Abstract
One of the key features of any electric machine is high efficiency, which in turn means keeping losses to a minimum. Recent advances in the field of additive manufacturing show that the addition of boron to binder jet printed iron silicon improves magnetic properties. However, there has been little success in reducing the eddy current losses at higher frequencies. In this work, the effect of boron particle size on total loss in binder jet printed iron silicon steel was evaluated. Both quasi-static and ac magnetic characterization were used to analyze the magnetic properties. Bulk resistivity is measured using four-probe method. Finally, the microstructure was analyzed using scanning electron microscopy to study the grain boundary as well as quantify the grain size and porosity.
