Rexroth A6VM80HD1 Motor Axial Piston Motor Construction Machinery Travel Drive Motor

Product Overview:
The A6VM80HD1 is a high-performance bent-axis design axial piston motor from the renowned Rexroth A6VM series. Designed for both open and closed hydraulic circuits, this variable motor delivers exceptional power density, reliable starting characteristics, and smooth operation under extreme loads. With a displacement of 80 cc/rev and robust HD1 hydraulic control, it provides precise, stepless speed and torque adjustment for demanding mobile and industrial applications. This unit is a direct, high-quality replacement solution for original Rexroth equipment .

Technical Specifications:

• Model: A6VM80HD1/63W-VZB01000B (Material #: R902229026 / R902205922) 

• Type: Bent-axis design, variable axial piston motor 

• Displacement: 80 cm³/rev (continuously variable from Vg max to Vg min) 

• Nominal Pressure: 450 bar 

• Maximum Pressure: 500 bar 

• Control Type: HD1 - Hydraulic pilot control (displacement controlled by pilot pressure) 

• Design: Suitable for open and closed circuits 

• Speed Capability: Approved for very high-speed continuous operation 

Core Features:

• Bent-Axis Design: The robust angled shaft and conical piston design ensure high starting torque, excellent efficiency, and resilience against shock loads. The drive shaft can withstand radial loads .

• HD1 Hydraulic Control: Allows for precise, proportional displacement adjustment via external pilot pressure, enabling smooth speed and torque variations to match load demands .

• Wide Control Range: Displacement can be adjusted steplessly from maximum down to Vg min = 0, offering a broad operational speed range without needing a gearbox .

• High Power Density: Compact and lightweight construction delivers maximum power output in a minimal installation space, providing an excellent power-to-weight ratio .

• Optional Integrated Valves: Compatible with optional flushing and boost pressure valves, or integrated/attached counterbalance valves for enhanced functionality and load control .

• Durability: Engineered for long service life with robust bearings, good starting characteristics, and low inertia. Features a ball-contact distribution plate that automatically centers during rotation for high efficiency and low noise .
