Abstract: Purpose: The purpose of this paper is to present the application of the loss approximation method for non-oriented electrical steel developed by the authors. A new model of a toroidal sample with dimensions ensuring high uniformity of the field was presented. Design/methodology/approach: A critical analysis of the methods used was carried out. Based on these considerations, the authors proposed their own loss approximation method, which allows obtaining high accuracy in a wide range of induction and frequency. The proposed method is based on the assumption that for a certain frequency range losses can be describe by two terms formula. For a fixed value of the peak flux density Bm, the graph of specific loss divided by the frequency should have the form of a straight line. Then, the obtained coefficients for different Bm are the basis for approximation with the power function. Findings: The comparison of measurement and approximation results shows that the method allows to obtain very good accuracy in a wide range of induction and frequency. Research limitations/implications: More detailed studies on the impact of cutting on a larger number of samples with different geometrical dimensions are needed. Practical implications: Application of the new method provides a better approximation of the curve of the loss and thus a more accurate calculation of the core loss in the electrical machines. Originality/value: The paper presents the application of the loss approximation method for non-oriented electrical steel developed by the authors. A new model of a toroidal sample with dimensions ensuring high uniformity of the field was presented. It is shown that the approximation introduced allows for high accuracy in a wide range of frequency and magnetic flux density. [ABSTRACT FROM AUTHOR]
