In this work, a low-frequency dynamic hysteresis model is proposed and applied to nonoriented Fe-Si steel. The model based on Preisach theory can be used when skin effect is negligible over the lamination thickness. In our model, the Preisach engine that usually takes the magnetic field as input variable must be inverted. Some B(H) symmetric loops are calculated and compared with measurements in the rolling direction both in quasistatic and dynamic operations under sinusoidal induction.
