Abstract
This study investigates key technologies and development trends for the motor drive system of new energy vehicles, including power semiconductor devices and their packaging, smart gate drivers, and the device-based system integration design, for the drive controllers; it also explores new motor technologies related to the hair-pin winding, multiphase permanent motor, and permanent magnet synchronous reluctance motor. The study emphatically presents the development trends of the motor drive technologies for vehicles, and points out that permanent magnet synchronous motors will remain the main-stream drive motors in the new energy vehicle market within the next 10 years. Meanwhile, this study reveals several key issues existing in drive motor development, which could offer a reference for the technology development of new energy vehicles in China.
