Josh HooleJoshua Hoole received the MEng and PhD degrees in aerospace engineering from the University of Bristol, Bristol, U.K., in 2016 and 2020, respectively. He is currently a Lecturer in Systems Engineering and a member of the Electrical Energy Management Group with the University of Bristol, Bristol, U.K. His research interests include the characterization of conductor lay and AC loss variability in electrical machine windings and the development of aerospace system usage profiles via real-time aircraft tracking.
Efficient high-integrity winding technologies for electric propulsion machines
Electrical machines for future aircraft propulsion will need to push the boundaries in power density without compromising reliability. Against sector technology roadmaps there are still significant improvements required and the desired power to weight, efficiency and integrity will not be achieved through incremental developments. This presentation will explore the potential of rethinking how we manufacture and design high-performance electrical machine windings. Examples of recent developments will be given, covering metal additive manufacturing, high-integrity insulation systems, the application of probabilistic design principles to the prediction of winding failure, and the use of composite materials to realize an air-gap winding stator.
