| Abstract: | In this paper,based on the drive motors of electrical vehicles used in the World Exposition,the FEM model of the motor stator assembly was established with ANSYS software.And the model was confirmed by an experiment.Then the paper conducted a modal analysis of the stator with the software and obtained the mode shapes and frequencies.Moreover,a further study of the effects of stator components on the stator vibratory behaviors was conducted.And by comparison and contrasts,the paper made a detailed analysis on the changes of mode shapes and frequencies of the stator with different components.The work in this paper is helpful for further optimal design of the motor. |
