The Estimation Method Comparison of Iron Loss Coefficients through the Iron Loss Calculation
Journal of Electrical Engineering and Technology, 2013 A new calculation method for iron loss coefficients is proposed by using the Steinmetz equation from Epstein data. The hysteresis loss must have linear characteristic according to the frequency. However, the existing iron loss coefficients are defined by formula of frequency. In this case, the hysteresis loss has non-linear characteristics by frequency.
