Loss Calculation of Magnetic Steel Sheet based on the Magductance

In order to accurately calculate the loss inside the laminated core, the hysteresis characteristics and loss characteristics inside the silicon steel sheet are measured based on the Epstein frame experiment. Based on the vector magnetic circuit model, the hysteresis characteristics within the silicon steel sheet are analyzed, and the hysteresis loops are mathematically characterized using the principle of magductance, and the experimental results are consistent with the calculation results.
