| Research Abstract |
This study presents a numerical modeling of vector (two-dimensional) magnetic properties considering hysteresis of silicon steel sheets. We define the magnetic reluctivity tensor newly and calculate them from the measurement data obtained by two-dimensional magnetic measurement. Our new modelings, which are "E＆S Model" and "E&S^2 Model", can be introduced into a finite element formulation for magnetic field analysis and can get the distribution of the magnetic field strength H-vector and the magnetic flux density B-vector.
In this study, two kinds of new modelings for vector magnetic properties for nonlinear iron loss analysis have been presented. We can analyze a three-phase transformer core model considering both the alternating and the rotating hysteresis. Moreover, it can be said that the presented methods are very useful to analyze electrical machines and apparatus considering vector magnetic properties.
