要約(英語): This paper discusses modeling of magnetization curves in non-oriented electrical steel sheet. Initial curve and hysteresis loop under 0.15 T are approximately modeled as Rayleigh model, and Rayleigh loop constants are nearly proportional to crystalline grain size. Hysteresis loops more than 0.15 T under magnetization rotation region are represented by Preisach model, grain size distribution and RD easy axis. Magnetization curves over 10 kA/m are calculated with magnetization rotation model. However, magnetization curves modeling is necessary between domain displacement model and magnetization rotation regions. Magnetization curves in this region are modeled considering field component BN where B is flux density and N is the order of flux density and about 15.
