An accurate structural simulation model is necessary for the prediction of each dominant modal frequency of stator vibration in electrical machines. Material properties such as: mass density, Poisson's ratio and Young's modulus play an important role of the modal frequencies as well as the machine's structure and design. Owing to the changing properties of material during manufacturing processes of the stator lamination core and varnished windings, it is difficult to determine the exact values of Young's moduli of the stator lamination core and coil windings. In contrast, the Young's modulus of solid component parts, such as motor frame and end-covers, can be found from manufacturing data sheets. In this paper, the techniques for the Young's modulus estimation of the stator lamination core and coil winding were presented. A Semi-Finite Element Method technique has also been developed for calculation of the Young's modulus of the lamination core materials.
