Rexroth A6VM107 Series High-Pressure Electric Proportional Variable Motors

Product Overview: The Rexroth A6VM107 Series is the industry performance benchmark for heavy-duty mobile machinery drives. Featuring a sophisticated bent-axis variable displacement design, it provides constant power output across an exceptionally wide speed range. This featured selection includes two elite electronic proportional configurations: A6VM107EZ3/63W-VAB0270HB and A6VM107EZ4/63W-VAB027PB. With precise electrical regulation, the A6VM107 is the premier choice for excavator travel and swing drives, road cold planers, crane winch systems, rotary drilling rigs, and heavy-duty crawler vehicles.

Key Technical Advantages:

• Precise EZ3/EZ4 Proportional Control: Supports electronic proportional displacement regulation. The EZ4 provides enhanced sensitivity, allowing seamless integration with vehicle control systems for intelligent speed management and power distribution.

• Peak Pressure Resilience: Rated for continuous operation at 400 Bar (5800 PSI) with peak pressures reaching 450 Bar, ensuring stability and reliability under extreme loads.

• Bent-Axis High-Efficiency Design: The unique 45° bent-axis piston layout delivers maximum mechanical efficiency and starting torque, ensuring smooth, powerful operation even at ultra-low speeds.

• Rugged Series 63 Architecture: Features reinforced bearings and VAB standard interfaces for superior vibration resistance and extended service intervals.

• Ultra-Wide Speed Ratio: Supports stepless adjustment from maximum to minimum displacement, allowing for seamless transitions between high-speed travel and low-speed precision tasks.

• Target Applications: Crawler travel propulsion, heavy-duty crane winches, rotary drilling rig power heads, and hydrostatic transmissions.
