In recent years, the application of foreign wheel hub motor drive technology is mainly reflected in two aspects: one is the integrated electric system developed by the R&D team represented by the tire manufacturer or the auto parts manufacturer; the other is the vehicle manufacturer and the hub motor Electric vehicles jointly developed by drive system manufacturers. In China, the research on wheel hub motors is mostly concentrated in colleges and universities. The products are all electric vehicles. At the same time, independent brand car manufacturers have also launched their own wheel motor technology products. Although domestic automakers can produce electric cars, The research on the driving technology of the hub motor is not mature, especially in the development of high torque hub motor, there is still a certain gap with foreign advanced products. Therefore, China still needs to strengthen the research and development investment in the wheel motor technology, improve the core competitiveness and reduce The gap is to reach the world's advanced level.
