Due to its favorable properties of low core loss and high saturation magnetic flux density, amorphous material is widely used as the core material of low and medium frequency transformers. However, its magnetostriction is much higher than that of grain-oriented sheet steel, a very common material for conventional transformers, resulting in high acoustic noises. This paper proposes a comprehensive model of magnetostriction in amorphous material based on the interdependence between magnetostriction and magnetization by combining the isotropic magnetostriction effect and Jiles-Atherton energy balance theory. Incorporated in coupled magneto-mechanical field calculation, the proposed model can correctly simulate the butterfly loops of magnetostriction, magnetic hysteresis loops and vibration displacements. The theoretical results of magnetostriction characteristic are verified by both single sheet test and the experimental results of amorphous transformer prototype.
