Magnetic Properties of Soft Magnetic Powder Composites at Higher Frequencies in Comparison with Electrical Steels

摘要

To ensure a fair comparison of magnetic properties between electrical steels and SMC the measurements should be done on samples with a similar geometry. At a certain transition point of frequency the specific core losses of SMC become lower then those of electrical steels. Thus, the application of SMC instead of electrical steels in electrical machines operating at elevated frequencies can improve their efficiency.
