|On-Site Speaker (Planned)
This talk will present several opportunities of application of additive manufacturing for the realisation of next generation electrical machines. Emphasis will be spent on the description of successful examples of Laser-Powder Bed Fusion (L-PBF) of iron cores (silicon steel), permanent magnets (NdFeB) and coil conductors (Cu) in a variety of machine topologies. While it is now clear that L-PBF presents unique advantages to design geometrically optimised components, it is proving challenging to reach adequate level of material performance. The talk will examine the typical challenges that the named materials pose to L-PBF processing. Taking the magnetic materials as an example, we will present our experience on how to combine laser parameters and alloy composition to develop desirable microstructures. The talk will then conclude by presenting aspects of the fabrication of Cu and multi-material assemblies (steel-Cu) with the use of a novel multi-beam L-PBF platform equipped with multi-material recoater.
