Rexroth A6VM200HA2/63W-VAB02000A Hydraulic Motor
Overview
The Rexroth A6VM200HA2/63W-VAB02000A is a high-performance axial piston variable displacement motor manufactured by Bosch Rexroth. As part of the A6VM series, this motor features a bent-axis design and is engineered for hydrostatic transmissions in both open and closed circuits, delivering precise control of fluid flow and exceptional reliability in demanding mobile and industrial applications. The A6VM series is widely recognized for its high power density, wide control range, high overall efficiency, and long service life.
Technical Features
Bent-Axis Design with Axial Tapered Piston Rotary Group — The motor utilizes a bent-axis design with an axial tapered piston rotary group, specifically engineered for hydrostatic drives in both open and closed circuits. This design enables efficient hydraulic power conversion with high power density and smooth operation. The motor is available with a robust cast iron construction, ensuring durability under extreme conditions.
High Displacement & Pressure Capacity — The motor has a geometric displacement of 200 cm³ per revolution. It operates at a nominal pressure of 400 bar and can withstand maximum intermittent pressures up to 450 bar, making it suitable for high-pressure heavy-duty hydraulic systems. The A6VM series for sizes 28 to 200 offers 400 bar nominal pressure and 450 bar peak pressure, while larger sizes (250 to 1000) offer 350 bar nominal and 400 bar peak.
HA2 Automatic High-Pressure Related Control — The motor is equipped with HA2 control, which is an automatic high-pressure related control. This control system automatically adjusts the displacement depending on the operating pressure. The HA2 control has a pressure rise characteristic of Δp = 100 bar, meaning an increase in operating pressure of approximately 100 bar causes an increase in displacement from 0 cm³ to Vg max. The start of control is adjustable within a setting range of 80 to 350 bar. The control oil is internally taken from the high-pressure side of the motor, requiring no external control line. For reliable operation, an operating pressure of at least 30 bar is required. The HA2 positive control begins at Vg min (minimum torque, maximum speed) and ends at Vg max (maximum torque, minimum speed) with increasing operating pressure.
Stepless Variable Displacement — The displacement can be infinitely changed from Vg max (maximum displacement) to Vg min (=0), providing exceptional flexibility to adjust output speed and torque according to different working requirements. The output speed depends on the pump flow rate and the motor displacement, while the output torque increases with the pressure differential between the high-pressure and low-pressure sides and with increasing displacement.
Wide Speed Range — The motor is approved for very high rotational speeds while maintaining excellent low-speed operating characteristics. The A6VM200 offers a control range that can be swiveled to zero, satisfying both high-speed and high-torque requirements.
High Flow Capacity — The motor has a maximum flow rate of approximately 580 L/min, providing substantial hydraulic power for demanding applications.
High Torque Output — The motor delivers high torque output, ensuring powerful performance in heavy-load conditions. Output torque increases with the pressure difference between the high-pressure and low-pressure sides and with increasing displacement.
High Power Density — The motor offers high power density, meaning it delivers substantial power output relative to its size and weight, contributing to space-saving installation and efficient system design. This is achieved through a compact, robust long-life bearing system.
FKM Seals for Wide Temperature Compatibility — Equipped with FKM (fluoroelastomer) seals, this motor is compatible with various hydraulic fluids and suitable for operation across a wide temperature spectrum, ensuring reliable performance in diverse operating conditions.
SAE Standardized Mounting and Interface — The motor features an SAE J744 152-4 mounting flange (SAE "D", 4-bolt connection), a splined shaft DIN 5480 (W80x3x25x9g for size 200), and SAE J518 Code 62 working ports (high-pressure series flange connections) with metric threads for mounting screws. The direction of rotation is reversible.
Good Starting Characteristics & Low Inertia — The motor features excellent starting characteristics and low moment of inertia, enabling smooth and responsive operation even under heavy starting loads.
Series 63 Index — The 63W series index indicates Series 6, Index 3, Standard version, representing the latest design iteration within the A6VM product family.
Standard Configuration — This specific configuration (VAB02000A) does not include special fitted options such as a flushing and boost-pressure valve or a speed sensor, representing a standard configuration for HA control.
Key Functionalities
Hydrostatic Transmission in Open and Closed Circuits — The motor is designed for hydrostatic drives in both open and closed circuits, providing versatility for various hydraulic system configurations. In closed circuit systems, the motor operates within a sealed hydraulic loop where fluid is continuously recirculated between the pump and motor, minimizing losses and leakage. In open circuit systems, fluid is supplied from a central pump through a directional control valve and returns to the reservoir after each cycle.
Stepless Speed and Torque Control — The motor's output speed depends on the pump flow rate and the motor displacement, while the output torque increases with the pressure differential between the high-pressure and low-pressure sides and with increasing displacement. The wide control range enables the variable motor to satisfy requirements for both high speed and high torque, with displacement infinitely adjustable from maximum to zero.
HA2 Automatic Pressure-Related Displacement Control — The HA2 control system automatically adjusts the motor's displacement based on the operating pressure. When the operating pressure reaches the start of control setpoint (adjustable from 80 to 350 bar), the controller swivels the motor from Vg min to Vg max with increasing pressure. The pressure rise characteristic of Δp = 100 bar means the full displacement is achieved after an approximately 100 bar increase. The control oil is internally taken from the high-pressure side, requiring no external control line.
High Starting Torque — The bent-axis design naturally provides excellent starting characteristics and high starting torque, enabling the motor to easily overcome heavy breakaway loads in demanding applications such as excavators, cranes, and other heavy machinery.
Energy Efficient Operation — The variable displacement capability enables energy savings by allowing the motor to deliver only the flow and torque required by the load. By eliminating the need for gear shifts and enabling the use of smaller pumps, the A6VM series contributes to reduced energy consumption and lower operating costs. The compact bearing system also contributes to long service life and high efficiency.
Compact System Integration — The compact design and robust construction allow for easy integration into both mobile and stationary hydraulic systems, with standardized SAE mounting interfaces ensuring compatibility with existing equipment.
High Reliability & Low Maintenance — With its robust construction, high-quality materials, wear-resistant components, and high-precision bearings, the motor ensures long-term operational stability with minimal maintenance requirements, reducing downtime and total cost of ownership.
Cost Savings Through Simplified Design — The wide control range enables cost savings through the elimination of gear shift mechanisms and the possibility of using smaller pumps, reducing overall system complexity and component costs.
