Design of a 50.000 rpm synchronous reluctance machine for an aeronautic diesel engine compressor

摘要

This document describes the design procedure followed to realize an high speed synchronous reluctance machine for aeronautical application. The attention is mainly focused on the rotor design that is the most critical part of any synchronous reluctance machine, in particular for high-speed applications. After a preliminary optimization of the rotor geometry, a multiphysical design that considered mechanical, thermal and electromagnetic properties was developed. The main steps of the design procedure together with an extensive analysis of the final design are presented here. The prototype has been realized and tested in order to validate the design procedure.
