Abstract: Due to the obvious advantages of high power density, small volume and weight, and high working efficiency, high-speed motors have been paid more and more attention. An efficient and stable driving system is the key to give full play to the excellent performance of a high-speed motor. This paper mainly analyzed the difficulties of the high-speed motor driving technology from the aspects of control strategy, angle estimation and power topology design, and summarized the current research results at home and abroad. Then, the high-speed motor drive technology and its development trend were summarized and prospected.
