Vibrations of Rotating Electrical Machines due to Magneto-Mechanical Coupling and Magnetostriction

摘要

This paper presents a method to calculate the vibrations of rotating electrical machines when the magnetostriction and the magneto-mechanical coupling are of interest. The method is applied to two kinds of machines (cage induction and synchronous machine). Moreover the method is experimentally validated with a special device. The results of the computations show that the magnetostriction affects the vibrations of both machines while the magneto-mechanical coupling is considerable only in large stators.
