| Research Abstract |
Accurate isotropic and anisotropic vector hysteresis models have been developed to represent magnetic properties of silicon steel sheets. Efficient methods for electromagnetic field analysis have been developed using the hysteresis model above and homogenization technique for laminated iron-cores. A domain structure model was improved to describe mesoscopic magnetization process. A method for micromagnetic simulation has been developed under periodic boundary condition.
