Rexroth A6VM Series High-Performance Variable Displacement Piston Motors

Product Overview:

The Rexroth A6VM Series is a premier variable displacement motor featuring a bent-axis design, specifically optimized for hydrostatic transmissions in both open and closed circuits. With its extensive displacement control range, the A6VM motor facilitates seamless transitions between high-torque climbing and high-speed traveling conditions. This selection covers the full range: A6VM55, A6VM80, A6VM107, A6VM160, and A6VM200. We feature precision-configured models: A6VM107EZ4/63W-VAB027 and A6VM160HA1/63WVZB017H0A. This series serves as the power heart for crane winches, drilling rig power heads, concrete pumps, and excavator travel drives.

Key Technical Advantages:

• Wide Displacement Ratio: The displacement ratio of up to $V_{g \text{ max}} / V_{g \text{ min}} = 3.47$ allows machinery to significantly increase operating speeds without increasing pump flow.

• Extreme Pressure Durability: Rated for a nominal pressure of 400 Bar (5800 PSI) with peak capabilities reaching 450 Bar, ensuring long-term reliability under severe loads.

• Versatile Control Logic: * EZ (Electric Proportional): Achieves precise, infinitely variable speed regulation via electric signals.

  • HA (Automatic High-Pressure Control): Automatically adjusts displacement based on system load pressure for self-adaptive torque output.

• Optimized Power Density: The compact bent-axis design delivers massive mechanical power within restricted installation envelopes.

• Target Applications: Travel drives (rollers, crawlers), winch drives (cranes, windlasses), rotary drilling rigs, forestry machinery, and injection molding.
