Determination of Specific Losses in Stator Core of Electromechanical Energy Converter

[摘要] The purpose of this paper is the experimental research of the magnetic losses in electrical steels, soft magnetic alloys and amorphous alloys in the wide range of the magnetization reversal frequency and magnetic induction. The comparison between different analytical calculation methods of the stator-core specific losses is presented. The article shows that the known methods with the sufficient accuracy allows the stator-core-specific-loss calculation at frequencies below 400 Hz. However, the discrepancy with the calculations of losses by the different methods at the higher frequencies (above 400 Hz) can reach 2 times. The experimental research at high frequencies showed the 2-3-time discrepancy between the calculated and experimental data.
