Core Technical Specifications:-
- Motor Architecture: Oblique Axis Variable Axial Piston Motor
- Displacement Sizes: 55, 80, 107, 160, 200 cc/rev
- Nominal Operating Pressure: 400 bar
- Maximum Peak Pressure: 450 bar
- Circuit Compatibility: Open and Closed-Loop Systems
Key Features & Engineering Advantages:-
- Infinite Displacement Control (Down to Zero): The motor can alter its internal displacement to any value between maximum volume (Vg max) and absolute zero (Vg min = 0). This allows for precise, infinite adjustment of the system's speed and torque to perfectly match real-time load requirements.
- Exceptional Power Density & Low Inertia: Generates massive power output from a compact, rugged package. It provides excellent starting characteristics and rapid, highly responsive speed changes with minimal mechanical resistance.
- Advanced Oblique Axis Design: Features an inclined shaft structure with one-piece tapered plungers and tightly sealed piston rings. This advanced hydrostatic architecture guarantees remarkably smooth, dependable fluid power transmission.
- Versatile Control Options: Readily compatible with a wide array of electric, hydraulic, and mechanical control devices. This grants engineers maximum flexibility to customize pressure, speed, and torque management without altering hardware.
- Unmatched Energy Efficiency: By dynamically adjusting displacement to match the exact load requirement, the motor drastically reduces overall energy consumption, lowering operational fuel costs and minimizing system heat.
- Heavy-Duty Bearing System: Equipped with a compact yet incredibly tough bearing system specifically designed to withstand extreme mechanical stress and high torque over a long, maintenance-friendly service life.
Working Principle:-
The A6VM operates on an advanced hydrostatic transmission principle. Hydraulic fluid supplied by the system pump drives the precisely machined pistons, which are arranged in an inclined (oblique) configuration. By utilizing the variable displacement system to alter the angle and movement of these pistons, the motor instantly adjusts its output speed and torque according to the exact pressure differential between the input and output lines.
Ideal Industry Applications:-
Because of its wide control range and ability to handle both high speeds and extreme torque, the A6VM Series is the ultimate hydraulic drive for:
- Mobile Construction Machinery: Excavators, bulldozers, and mobile cranes requiring flexible speed-torque ratios and rapid response times.
- Heavy Agricultural Equipment: High-capacity tractors, combine harvesters, and forestry machinery requiring efficient, adaptable power delivery.
- Industrial Manufacturing: Heavy-duty conveyors, industrial presses, and hydraulic winches that demand precise motion control and superior energy efficiency.
