Magnetic Behavior and Loss Assessment of Additively Manufactured Fe-Si alloys

Abstract

This study deals with the production and characterization of soft magnetic materials produced by means of additive manufacturing technologies. In particular, the laser-powder bed fusion has been used developing different siliconiron alloys. The focus is to provide the BH magnetization trends, as well as the specific losses, for a wide range of supply frequency of a set of additively manufactured soft magnetic materials. Ad hoc specimens, including 'as build' and 'annealed' samples, have been tested in order to address the complete scenario about their applicability in advanced electrical machines. Consequently, the present document has to be considered as a reference where the readers that do not have the possibility to print or test soft AM materials can find useful data to start the designs and simulations of their own applications.
