Multi-physics design of synchronous reluctance machine for high speed applications

This paper is focused on multi-physics (structural and electromagnetic) analysis of synchronous reluctance machine (SynRM). Rotor's construction of SynRM is designed to provide the best electromagnetic behavior of the machine. The number and shapes of flux barriers are chosen in order to maximize the machine's saliency ratio. However, at high rotational speeds due to high stress in the bridges, the rotor might be damaged. To prevent from braking the bridges, some additional ribs have to be introduced into rotor's construction. This modification affects electromagnetic properties of the machine, thus optimal construction of the rotor has to be found in terms of electromagnetic and structural behavior of the machine.
