in open/closed circuits with 20%-30% lower oscillating torque‌.

4. Modular controls (HA/HD/HZ)‌ enable multi-stage speed adjustment and remote automation for industrial processes‌.

5. Extreme temperature-resistant piston components (-40°C~115°C)‌ prevent thermal failures in agricultural and polar equipment‌.
