Rexroth A6VM Series High-Pressure Variable Bent Axis Motors

Product Overview:

The Rexroth A6VM Series is globally recognized as the technology benchmark for bent-axis variable axial piston motors. Designed for both open and closed-circuit hydrostatic transmissions, the A6VM series achieves a perfect balance between high startup torque and high-speed transit through its expansive displacement ratio ($V_{max}/V_{min}$). This category covers the full spectrum from the compact A6VM55 to the heavy-duty A6VM250. These motors are the definitive power units for crawler excavator travel drives, rotary drill rig power heads, large crane winches, and road machinery.

Key Technical Advantages:

• Superior Displacement Ratio: Features expansive variability, supporting stepless adjustment from maximum to minimum displacement to significantly improve machine efficiency and fuel economy.

• Precision Control Modules:

  • EP2 (Electric Proportional): Achieves precise electronic displacement adjustment via proportional solenoids, ideal for integration with modern electronic control systems.

  • HD2 (Hydraulic Proportional): Provides linear displacement adjustment based on pilot pressure signals for refined operator feedback.

• Extreme Pressure Resilience: Rated for a continuous operating pressure of 400 Bar with peak capabilities reaching 450 Bar (6500 PSI), built to withstand intense shock loads in harsh environments.

• Elite Power Density: The compact bent-axis design delivers massive torque within a minimal footprint and ensures excellent cold-start performance.

• Target Applications: Excavator travel drives, industrial winches, pavers, rollers, and mining machinery.
