要約(英語): The assembled domain structure model (ADSM) is a multiscale magnetization model to simulate the magnetic properties of a core material. To physically represent the pinning type hysteresis using the ADSM, this paper develops a pinning field model formulated from on the microscopic distribution of pinning strength. Two methods are presented to implement the derived pinning field model in the ADSM. One represents the vector pinning field using the vector stop model, which depend on the magnetization vector. The other directly relates the domain-wall motion to the pinning field. The magnetization curves and hysteresis losses of a non-oriented (NO) silicon steel sheet are accurately reconstructed by these models.
