ANALYSIS OF THE CUTTING AREA OBTAINED THROUGH MECHANICAL AND ELECTRICAL DISCHARGE TEHNOLOGIES IN NON ORIENTED SILICON IRON SHEETS

摘要: The practical application of low energy loss steels and an optimal magnetic core design are important, to minimize the losses in electrical machines. It is great importance reduce deterioration properties, during fabrication process. influence cutting area on was studied it can be concluded, that strongly influenced by technologies. There were tested sheet samples M400-65A industrial steel grade (thickness 0.65 mm), cut through mechanical discharge All have length equal 300 mm width 30, 15, 10, 7.5 5 mm. characterization performed using a Brockhaus measurement unit, which make measurements with × 30 2 . In order standard mm, there put together side 2, 3, 4 6 pieces different widths. properties analyzed at 250 mT, 500 1000 mT 1500 frequency range 10 ÷ 200 Hz.
