摘　　要：分析了电动飞机主推进永磁同步电动机振动产生的原因,给出了不同阶数力波作用下固有频率的表达式,利用有限元仿真软件分别对永磁同步电动机的定子与机壳和整机进行振动特性的仿真分析。通过分析可知,优化电机结构能够抑制电机振动,从而保证电动飞机动力系统的安全性。The reason for vibration of permanent magnet synchronous motor was analyzed and the expression of natural frequency under different orders force wave was calculated. The finite element analysis software was used to simulate and analyze the vibration characteristics for the stator and casing and the whole motor. Based on the analytical results, the structure of the motor is optimized to reduce the influence of vibration, which ensures the security of electric aircraft power system.
