Rexroth AA6VM160 Variable Motor | AA6VM160HD2, AA6VM160HA1 | 450 Bar

Rexroth AA6VM160 Series High-Pressure Axial Piston Variable Motors

Product Overview:

The Rexroth AA6VM160 Series motor is a high-performance benchmark in modern hydrostatic transmission systems. Featuring an axial piston bent-axis design, the AA6VM160 is renowned for its superior power-to-weight ratio and wide control range (with a displacement ratio of up to $V_{max}/V_{min} = 3.47$). This selection covers core configurations: AA6VM160HD2/63W-VSD510B (Hydraulic direct control) and AA6VM160HA1/63L-VSD51X00A-S (Automatic high-pressure control). Whether in excavator travel drives, large winch systems, or industrial mixing equipment, these motors deliver consistent torque and precise speed regulation at peak pressures up to 450 Bar.

Key Technical Advantages:

• Superior Speed Flexibility: Stepless displacement adjustment from maximum to minimum allows for high starting torque and high-speed operation, suitable for complex industrial tasks.

• Versatile Control Synergy:

  • HD2 (Hydraulic Direct): Offers ultra-fast response times and precise positioning for highly automated systems.

  • HA1 (High Pressure): Automatically adjusts displacement based on load pressure to optimize energy efficiency and prevent system overload.

• High-Pressure Robustness: Rated for 400 Bar (5800 PSI) continuous and 450 Bar (6500 PSI) peak pressure. Built with reinforced rotating groups and heavy-duty bearings for extended service life in harsh environments.

• Excellent Starting Characteristics: Specialized valve plate designs ensure high mechanical efficiency, providing smooth startup and creep-free operation even at low rotational speeds.

• Target Applications: Crawler travel drives, winch machinery, rotary drilling power heads, large cranes, and heavy industrial conveyor systems.
