Rexroth AA6VM80 Motor | AA6VM80HD2, AA6VM80EZ3 | Axial Piston Variable Motor

Rexroth AA6VM80 Series High-Pressure Axial Piston Variable Motors

Product Overview: The Rexroth AA6VM80 Series is a global performance leader in heavy-duty mobile machinery drive systems. Featuring a sophisticated bent-axis piston design, this variable displacement motor is engineered for both open and closed circuits, providing exceptional power density across an expansive speed range. This selection features two primary configurations: AA6VM80HD2/63W-VSC52O (Hydraulic Proportional Control) and AA6VM80EZ3/63W-VSC520B-ES (Electronic Proportional Control). Renowned for its superior starting torque and shock resistance, the AA6VM80 is the top choice for excavator travel drives, rotary drilling rigs, crane winches, pavers, and hydrostatic transmissions.

Key Technical Advantages:

• Versatile Precision Control: HD2 provides stable hydraulic proportional regulation, while EZ3 utilizes electronic proportional control for seamless integration with vehicle ECUs, allowing for automated speed management.

• Bent-Axis Efficiency: The classic 45° bent-axis architecture ensures maximum mechanical efficiency, delivering smooth and massive torque output even under low-speed, heavy-load conditions without “crawling.”

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, maintaining ultimate reliability under extreme stress cycles.

• Rugged Series 63 Architecture: Features reinforced bearing systems and VSC standard flanges for superior vibration resistance and extended service life in harsh construction environments.

• Ultra-Wide Speed Ratio: Supports stepless adjustment from maximum to minimum displacement, catering to both high-speed travel and low-speed precision work.

• Target Applications: Crawler travel propulsion, heavy-duty winch systems, construction rotary drives, and forestry machinery propulsion.
