A6VM Variable Motor – Reliable, Long-Lived and Extraordinarily Efficient
Power from Any Position:
The New A6VM Series 71 Variable Motor
The new series A6VM variable motor offers higher rated pressure and maximized power density. The
higher power density comes from a strong combination of increased rated pressure, higher speed, and
greater specific absorption volume. This new 9-piston motor is especially efficient at small swivel angles.
The drive is designed for smooth running over the entire swivel angle range, giving you power in any
position. That’s a big advantage at low rotational speeds – and you also get a lively motor startup response.
The motor’s zero swivel capability offers advanced traction drive functions like traction control (TCS),
plus high-performance braking – both also from Rexroth.

High-Performance Travel Drive
Rexroth Travel Drives:
Higher Pressure, More Efficiency
The new, high-performance travel drive from Rexroth provides increased power with reduced overall costs. The
travel drive consists of the new A6VM Series 71 hydraulic motor and the new A4VG Series 40 variable pump, for a
special emphasis on energy efficiency and concern for the environment. That means high performance, lower
mobile equipment fuel consumption and reduced harmful emissions. With its extended performance range, the
drive helps manufacturers of construction equipment, agricultural and forestry machinery, material handling
equipment and road vehicles meet the most challenging emissions standards.
