On July 4, 2024, Midea Industrial Technology’s Welling auto parts appeared at the 16th Annual Meeting of Automotive Power System Technology (TMC2024) hosted by the Chinese Society of Automotive Engineering, and the field of electric drive products including drive motor flat wire stator, drive motor permanent magnet rotor, drive motor round wire stator were displayed on site. Since its establishment in 2018, Weiling Auto Parts has grown into an innovation-driven automotive core parts supplier in the new era. Weiling Auto Parts will actively participate in industry activities, deeply exchange the development trend of new energy vehicle technology, and contribute to promoting the rapid development and evolution of the industry.

8327-1600 In 2024, the market share of new energy vehicles continues to increase, and the electric drive system is entering a comprehensive and deep-level iterative innovation stage of high voltage, high-speed, highly integrated, intelligent energy management and thermal management combined with the vehicle, integration with the chassis and other systems and intelligent control, as well as basic materials, chips, processes and digital development. Weiling auto parts will rely on the advantages of technology research and development, lean manufacturing and high-quality delivery to optimize and improve the driving experience of new energy vehicles, such as driving range, intelligent driving and driving comfort, and inject energy into the development of global green travel.

Taking the flat wire stator of the high voltage (800V) HairPIN drive motor of Welling auto parts displayed this time as an example, the product is suitable for pure electric vehicle drive system and hybrid electric vehicle drive system, the power range covers 100kw-240kW, and the peak speed is greater than 22000rpm. And can customize stator with different power/torque according to customer needs (hybrid, pure electric). In addition, the product has high slot full rate, high torque density, high efficiency characteristics, and has been fully verified to ensure manufacturing stability and product reliability.

Weling auto parts Low voltage (400V) X-pin & Hair-pin drive motor flat wire stator supports high torque density X-pin and Hair-pin optional, and adopts the same production line compatible design, matching 400V hybrid/extended range/pure level station. The product can be customized according to customer needs (hybrid, pure electric) stator of different power/torque, with high slot full rate, high torque density, high efficiency product characteristics, and through full process verification, to ensure manufacturing stability and product reliability.

In addition, Welling Auto Parts also displayed the pre-formed drive motor flat wire stator, drive motor permanent magnet rotor, drive motor round wire stator. Among them, the drive motor flat line stator flat line layer number can be adjusted, and up to 11 layers, suitable for a new generation of high voltage drive motor solutions, high compatibility products and high flexible production line, to meet the low manufacturing cost needs of the OEM. Drive motor permanent magnet rotor power range covers 50kw-240kW(oil cooled, water cooled optional), can be customized according to customer needs (hybrid, pure electric) rotor with different power/torque; Drive motor round wire stator has large-scale production experience, can ensure the manufacturing stability and cost economy.

8327-1600 In addition to new energy vehicle electric drive products, Weiling auto parts also has a rich product matrix in the field of thermal management. For example, in 2022, the world’s first mass-produced 800V silicon carbide 12000rpm high-speed electric compressor, the first rotor electric compressor in the history of passenger cars, CO₂ electric compressor. In the chassis execution system, the EPS steering motor of Welling auto parts adopts six-phase redundant motor design to greatly improve the reliability and stability of the motor, fully meeting the needs of advanced assisted driving and intelligent driving, and the handfeel analog steering motor of Welling auto parts has large torque, sensitive response and high reliability, which can significantly improve the driving control experience. In addition, suspension air compressors meet high efficiency, large flow and low noise, enabling users to ride comfort.

At present, the automobile industry is accelerating the iteration in the direction of electrification, intelligence and low carbonization. The technological innovation of the new energy automobile industry is crucial for energy saving and emission reduction and improving the market penetration of new energy vehicles, so as to achieve the “double carbon” goal of the automobile industry. Midea Weiling auto parts will aim to create high standard, high performance and high reliability products. Supported by the research and development and manufacturing of the world’s five major R&D centers and the “Hefei + Anqing” dual bases, it contributes new momentum to the development of global green travel.
