Rexroth A6VM Series High-Pressure Variable Axial Piston Motors

Product Overview:

The Rexroth A6VM Series is a bent-axis variable displacement axial piston motor engineered for high-performance hydrostatic transmissions in both open and closed circuits. With an exceptionally wide displacement adjustment range, the A6VM series provides optimal power delivery under diverse load conditions. This category features the full spectrum from A6VM55 to the massive A6VM500, highlighting precision configurations such as A6VM160HZ and A6VM160HA1T. These motors are the definitive power source for rotary drilling rig heads, excavator travel drives, crane winch systems, and large-scale agricultural transmissions.

Key Technical Advantages:

• Massive Displacement Ratio: Featuring a high variable range ($V_{max}/V_{min} = 3.47$), allowing machinery to switch smoothly from high-torque startup to high-speed travel without gear changes.

• Superior Volumetric Efficiency: The iconic 40° bent-axis technology minimizes internal leakage, ensuring efficient power conversion even at maximum operating pressures.

• Versatile Control Options:

  • HZ Control: Two-point hydraulic control for instantaneous switching between high and low-speed ranges via pressure signals.

  • HA Control: Automatic displacement adjustment based on system pressure, enabling intelligent load-sensing operation.

• Extreme Pressure Resilience: Rated for a continuous pressure of 400 Bar with peak capabilities reaching 450 Bar (6500 PSI), built for the most rugged environments.

• Target Applications: Crawler travel motors, heavy-duty winch drives, road milling machines, and forestry harvesters.
