The aim of this article is to present an approach to the analysis of the phenomena of magnetization of materials in a rotating magnetic field. This approach is based on examination of the rotating vectors, specifically on the time variation of the moduli of vectors of the magnetic field strength $H$ and the magnetic flux density $B$ , as well as on time variation of their angles during rotation and the lead/lag between them. For the first time, the power loss separation based on Bertotti’s statistical model under rotational magnetization is represented completely in the time domain. The main benefit of the presented analysis is the observation of time variation of power loss components, especially excess power loss and the corresponding excess magnetic field in the material. Two typical electrical steels are analyzed: conventional grain-oriented M140-27 (CGO) and non-oriented M400-50A (NO).

基于矢量分析的 CGO 和无电工钢旋转损耗分量在时域中的分离

本文的目的是提出一种分析旋转磁场中材料磁化现象的方法。这种方法基于对旋转矢量的检查，特别是基于磁场强度矢量模量的时间变化 $H$ 和磁通密度 $B$ ，以及它们在旋转过程中角度的时间变化以及它们之间的超前/滞后。首次在旋转磁化下基于 Bertotti 统计模型的功率损耗分离在时域中得到完整表示。所提出分析的主要好处是观察功率损耗分量的时间变化，特别是超功率损耗和材料中相应的超强磁场。分析了两种典型的电工钢：常规晶粒取向的 M140-27 (CGO) 和非取向的 M400-50A (NO)。
