| Abstract Scope |
The processing of soft magnetic materials enabled the advent of additive manufacturing in electro-mechanical engineering. For some years, the possibilities and limits of various additive manufacturing processes for the production of electric drives have been explored. This research project focuses on the development of new materials for permanent magnet rotors produced by laser beam melting (LBM). Due to high cooling rates and the elimination of reshaping post-processing steps, FeSi alloys with a significantly higher silicon content up to 9 wt.% can be processed by means of LBM, which leads to improved soft magnetic properties. FeSi with varying silicon contents as well as FeCo alloys have been printed, annealed and characterized. Validation of the materials is done by mechanical testing as well as analyzing the microstructure using SEM (EDX & EBSD) and STEM, and subsequently by determining the permeability, coercive field strength and saturation flux density using toroidal cores. |
