This paper presents an iron loss calculation by incorporating the Landau-Lifshitz-Gilbert (LLG) equation into a magnetic circuit model. In the proposed model, dc hysteresis loss is calculated by the LLG equation, and eddy current loss is calculated by a magnetic inductance. The validity is proved by comparing with the catalog values.
This paper presents a novel magnetic circuit model incorporating micromagnetic simulation. The proposed magnetic circuit model consists of two elements; one is a dc hysteresis element given by the micromagnetic simulation, the other is an inductance element which denotes eddy current loss in silicon steels. In addition, the proposed model can be coupled with an external electric circuit model. The...
