Magnetostrictive excitation of vibration in machines-a modal approach
The current state of wisdom in predicting electromagnetically-induced stator vibration and noise considers oscillatory radial forces acting in the airgap at the tips of stator teeth. The same oscillations in magnetic flux density which cause these forces also cause internal stresses in the magnetic iron and there is not a consensus as to the relative importance of these. This paper presents a method by which the importance of magnetostriction as a vibration-induction mechanism can be quantified.
