摘要：
We report an investigation and a theoretical assessment of power losses prediction in non-oriented silicon iron sheets (NO Fe Si) M800-65A industrial type, cut longitudinally and transversally to the rolling direction. The loss behaviour of this material was studied as function of frequency in the range of 5 Hz to 200 Hz at a given magnetic polarization (J) of 0.5 T and 1 T. Using the concept of loss separation for the data analysis, in the approximation of linear magnetization law and low frequency limit, it can be considered that the excess losses can be quantitatively assessed within the theoretical framework of the statistical loss model based on magnetic object theory.
