Numerical Approach Including the Winding Impact for Electrical Machine Vibration Analysis
Résumé
A numerical approach is presented to study and analyze the winding influence on the vibration problem of electrical machines. A multiscale homogenization method is developed to model the mechanical response of the winding structure, which is hard to be finely modeled. Associated with a magneto-mechanical formulation, this approach allows analyzing the mechanical deformation and vibration problem of electrical devices. The computational method has been applied to the magneto-mechanical analysis of a switched reluctance machine. The results show the importance of considering the windings in the vibration analysis of electrical machines.
