Main Problems Existing in the Motor Drive Motor and Its Controller in China

(1) R & D capability of motor raw materials and controller core components is weak, depending on imports, such as silicon steel sheet, high-speed motor bearings, position / speed sensor, IGBT module and so on. High cost of imported products, affecting the industrialization of motor systems. (2) China's motor vehicle electrical and mechanical integration level with the larger gap between foreign countries. Controller integration is low, volume, weight is relatively large. (3) China's automotive motor system is still in its infancy, the level of manufacturing technology behind the lack of automated production lines, resulting in product reliability, consistency is poor. The industrialization is smaller and the cost is higher. (4) At the present stage, there are fewer national standards for electric motor drive motors and are not perfect. Such as: different types of motor systems using the same testing standards, the lack of reliability, durability evaluation methods.
