- The paper presents an algorithm for calculation of eddy current power losses caused by macroscopic eddy currents in ferromagnetic materials considering non-linearity of magnetization characteristics and magnetic hysteresis. The results of calculations are presented for a typical non-oriented steel sheet with silicon content of 6.5%. It has been found that inclusion of hysteresis loop and non-linearity of magnetization for the analyzed material has little effect on the calculated eddy current losses. Restrictions on the use of the algorithm are primarily due to the assumption of average values of the flux in the cross section of the sample, numerical problems when converting B → H and H → B for large increases in the induction, and the lack of regularity of the shape of the hysteresis loop measurements.
