摘要: Magnetostriction in nonoriented (NO) electrical steel is a possible source of vibration and acoustic noise machines. The anisotropy the magnetostriction NO can be far greater than that its specific power loss which often quoted. Also under rotational magnetization much higher alternating magnetization. This paper shows relevance magnetostrictive to steel. An investigation effect was carried out, followed by measurements. A model based on an analogy mechanical elasticity used describe magnetostriction. Results show high value mainly driven transverse direction. phenomenon shown asymmetrical deformation back iron machine cores where flux predominates.
