Rexroth A6VM Series High-Pressure Bent-Axis Variable Motors

Product Overview: The Rexroth A6VM Series stands as the definitive power powerhouse for hydrostatic transmission systems. Featuring advanced Bent-Axis technology, these motors provide an extensive displacement adjustment range, enabling a broad spectrum of speed and torque control without altering the input flow. This selection highlights heavy-duty configurations: A6VM80HA1R2/63W-VZB010HA (Material No. R902107538) and the high-capacity A6VM280EP6 with Series 71 valve integration. Renowned for their exceptional power density, the A6VM series is the definitive choice for crawler travel drives, rotary drilling rigs, pavers, and large-scale industrial mixing systems.

Key Technical Advantages:

• Versatile Control Modes: * HA1 Control: Automatic high-pressure adjustment that optimizes displacement based on load pressure for maximum system efficiency.

  • EP6 Control: Electric proportional adjustment, supporting remote digital displacement control via integrated proportional valves.

• Extended Variable Displacement: The bent-axis design allows seamless adjustment from maximum to zero (or minimum) displacement, providing superior acceleration and high-speed operation.

• High-Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) and peak pressures up to 450 Bar, engineered to withstand intense shock loads in harsh environments.

• Optimized Series 63/71 Design: Reinforced bearing systems ensure an extended service life and industry-leading starting torque efficiency in extreme conditions.

• Target Applications: Excavator travel and swing drives, heavy-duty crane winches, TBM propulsion systems, and marine deck machinery.
