A6VE107EP2/63W-VZU017FTA-SK A6VE Series Hydraulic Plug-in Motor

As a trusted China factory and reliable global supplier of industrial hydraulic drive components, Hengmeisi independently manufactures and optimizes the A6VE107EP2/63W-VZU017FTA-SK A6VE Series Hydraulic Plug-in Motor to solve the limitations of narrow control range, difficult installation, and poor high-pressure stability of traditional hydraulic traveling motors. The A6VE107EP2/63W-VZU017FTA-SK is a core 107cc large-displacement model in the upgraded A6VE 63 series, adopting advanced bent-axis tapered piston rotor technology and embedded plug-in structural design, which completely changes the bulky external installation mode of traditional hydraulic motors. This innovative plug-in structure allows the motor to be directly embedded into the gearbox interior, saving more installation space, reducing overall mechanical volume, and improving the integration degree of the whole machine equipment.

Our quality A6VE107EP2/63W-VZU017FTA-SK A6VE Series Hydraulic Plug-in Motor is designed for ultra-high pressure heavy-duty working conditions, with a nominal working pressure of 400bar and a peak instantaneous pressure up to 450bar, far exceeding the pressure resistance of ordinary A6V series hydraulic components. It is compatible with both open and closed hydraulic circulation systems, with strong system adaptability and flexible matching performance. The core operating advantage of this motor lies in its full-range variable displacement function, which can realize stepless adjustment from maximum displacement to zero displacement. It can automatically match high-torque low-speed climbing and high-speed flat traveling working conditions, effectively solving the problem of insufficient power or energy waste caused by fixed displacement output of ordinary motors.

In terms of operational stability, the A6VE107EP2/63W-VZU017FTA-SK adopts an integrated flushing and pressure boost valve structure, which can actively cool down and replace dirty hydraulic oil inside the system during continuous operation, avoiding high-temperature oil deterioration and component wear caused by long-term high-load operation. The whole machine abandons complex external pipeline layout, reduces pipeline pressure loss and leakage points, and improves the overall efficiency and stability of the hydraulic system. The optimized internal flow channel and rotor motion structure reduce operating vibration and noise, making the equipment run more smoothly and stably under long-cycle working conditions, greatly lowering the failure rate of mobile engineering machinery.

Core Product Advantages

1. Unique Plug-in Embedded Installation Structure

Different from the external flange installation of conventional hydraulic motors, the A6VE107EP2/63W-VZU017FTA-SK A6VE Series motor adopts a recessed center flange plug-in design, which can be directly inserted and positioned inside the mechanical gearbox without complicated positioning calibration and support frame fixing. This integrated installation method effectively saves 30%+ installation space, simplifies the overall mechanical structure, and reduces the assembly difficulty and later maintenance cost. The precision positioning tolerance design enables one-time accurate assembly, no need for repeated debugging, greatly improving equipment production and maintenance efficiency, which is very suitable for compact integrated engineering machinery design.

2. Full-range Zero Displacement Variable Control

Equipped with advanced EP2 electric proportional variable control system, the A6VE107EP2/63W-VZU017FTA-SK realizes precise electronic stepless adjustment of displacement. It supports automatic switching between zero displacement, medium displacement and full displacement, perfectly adapting to diverse working requirements such as equipment starting, climbing, flat running and no-load idling. When the equipment is in no-load state, the motor can adjust to zero displacement to eliminate idle power loss and reduce fuel consumption; when encountering heavy load climbing, it instantly switches to full displacement output high torque, realizing perfect balance between equipment power performance and energy-saving efficiency. The control response is sensitive and accurate, with stable signal transmission and no stuck delay.

3. Ultra-high Pressure Resistance and Extreme Working Stability

Built for super heavy-duty engineering scenarios, the A6VE107EP2/63W-VZU017FTA-SK has a rated pressure of 400bar and a peak pressure of 450bar, which can stably cope with impact load and high-pressure impact working conditions such as mountain operation, muddy road traveling and heavy-load excavation. The internal piston rotor group is forged with high-purity alloy steel and processed by multi-channel precision heat treatment, with super wear resistance and impact resistance. Equipped with Z2 reinforced high-pressure sealing assembly and FTA anti-fouling protection structure, it can effectively resist hydraulic oil impurity erosion, high-temperature aging and low-temperature brittleness, ensuring stable operation in -40℃~+120℃ extreme temperature environment and harsh dusty construction sites.

4. Integrated Valve Group Optimization and High System Adaptability

This A6VE Series hydraulic motor integrates flushing valve, boost valve and balance valve modules, realizing internal circulation cooling and pressure stabilization functions without external auxiliary valve groups. The built-in flushing system continuously replaces hot oil inside the motor during operation, avoiding thermal decay of hydraulic components and ensuring long-term continuous operation stability. The 63W series standardized configuration supports seamless matching with mainstream closed-circuit hydraulic systems of 20-50 ton excavators, rotary drilling rigs and mining machinery. It is fully interchangeable with original imported models in size, installation interface and performance, supporting direct replacement and upgrade without modifying the original equipment hydraulic system.

Model Code Detailed Explanation

Every character of A6VE107EP2/63W-VZU017FTA-SK corresponds to independent structural configuration, control mode and performance parameters, realizing standardized model identification and accurate model selection:

Product Structure and Manufacturing Technology

1. Bent-axis Tapered Piston Core Structure

Different from ordinary straight piston motors, the A6VE107EP2/63W-VZU017FTA-SK adopts bent-axis tapered piston rotary group design. The inclined piston layout optimizes the force transmission path, reduces internal friction and mechanical loss, and improves mechanical transmission efficiency to over 95%. The precision-machined cylinder body and piston matching gap is controlled within micron level, which effectively suppresses internal oil leakage and ensures stable torque output under variable load conditions. The overall structural rigidity is enhanced, avoiding deformation and vibration failure under long-term high-pressure impact.

2. High-grade Wear-resistant and Pressure-resistant Materials

All core load-bearing and moving parts of the A6VE Series motor adopt high-strength carburized alloy materials, which undergo vacuum quenching and precision grinding treatment to achieve ultra-high surface hardness and structural toughness. The sealing system adopts imported composite high-pressure resistant materials, which can resist high-pressure impact and medium corrosion for a long time; the bearing system adopts multi-row reinforced roller bearings, which can bear composite radial and axial loads, with a design service life of more than 20000 hours under rated working conditions. The surface of the motor shell is treated with anti-rust and anti-corrosion coating, adapting to outdoor rainy, dusty and humid working environments.

3. Intelligent Integrated Hydraulic Control System

The built-in EP2 electric proportional control module of the A6VE107EP2/63W-VZU017FTA-SK can receive electronic control signals in real time, realize active adjustment of motor displacement, and match the machine’s intelligent operating system. The integrated flushing and pressure stabilizing valve group automatically balances the system pressure and oil temperature, avoids local high pressure and high temperature of the hydraulic system, and effectively prevents component cavitation and wear failure. The modular integrated design reduces external accessory configuration, simplifies system maintenance, and improves the overall reliability of the equipment.
