Rexroth A6VM Series High-Pressure Variable Axial Piston Motors

Product Overview:

The Rexroth A6VM Series motor is a recognized benchmark for high performance in modern hydrostatic transmission systems. Featuring an axial piston bent-axis design, the A6VM is renowned for its superior power-to-weight ratio and wide control range (with a displacement ratio up to $V_{max}/V_{min} = 3.47$). This selection features heavy-duty core specifications: A6VM140 EP2, A6VM107 EP2, and the self-regulating A6VM160 HA1. Engineered for crawler travel drives, winch systems, and industrial transmissions, these motors deliver precise and smooth power output at peak pressures up to 450 Bar.

Key Technical Advantages:

• EP2 Intelligent Electric Proportional Control: Utilizes proportional solenoids for stepless displacement regulation, allowing for seamless integration with electronic vehicle controllers for high-precision operation.

• HA1 Automatic High-Pressure Control: Automatically adjusts displacement based on load pressure. It increases displacement for higher torque under heavy loads and reduces it for high-speed efficiency.

• Superior Speed Versatility: Smooth displacement adjustment down to minimum values provides a wide operating window, from high starting torque to high-speed cruise capabilities.

• High-Pressure Robustness: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Built with reinforced rotating groups for extended service life in harsh environments.

• Target Applications: Rotary drilling rig power heads, concrete mixer drives, excavator travel motors, large-scale crane winches, and heavy industrial drives.
