Mobile WebSiteIf the electric car metaphor adult, then the battery is the blood, to provide power for the vehicle; electronic control system is the brain, command the various components to run; drive motor is the heart, the energy into kinetic energy, driving the vehicle to run.
Drive motor, as the electric car "three power" one of its important position is self-evident. China's drive motor industry, with the growth of the automotive industry, especially the promotion of new energy vehicles and rapid development and has made great progress.
It is understood that China's enterprises have independently developed various types of drive motor system products, the formation of the core competitiveness of the mass production capacity, but in product integration, reliability and core components applications, still with the international advanced level there is a gap.
In the wave of electric power, China's motor industry opportunities and challenges coexist. Based on the rapid development of new energy automotive industry, drive the future of motor suppliers in the market should not only meet the self-sufficiency, but also fully participate in international competition. How to further improve their competitiveness, occupy the global drive the motor industry and other highlands and other issues worthy of industry ponder, and put on the agenda.
■ The domestic market is self-sufficient
"At present, the domestic drive motor industry developed rapidly, the overall look can reach the international advanced level." The industry said that this is mainly reflected in two aspects: First, self-driven motor in the domestic market share is high, reaching 95% Can be done self-sufficiency; Second, China's overall performance of the motor, such as power density, efficiency and so can reach the international level, individual indicators of the performance better.
Related parties, the domestic drive motor, especially in the permanent magnet synchronous motor design and application level in the forefront of the world, and the market is also great. "It is understood that in 2016, China's new energy vehicle drive motor installed capacity of 59.5 million units, of which permanent magnet synchronous motor is the mainstream, installed capacity of more than 450,000 units, accounting for up to 76%. Domestic vehicle supporting the drive motor Most of them are from autonomous enterprises, and because of the richness of rare earth resources in China, permanent magnet synchronous motor has become the most important new energy vehicle drive motor in China.Currently, the existing automobile enterprises and traditional auto parts suppliers are involved in driving motor market, Professional motor enterprises.
■ Core components rely on imports
China's new energy automotive industry is booming, with this Dongfeng, driving the motor industry is expected to maintain steady growth. Although the progress of motor technology is obvious, but the core components rely on imports is a short board.
Insiders pointed out that the motor required corona insulation raw materials, high-speed bearings, high-precision position and temperature sensors, power electronics chips mainly rely on imports. For example, the controller's power electronic switch IGBT chip is almost 100% needed to be imported. At present, the drive motor power electronic switching components and control chip autonomy less than 10%.
Let the enterprise "Wang Yang sigh" IGBT is the core components of the motor drive system, in each acceleration and deceleration process plays a pivotal role. While the core components rely on imports to bring the direct problem is the high cost. In the motor system, the motor body and the controller of the basic cost of each half, if the controller in the power of electronic components can be made, the cost can be reduced a lot.
"China's drive motor application market is larger, the motor design capability is higher, but compared with well-known foreign companies, low level of manufacturing." Industry experts said, "Now many companies mass production drive motor or hand-based equipment Manufacturing capacity to be improved. "This led to the production of motor drive consistency and reliability can not be guaranteed, which is likely to directly affect the vehicle performance and user experience. "The reliability and production consistency of domestic motor products compared with the international advanced level, there is a certain gap.For driving the motor system, the vibration noise and electromagnetic compatibility aspects of the performance is also an important indicator of product performance.
■ should actively participate in international competition
With the global new energy automotive market started, drive the motor market also will grow. It is predicted that the global drive in 2020 the size of the motor market will reach 4.4 billion US dollars, the development of space is very broad. And efficient, integrated, lightweight, intelligent is recognized as the driving motor development trend.
"In the subsidy policy incentives, in recent years the market has emerged a lot of drive motor suppliers for new energy commercial vehicles, passenger cars, low-speed electric vehicle supply, but now more than 100 companies mixed, the gap is large "Industry insiders say that although China's leading motor industry leader has reached the world level, but the overall independence of the ability to have fewer enterprises to participate in global competition, the enterprise is minimal.
China's motor companies must improve the existing level, and actively participate in international competition. Enterprises should keep up with global development trends, take people long, make up the short. At present, we must first strengthen the automation of intellectual ability, improve product consistency and reliability. Government and industry should be aware of China in the motor technology research and development and industrialization of some short board, to increase efforts to support high-level drive motor and power electronic controller and the upstream industry chain development, encouragement can be gradually converted from subsidies to Tax cuts, so that outstanding suppliers come to the fore, the formation of the pyramid-shaped core components echelon.
