Improvement of the E&SS modeling considering phase correction for the field analysis considering two‐dimensional vector magnetic properties

Abstract

SUMMARYThe two-dimensional vector magnetic properties are proposed as a method to express the magnetic anisotropy and iron loss precisely by using the relationship between the flux density vector and the magnetic field strength vector. The E&S modeling [6] and the E&SS modeling [7][8][9] have enabled the representation of the two-dimensional vector magnetic properties in FEM calculations. However, the calculated flux density waveform at each element has a phase difference depending on the excitation condition. In this paper, we have improved the E&SS modeling to solve the magnetic field problems under any exciting condition.
