Rexroth A6VM Series High-Pressure Axial Piston Variable 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 of up to $V_{max}/V_{min} = 3.47$). This selection covers the full spectrum of displacements, including compact models A6VM55, A6VM80, mid-range A6VM107, A6VM140, and heavy-duty A6VM160. Core configurations featured include A6VM80HA1R1/63W-VZB0170PA (Automatic High-Pressure Control). Whether in travel drives, winches, or industrial equipment, these motors deliver consistent torque at peak pressures up to 450 Bar.

Key Technical Advantages:

• Superior Speed Flexibility: Stepless displacement adjustment from maximum to minimum allows for high starting torque and high-speed operation, suitable for diverse industrial tasks.

• HA1 Automatic High-Pressure Control: Automatically adjusts displacement based on load pressure to optimize energy efficiency and prevent system overload while maintaining maximum power output.

• 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.

• Excellent Starting Characteristics: Utilizing classic bent-axis technology, it provides smooth and powerful startup torque even at low rotational speeds, ensuring creep-free operation.

• Target Applications: Crawler travel drives, rotary drilling power heads, concrete mixer drives, crane winches, and heavy-duty conveyor systems.
