Silicon iron magnetic steel for electric motor fabricated using laser powder bed fusion process

Electric motors for electric cars and trucks are a critical component in the transportation industry. In this work, we focus on fabricating electric motor components, such as the stator core, using the laser powder bed fusion (L-PBF) additive manufacturing (AM) process. In order to determine the appropriate AM processing parameters, a series of small silicon iron (Fe-3.5%Si) cube samples is fabricated to evaluate the sample quality. The density of the samples is measured to examine the porosity levels. The cube samples are analyzed using SEM (Scanning Electron Microscope) and EDX (Energy-dispersive X-ray spectroscopy) to evaluate the samples' microstructure and compositions, thereby determining the optimal printing parameters for the silicon iron components.
