A new modeling of vector magnetic properties for magnetic field analysis

This paper presents a new modeling of vector magnetic properties in an arbitrary direction considering alternating hysteresis of grain-oriented silicon steel sheets. We define the reluctivities in a new way, calculating from data obtained by two-dimensional magnetic measurement. Moreover, our new expression is introduced into a finite element formulation, and is applied to a simple anisotropic magnetic field problem. As a result, it is shown that our expression is applicable generally to anisotropic problems considering the hysteresis phenomena.
