Abstract
The paper presents comparative performances of different rotor structure synchronous reluctance motors used for electric traction in automotive application. The electrical machine under study in this paper is a synchronous reluctance machine (SynRM) with 8 poles and 48 slots. The study design has implemented two V and U shape flux barriers with 4 layers. Pure Synchronous Reluctance motors potentially operate at high speed due to a cost-effective rotor compared to PM and induction motors. In this paper, thermal simulation and mechanical stress was also investigated to evaluated flux bar or sizing of the radial ribs. The approach leads to an original positioning of the radial ribs able to preserve the performances of the motor at high operating speed enhancing the mechanical integrity of the rotor. Some significant contributions of this study are new 4U layer barrier rotor and mechanical stress of ribs and bridges at maximum speed.
