Rexroth AA6VM Series Bent Axis Axial Piston Variable Motors

Product Overview:

The Rexroth AA6VM series is a high-pressure, bent-axis axial piston variable displacement motor designed for both open and closed-circuit hydraulic systems. These motors are the premier choice for mobile machinery (e.g., excavator travel drives, tracked vehicles) and industrial applications (e.g., winches, rotary drilling rig swings). Featured models such as the AA6VM80HZ3/63W-VSC520B-E and AA6VM55EP1/63W000-VSD520A leverage a robust bent-axis design to deliver high torque output and high-speed switching across an extensive displacement range, significantly enhancing machine maneuverability and load adaptability.

Key Technical Advantages:

• Wide Displacement Ratio: Features a large modulation range ($V_{max} / V_{min}$), allowing equipment to transition seamlessly between heavy-load climbing (high displacement/torque) and rapid travel (low displacement/high speed).

• High-Pressure Durability: Rated for continuous operation at 400 Bar (5800 PSI) with peak capabilities up to 450 Bar, ensuring long-term stability under extreme tractive efforts.

• Versatile Control Options: Supports HZ (Hydraulic Two-point Control), EP (Electric Proportional Control), and HA (Automatic High-pressure Control) to meet diverse automation and power-matching requirements.

• Superior Power Density: The compact bent-axis architecture allows the motor to output massive power while maintaining a small footprint, ideal for installation in constrained wheel hubs or winch drums.

• 100% OEM Standard Compatibility: Manufactured to strict Rexroth Series 63 specifications, ensuring mounting flanges and splined shafts (e.g., VSC520, VSD520) align perfectly with original travel reducers.
