Rexroth AA6VM Series High-Pressure Bent-Axis Variable Motors

Product Overview:

The Rexroth A6VM and AA6VM Series (AA6VM for ANSI standards) are the high-performance variable powerhouses of hydrostatic transmissions. Featuring advanced Bent-Axis technology, these motors provide an extensive displacement adjustment range ($V_{g\ max} / V_{g\ min}$), enabling a broad spectrum of speed and torque control without altering input flow. This featured selection includes heavy-duty configurations: AA6VM107HD1/63W-VSD52000B and AA6VM160HD2/63W-VSD520B. Renowned for their exceptional power density, the AA6VM series is the definitive choice for crawler travel drives, rotary drilling rigs, pavers, and primary transmissions in construction machinery.

Key Technical Advantages:

• Extended Variable Displacement: The bent-axis design allows seamless adjustment from maximum to zero (or minimum) displacement, providing superior acceleration and high-speed travel capabilities.

• Advanced HD Hydraulic Control: HD1 and HD2 control types offer precision displacement adjustment proportional to pilot pressure, ensuring smooth load handling and rapid response.

• High-Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) and peak pressures up to 450 Bar (6500 PSI), engineered to withstand intense shock loads in harsh environments.

• Optimized Series 63 Design: The Series 63 units feature reinforced bearing systems for extended service life and industry-leading starting torque efficiency.

• Target Applications: Excavator travel and swing drives, road machinery (rollers/pavers), crane winch motors, and heavy-duty industrial drives.
