Abstract: The advantages of permanent magnet synchronous motor make it reach the requirements of energy saving and environmental protection in railway traction. As the PM motor technology is becoming mature, the PM motor is sure to be widely used in railway traction system in future. This article proposed a permanent magnet synchronous motor which has a new type of rotor structure. And then, set up static simulation system of the PM motor based on Ansyis, and dynamic simulation system based on Magnet. At last, got the dynamic and static characteristics of the PM motor in the method of finite element analysis. The article is meaningful for optimization of PM motors. The result established the theoretical foundation for designing and optimizing relative products.
