Abstract

The influence that manufacturing processes have on electrical steel properties is investigated. The investigation is carried out by considering changes in measured electromagnetic quantities and the changes to parameters of a physics-based hysteresis model. The parameters of an inverse Jiles-Atherton hysteresis model are identified using nonlinear least square method and compared with measured data from steel samples that have undergone different stages of manufacturing. The results of the study may be used as a first step to the inclusion of manufacturing effects in models of electromagnetic devices.
