This paper deals with the electro-mechanical design of a high-speed-high-power (HSHP) electric motor. The focusis twofold: both mechanical and electromagnetic aspects are of interest. The former regards holding forces in order to sustain the retaining sleeve, components stresses, and rotordynamic behaviour of the rotor assembly. The latter addresses eddy current losses arising in different rotor parts. Usually different physics involving rotor losses, mechanical and thermal stresses are treated separately or superficially analysed with rules of thumbs approaches.This work addresses the lack of a comprehensive more detailed design treating mechanics andelectromagnetic challenges together. The rotor under study is for an aerospace propulsion application known as Boundary-Layer-Ingestion (BLI).
