| Abstract: | Based on the study of the characteristic of laminated cylinders, the in-plane vibrational behavior of electrical machine stators is presented in this paper. The Lagrange equation is used to establish the equation of motion. The frequencies of the fundamental vibrational modes are extracted from the corresponding frequency equation. In order to verify the validity of the calculations, experiments are performed on the actual electrical machine stators. The analysis can be used at the design stage to predict the natural frequencies of electrical machine stators. |
