摘　　要：准确计算异步电机定子的振动模态和固有频率是降低电机噪声和振动的基础,文章以某大中型异步电机定子铁心为研究对象,对其进行了有限元模态分析,研究了其固有振动特性;进行了定子铁心模态试验,与仿真结果进行对比,确定了定子铁心冲片等效弹性模量,为进一步的研究奠定了基础。Accurate calculation of vibration mode and natural frequency of induction motor stator is the basis of reduction of motor noise and vibration.Certain large-sized and medium-sized asynchronous motor stator core was employed to analyze the finite element mode ,to study its natural vibration characteristics, and get a variety of frequency and vibration modes of low order.By stator core modal test and comparison of simulation result, the elastic modulus was defined and will contribute to further study.
