This paper deals with the challenge of designing a high-speed permanent-magnet synchronous machine (PMSM) with a continuous power of 700 kW as a turbo generator for the usage in aircrafts. For this application, high-power density above 5kW/kg is required. To identify the best topology and to fulfil the given requirements, various design solutions for the PMSM are taken into account. This contains various six-phase winding configurations to minimize losses or weight. Moreover, a possible magnet and various sleeve materials are taken into account in order to ensure mechanical stability. Furthermore, a thermal design is presented. Results given are based on analytical, as well as FE simulations.
