摘要

The accuracy of magnetostatic finite element simulations depends largely on the quality of the magnetization curves used to model ferromagnetic materials. Established measuring approaches either suffer from a time-consuming preparation of samples or a reduced accuracy in measuring the sample’s field strength. Therefore, a simulation-based approach was developed that replaces the problematic field strength measurement with a finite element simulation while maintaining a convenient sample geometry. The proposed method’s requirements and feasibility were discussed using a simple magnetic circuit. The method’s accuracy in determining a correct magnetization curve was shown on a closed simulation model using a known magnetization curve as reference. Influences of measurement and simulation errors were determined and compared with the typical simulation accuracies.
