Abstract
The magnetic properties of non-oriented electrical steels (NOESs) are characterized using an analytical simulation method accounting for the microstructures in ferromagnetic materials. Complementary experimental data for thin sheet laminations, obtained using a standard single strip tester (SST), are employed with the hysteresis mechanism investigated in terms of the measurement system and Weiss Mean Field effects. It is shown that the magnetic hysteresis loops of NOESs of 3% SiFe can be generated with remarkable accuracy for a broad range of magnetization frequencies and peak flux densities. The simulation method is also suitable for performing an energy loss analysis with calculated energy losses, when compared to corresponding measured data, showing a strikingly accurate match with, in most cases, an error of less than 1%.
