Abstract

The design and analysis of synchronous reluctance motor (SynRM) with a distributed type winding is an alternative to replace the permanent magnet synchronous motors (PMSM), which is commonly used in electric vehicle applications. The use of a SynRM eliminates the need for permanent magnets (PMs), reducing the dependence on rare earth materials and potentially lowering costs. In this paper, there are two approaches: a new approach of step-skewing rotor (SSR) is proposed to improve eletromagnetic parameters such as minimization of the active volume, maximization of the output power and reduction of the torque ripple of the SynRM. Then, a finite element technique is developed to analyse and simulate the distribution of magnetic flux and map efficiency of the proposed SynRM. Additionally, the paper has also investigated the distribution of temparature and machnical stress in the region of flux barries of the rotor.
