AB  - This study presents a theoretical study of the coupled magneto-elastic phenomena, with a view to modeling the vibratory behavior of squirrel cage asynchronous machine. A coupled model is developed to calculate the mechanical deformations of this machine in magnetic field. The  two equations governing magnetic and mechanical phenomena are solved using finite element method. The magnetic force distribution is calculated through a local application of virtual work principle. A spectral analysis of this force made it possible to determine the dynamic response of the stator for each harmonic force. This response has been calculated only after a modal analysis which could determine the resonance frequencies and its proper associated modes.
