Abstract:	摘要： This paper investigates the magnetic properties of an Fe-based amorphous material Metglas 2605 SA1, HB1, and a new high-induction HB1-M amorphous material. One of the core structures, with hybrid thin-film materials, is constructed. Different core types in the constructive modeling and the magnetic field simulation are studied by finite-element analysis. Results suggest that a long and straight core leg for a multiangled core can reduce the magnetostriction (MS) variation, where the number of multicored corners is an important factor in the reduction of MS variation and can improve the magnetic property. The magnetism of the triangular core is significantly better than that of the multisharp-angled core structure. In addition, a hybrid-type core structure with HB1-M is used for both improving the magnetic properties and reducing the magnetic loss. However, the magnetism in terms of sound level and core vibration is shown to be difficult to control. 其他題名： TMAG 出版者： New York: IEEE 出版日期： 2015-11 出處： IEEE transactions on magnetics, 2015-11, Vol.51 (11), p.1-4 資源來源： IEEE Electronic Library (IEL) 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
