Drive motor performance and gap coexist
Core Tip: China's new energy vehicles do not have a 60-year history like traditional cars, but in recent years, they have made great progress. Especially after China has listed new energy vehicles as seven strategic emerging industries, the technical route has become clear. Established the development route of “three horizontals and three verticals”. “Three horizontals” refers to multi-energy powertrain control systems, motors and their control systems, batteries and their management systems, which are commonly referred to as batteries, motors and electronic controls. What is the development of China's drive motors?

According to reports, in recent years, the research and development team of the electric vehicle motor drive technology of the Institute of Electrical Engineering of the Chinese Academy of Sciences has achieved many results. In the aspect of high power density permanent magnet motor drive technology, the optimal design method of permanent magnet motor for vehicle based on design plane theory is proposed innovatively, which solves the problem of the lack of optimization theory and special design software for vehicle motor; The low-stray inductor power main loop design method and the high-efficiency water-cooled radiator design method solve the key technical problems of the vehicle controller high power density design. In the high-performance control of permanent magnet motor for vehicles, a current-sliding mode control method based on internal model is proposed to improve the torque response performance of the motor drive system. The research and development results of the Institute of Electrical Engineering are widely used in the “Ten Cities and Thousand Vehicles” demonstration of new energy vehicles and the transformation of Hong Kong's electric trains, and won the first prize of the 2012 China Electrotechnical Society Science and Technology Award.
