Rexroth A6VM80 Series High-Pressure Variable Bent Axis Motors

Product Overview:

The Rexroth A6VM80 Series is a cutting-edge bent-axis variable axial piston motor, expertly engineered for both open and closed-circuit hydrostatic transmissions. With its superior displacement adjustment range, the A6VM80 allows machinery to operate across an expansive speed spectrum while providing precise torque control. This category features high-precision models: A6VM80HA1U (Automatic High-Pressure Related Control) and A6VM80EZ4 (Electric Proportional Control). These motors are the definitive power heart for crawler drives, crane winches, rotary drill rig power heads, and heavy-duty forestry equipment.

Key Technical Advantages:

• Elite Displacement Ratio: Features infinite variability from maximum to zero displacement, enabling a seamless transition between high-torque startup and rapid transit.

• Versatile Control Logic:

  • HA1U (High-Pressure Related Control): Automatically adjusts displacement based on load pressure, enabling automatic multi-speed functionality without external signals.

  • EZ4 (Electric Proportional Control): Features advanced solenoid technology for seamless integration with modern PLC electronic control systems for remote precision.

• Extreme Pressure Resilience: Rated for a continuous operating pressure of 400 Bar with peak capabilities reaching 450 Bar, ensuring an extended service life under intense shock load conditions.

• Reinforced Shaft Configurations: Various high-strength shaft options such as PZB016A and VZB020PB ensure stable power transmission to planetary gearboxes.

• Target Applications: Excavator travel drives, concrete pumping slewing mechanisms, large drill rig drives, and marine winches.
