Hairpin Motor is Becoming the Outlet For The Development of the New Energy Drive Motor Industry
At present, there is insufficient awareness of flat wire drive motors in the market. From the perspective of international applications, the demand for hairpin motor by automobile manufacturer and motor manufacturers has emerged, and the demand for hairpin motor by automobile manufacturers is increasing.
At present, only a few domestic manufacturers have shipped them. Hairpin motor are becoming the core product of the new energy drive motor industry due to their advantages of high power density, low cost, and good temperature performance. However, due to the high barriers to equipment, technology and materials, it restricts the widespread use of new energy vehicles. The hairpin motor industry is currently a direction that is very worthy of market research and investment. The advantages of hairpin motor include the following:
1. Under the same power condition, the volume is smaller, the material is less, and the cost is lower.
2. Better temperature performance.
3. Lower electromagnetic noise.
4. Save copper, save costs, and improve efficiency.
According to the research results of Dongxing securities, the future development of the hairpin motor industry is divided into three stages.
The first stage: from 2018 to 2020, the penetration rate in the field of new energy passenger vehicles will reach 50%.
Marketspace: Assuming that in 2020, the hairpin motor will achieve 50% penetration in the annual sales of new energy passenger vehicle drive motors in China. According to the estimation of 1.6 million new energy passenger vehicles in 2020, the domestic demand for 800,000 hairpin motors is assumed. The unit price is 3,500 yuan, and the market size is close to 3 billion yuan. Calculated based on a 10% net interest rate, it corresponds to a net profit of 300 million yuan in the industry.
The second stage: 2021-2022, the penetration rate in the field of new energy passenger vehicles will reach 90%.
Marketspace: Assuming that in 2022, the hairpin motor will achieve 90% penetration in the annual sales of passenger car drive motors. According to the estimated sales of 3.2 million new energy passenger vehicles in 2022, the demand will be 2.88 million sets. The assumed unit price is 3,000 yuan, and the market size is Nearly 9 billion yuan, based on a 10% net interest rate, which corresponds to a net profit of 900 million yuan in the industry.
The third stage: After 2023, the market share of new energy passenger vehicles will be close to 100%, and at the same time, it will gradually penetrate into the field of logistics vehicles and passenger vehicles, and the market scale will continue to rise.
The market for motor companies comes from three aspects: one is its past technology and production precipitation, the other is the accurate prediction of future trends, and the third is the determination to lead the industry in execution.

From November 22 to 24, 2023, a motor industry event will be held at the Shanghai New International Expo Center, which is the much-anticipated "2023 China International 27th Small Motor Technology, Magnetic Materials Technical Seminar and Exhibition".
As one of the core parts of new energy vehicles, the electric drive system has an important impact on the performance of new energy vehicles, and has important significance for the power, economy, comfort, safety, reliability, and durability of new energy vehicles. In addition, in terms of industry needs, low cost, miniaturization, and intelligence are the main trends. The electric drive system of an electric vehicle is mainly composed of four parts: drive motor, transmission, power converter and controller. The drive motor is the core of the electric drive system, and its performance and efficiency directly affect the performance of electric vehicles. The size and weight of the drive motor and transmission will also affect the overall efficiency of the vehicle. Power converters and controllers can help electric vehicles operate safely and reliably.
In the long term, the trend of flat wire motors is highly certain. In the first half of 2021, the penetration rate of flat wire motors among the top 15 vehicle models in terms of sales reached 28%, compared to just 14% in 2020. It is anticipated that by 2025, the proportion of flat wire motors in the drive systems of new energy vehicles will exceed 80%.
X-Pin motor technology allows for a reduction in the height of the linear segment at the end of the motor while maintaining a high slot fill factor. This results in a shorter overall motor length, saving copper wire usage and improving motor efficiency, thus achieving miniaturization.
In recent years, the market penetration of new energy passenger vehicles has continued to rise. Due to the high demand, existing cylindrical-wire motors have become insufficient in meeting the performance requirements of electric vehicle propulsion. Therefore, the substitution of flat-wire motors for cylindrical-wire motors is a highly certain trend for the future. Motor manufacturers are actively seeking high-capacity, high-quality production processes to meet market demands, with ongoing optimization and innovation in the manufacturing processes of flat-wire motor stators.
As is well known, the energy conversion efficiency of electric motors is around 90%, meaning that losses account for approximately 10%. Within the energy losses of a motor, copper loss, which is the heat generated by the current passing through the stator winding, constitutes about two-thirds of these losses.By adopting flat wire motors, the round wire windings are replaced with flat wire windings, increasing the amount of copper per unit area on the stator. This increases the copper fill factor to 20% to 30%, meaning more copper is packed into the stator slots. This effectively reduces winding resistance, and the lower the resistance of the winding, the higher the electrical efficiency. Consequently, it reduces copper losses.
