Outline
With the increasing requirements for environmental protection, energy saving and emission reduction, higher requirements are also put forward for electric drive motors of new energy vehicles. High speed, high power density and high compactness have become the main goals of the development of electric drive technology for future vehicles. Among various types of motors, permanent magnet synchronous motors can take into account the requirements of high speed and high power density at the same time, but there are still difficulties in structural design, materials, processing, and cooling of high-speed permanent magnet synchronous motors that need to be overcome urgently. In this paper, the key technologies and development status of high-speed permanent magnet synchronous motors for automotive electric drives are expounded from the aspects of motor structure design, motor control and power devices with a brief analysis of the technical challenges faced by the current automotive high-speed drive motor system design. Last but not least, key issues in the research and development of high-speed motors, focusing on more compact structures, high-strength permanent magnet materials and more precise control, and prospects for the multi-physics and multi-disciplinary research and development of high-speed motors are illustrated.
