The top three German companies will shift their focus to the field of electric vehicles in the next decade. In July, Volkswagen "2030 Strategy" released its mobile travel transformation strategy. BMW Group released its "Three-Step" transformation plan in March this year. And Mercedes Benz, as the pillar of Daimler, released its "Comprehensive Electrification" Strategy Conference in July. The development roadmap of the top three German companies in the next decade has been basically clear, and the competition has shifted from the field of fuel vehicles to the electric vehicles. In order to meet the requirements of EU Emission Regulations, at present, Volkswagen Group, BMW Group and Mercedes Benz have a large number of plug-in hybrid models, however, careful observation of the ten years’ planning of the three manufacturers shows that pure electric drive is their final choice.

Electrification has become the general trend of the development of automobile industry. At present, the competition situation of diversified players has just started. It is expected that the competition pattern will be more intense in 2025 with richer products and more mature technology. At the same time, the market-oriented survival of the fittest will officially begin.

From the application of electric drive system of new energy vehicles, "three in one" electric drive assembly scheme has become the mainstream. Under the "three in one" electric drive system, the motor, controller and reducer can share part of the shell to reduce the transmission parts. The benefits of this are obvious: reduce the weight and size of the system, and effectively improve the power density of the electric drive system. After the number of parts is reduced, the overall durability of the system is greatly improved, the NVH value of the system can be effectively controlled, the manufacturing cost can be reduced, and it is also conducive to the assembly and production of vehicle enterprises.

Compared with pure electric vehicles using single electric energy, hybrid electric vehicles use oil electric hybrid power system, and hybrid gearbox is a transmission system that couples the power of engine and driving motor in a certain way and can realize speed change and torque change.

As one of the core components of new energy vehicles (battery, motor and electronic control), the driving motor and its control system have a promising future!

The future market size of the new energy motor predicts that the global new energy motor market will reach 51 billion 700 million yuan by 2025, 3.5 times that of 2019.

Flat wire motor has the advantages of high power density and compact structure, which is in line with the future development trend of new energy vehicle motor. It is an innovative motor technology.

The manufacturing process of the motor is divided into flat wire motor and winding motor. The flat wire winding motor improves the motor slot full rate by using flat copper wire with larger cross-sectional area, which has the advantages of high power / torque density, high efficiency and better heat dissipation performance. At the same time, it is easier to realize automatic production and meet the requirements for high product consistency after the outbreak of the new energy passenger vehicle market.

1. Overcome the production capacity problem: the production capacity of the whole line is 30K / year, with a beat of 69s, which is twice the average level of the industry; The product excellence rate reached 99.5%, better than the industry average of 98%.

2. Intelligent hybrid production: flexible rotor assembly line, intelligent hybrid production, compatible with a variety of products with large size differences, forward-looking design, and production line design compatible with future models.

3. Advanced injection molding process: integrate the advanced injection molding process in Europe to ensure the consistency of rotor finished products and the stability of high-speed operation.

4. High automation level: the production line is unitized, and different types of robots are used for on-line production. The automation rate is as high as 80%, reaching the advanced level of the industry.

5. Informatization productivity: match the operation management system as the configuration tool to manage any production line configuration and formula for traceable parts and components to perform value-added work; Provide quality tracking service, power transmission system, machining process, global parts tracking system; The plant information system monitors all mass-produced industrial equipment and machines in real time.

6. People oriented combined with lean production: thanks to the high requirements of international well-known vehicle enterprises for safety and standardization, Liyuanheng has ensured that the robot operation area maintains a safe distance of ≥ 500mm from the surrounding fixed objects and equipment through multiple tests, comprehensively considering the utilization and safety of the site, realizes the line unit layout and greatly saves the site space.

Under the trend of "electric intelligence" and "carbon peak and carbon neutralization", Chinese parts have ushered in a historic opportunity to improve their position in the global industry. Especially at the great opportunity of the development of the "new four modernizations" of automobile, the automobile industry chain closely revolves around the innovative development of electrification and intelligence, strives to overcome the core technology, solve the "neck" problem, and accelerate the cross-border integration among industries.

Lyric will continue to deepen its advantageous fields, accelerate the iteration of product technology through industry university research cooperation, lead the industry in the development technology of flat wire motor, and realize the sustainable development strategy of product sales generation, R & D generation and pre research generation!
