Aigat: Expert in precision winding of new energy vehicle drive motors and on-board electronics

In response to the trend of "flat wire" of new energy vehicle (NEV) drive motors, AJT relies on its self-developed corner bending device and shaping process patents to provide a full-link solution for flat wire winding with high groove full rate and zero damage to the paint film. It helps the main drive motor, OBC and DC/DC converter to achieve a leap in automotive-grade quality.

1. Industry background: The "flat wire" revolution of drive motors Under the trend of new energy vehicles pursuing long battery life and high power density, the "flat wire" transformation of drive motors is a foregone conclusion. Hairpin technology is key to improving motor efficiency due to its extremely high slot filling rate and excellent heat conductivity. However, the flat wire is brittle, the bending rebound is difficult to control, and the forming accuracy is extremely high, and any slight damage to the paint film may lead to the insulation failure of the whole machine. Based on its self-developed core technology, AJT provides global customers with automotive-grade precision winding guarantee.

2. Core technology: patent-driven intelligent manufacturing advantages Agatech is deeply involved in the field of non-standard automation, and has built a solid technical moat through full-stack self-research of software and hardware:

Precision mechanical empowerment: To address the pain points of flat wires that are prone to strain, we have applied "a corner bending device for flat wires" (Patent No.: ZL 2023 2 2778141.3) and "a coil shaping device (Patent No.: ZL 2023 2 2778193.0). Through precision guidance and flexible compensation mechanism, it ensures that the wire is subjected to uniform force in high-speed bending, the R-position of the bending angle is accurate, and the molding size error is controlled at the micron level.

Intelligent control brain: Equipped with the company's self-developed "automatic flat coil control system" (such as the V1.0 version vertical winding control system), realizing real-time closed-loop monitoring of speed and tension. The system has a built-in intelligent compensation algorithm, which can dynamically offset the tolerance fluctuation of the wire, completely solve the problem of stacking wires and deformation, and ensure the consistency of the inductor.

Strict quality verification: With a "coil parameter inspection tool" (patent number: ZL 2023 2 3281231.8), online monitoring of key dimensions can be realized at the production line, helping customers achieve the traceability requirements of automotive-grade quality.

3. Typical applications and value output This solution is widely used in: drive motor stator winding, on-board charger (OBC), DC/DC converter and wireless charging module. By adopting the Agate solution, customers can not only obtain equipment with excellent performance, but also rely on our latest authorized patented technologies in 2024 to significantly improve product pass-through rates, shorten the R&D cycle, and accelerate the global layout in the new energy track.
