Accurate calculation of vibration mode and natural frequency of induction motor stator is the basis of re-duction 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.
