摘要
采用有限元法对永磁同步电动机的定子进行了模态仿真。通过对电机定子模型的合理简化,计算了电机定子在自由状态下的前7阶固有频率和相应的自由模态。然后通过模态试验,验证了有限元模型的准确性,为电动汽车电机的振动控制和NVH的改善提供了参考。
The stator of permanent magnet synchronous motor(PMSM)is simulated by finite element method.Through reasonable simplification of the stator model,the first seven natural frequencies and corresponding free modes of the stator are calculated.Then the accuracy of the finite element model is verified by modal test.It provides a theoretical basis for vibration control of electric vehicle motor and improvement of NVH.
