Summary on development of permanent magnet synchronous motor

摘要

Permanent Magnet Synchronous Motor(PMSM) has the advantages of small size, light weight, high power density, and have excellent dynamic response characteristics, which make them very suitable for high-speed applications. However, high-speed PMSMs have parametric variations, load disturbance and other issues. With the increasing applications of high-speed PMSM systems and the pursuit of high-performance motors, high- speed PMSMs and their drive control technologies have become a new hotspot in electrical field. This overview describes the advantages of permanent magnet synchronous motor, status of development of China and foreign permanent magnet synchronous motor, the development of permanent magnet synchronous motor technology and the future trend of permanent magnet synchronous motor. Provide a reference for people to better understand the current situation and development trend of permanent magnet synchronous motor generation.
