A6vm hydraulic motor

The A6VM series is a high-performance axial piston variable displacement motor developed by Bosch Rexroth. Featuring a classic bent-axis design, it is widely used in open or closed-loop transmission systems for mobile machinery and industrial equipment. As Rexroth's flagship bent-axis variable displacement motor, the A6VM series hydraulic motor's technical parameter system primarily revolves around displacement adjustment, pressure ratings, and control logic.

First, Core Physical Parameters

1. Displacement Sizes: Extremely wide range, with standard sizes including 28, 55, 80, 107, 140, 160, 200, 250, 355, 500, and 1000. Displacement can be continuously adjusted from maximum to zero (Vgmin=0).

2. Pressure Rating:

Nominal Pressure (Rated): Typically 350 bar (35 MPa) or 400 bar (depending on series version).

Peak Pressure (Maximum): Up to 400 bar (40 MPa) to 450 bar.

Torque and Power: Output torque is proportional to pressure differential and displacement. For example, the A6VM160 specification achieves up to 1355 Nm torque and approximately 45 kW power under specific operating conditions.

Second, Control and Functional Parameters

1. Control Device:

HD: Hydraulic proportional control.

EP: Electro-proportional control (with proportional solenoid).

HA: High-pressure-related automatic control (automatically adjusts displacement based on load).

DA: Speed-related automatic control (suitable for travel drive applications).

Speed Range: Featuring an extremely high maximum speed limit due to its swashplate design, accommodating high-speed travel requirements.

Third, Core Technical Specifications of A6VM hydraulic motor

1. Structural Design: Utilizes a swashplate-type axial conical piston rotor assembly, enabling continuous displacement adjustment from maximum to zero.

2. Pressure Rating: Standard operating pressure is typically 35MPa, with peak pressure reaching 40MPa.

3. Displacement Range: Covers multiple displacement specifications including 28, 55, 80, 107, 140, 160, 200, 250, 355, 500, and 1000.

4. Control Methods: Supports multiple control logics, including hydraulic proportional control (HD), electrical proportional control (EP), two-point control (HZ/EZ), and automatic control related to high pressure or speed (HA/DA).

Fourth, Key Advantages

1. High Power Density: Compact structure and lightweight design achieve extremely high starting torque and power output through the swashplate design.

2. Wide Adjustment Range: Extensive stepless variable capacity adapts to dynamic conditions from low-speed high-torque to high-speed light-load operations.

3. Environmental Adaptability: Excellent suction characteristics and low-noise operation ensure stable performance in harsh industrial environments like high temperatures and humidity.

4. Easy Installation: Cartridge design facilitates integration into mechanical gearboxes, significantly saving installation space.
