Rexroth A6VM Series Variable Displacement Axial Piston Motors

Product Overview:

The Rexroth A6VM Series motor is a high-performance benchmark for hydrostatic transmissions. Featuring an axial piston bent-axis design, the A6VM is renowned for its superior power-to-weight ratio and wide control range (with a displacement ratio up to $V_{max}/V_{min} = 3.47$). This selection covers the full spectrum of displacements: A6VM55, A6VM80, A6VM107, A6VM160, and A6VM250. Featured configurations include A6VM80EZ3/63W-VZB0100PB (Electric Proportional Control) and A6VM55HD1D/63W-VZB0 (Hydraulic Pilot Control). Engineered for heavy-duty mobile and industrial drives, these motors deliver precise power at peak pressures up to 450 Bar.

Key Technical Advantages:

• EZ3 Intelligent Electronic Control: Utilizes electronic proportional regulation for seamless integration with vehicle controllers, enabling ultra-precise stepless displacement and load matching.

• HD1D Hydraulic Pilot Control: Offers rapid response times by adjusting motor speed via pilot pressure, ideal for heavy-duty environments with fluctuating loads.

• Superior Speed Versatility: Smooth displacement adjustment down to minimum values provides a wide operating window, from high starting torque to high-speed cruise capabilities.

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

• Target Applications: Crawler travel drives, heavy-duty crane winches, rotary drilling power heads, concrete mixer drives, and industrial conveyor systems.
