Abstract
Magnetic properties of additively manufactured soft ferromagnetic non-laminated material is investigated and its DC magnetic losses determined. Ring samples from 4% silicon content electrical steel powder are prepared with a selective laser melting system. Sample hysteresis losses are determined experimentally with quasi-static measurements at 25 mHz magnetization frequency. Material hysteresis power losses ranged from 0.925 W/kg (1T, 50 Hz) and 2. S5W/kg(1.5T, 50 Hz) W/kg. Additionally, the results are compared with hysteresis losses obtained though the extrapolation of losses data measured at higher frequencies of 1, 10, 30 and 50 Hz. Correlation between the quasi-static and extrapolated results is obtained below the knee-point of the material, at 0.8 T and 1 T. The results are compared to other conventional electrical steel and 3D printed materials.
