Alexander Goodall

Dr Alexander Goodall is a lecturer in mechanical engineering design at the University of Edinburgh, conducting research into additive manufacturing of functional materials for use in high power density electrical machines. His interests vary from fundamental material process-property relationships to the optimization of electrical machine architecture and topology, spanning a broad cross-discipline scope. The majority of his work focuses of soft magnetic materials, however, future work focuses also on conductive materials. Goodall completed his PhD at the University of Sheffield, after 5 years of experience as a design engineer in the automotive industry.

Presentation

Additive manufacturing of 3D magnetic circuits

Additive manufacturing has been revolutionary in enabling complex structural components, however, the utilization of functional materials such as soft-magnetic materials is relatively immature. 3D magnetic circuits in electrical machines have been elusive due to the high eddy current losses caused by thick cross-sections in bulk material, and the inability to process electrical steel laminations into 3D structures. By processing soft magnetic materials with additive manufacturing, geometry can be tailored to avoid thick cross-sections and reduce eddy currents whilst maintaining a 3D magnetic circuit, enabling new machine architectures that can meet the power density targets for the electrification of aviation.
