Modeling the Effect of Cutting on the Magnetic Properties of Electrical Steel Sheets

Various approaches for modeling the degrading effect of cutting on the magnetic properties of electrical steel sheets have been proposed. They differ significantly with respect to their underlying concept, applicability, and need for measurements for parameter adjustment. In this paper, we propose a classification of the different models, study their differences, and analyze the respective implementation efforts. We hereby aim to provide a tool that enables the selection of the most suitable modeling approach for a given design task, taking the influence of the cutting into consideration.
