We show for the first time that Selective Laser Melting (SLM), a powder-based Additive Manufacturing technology, can offer an alternative route to produce functional silicon steel components for electromechanical applications. This is achieved thanks to the good soft magnetism of the processed parts (coercivity less than 20 A/m, maximum permeability of over 20000) and a Topology Optimization (TO)-based approach to component design. We propose an applicative example where the rotor core of an existing synchronous electrical machine has been redesigned by means of both TO and manufacturing considerations aimed at best exploiting the unparalleled design freedoms that the layer-wise nature of SLM makes possible. Results show that the combination of freeform design and good magnetic properties could potentially lead to the development of electrical machines characterised by improved torque density. This property could prove particularly attractive for applications where weight saving is important, i.e., in the automotive and aerospace sectors.
