Abstract

Recently more and more attention has been paid to the application of flux weakening of a permanent magnet synchronous machine (PMSM). In this paper, many rotor configurations of the PMSM that are suitable for flux weakening operation were reviewed. A new stator design with shunt teeth has been studied by magnetic circuit analysis and finite element analysis. The new design and the conventional design have been compared and discussed. The validity and feasibility of the new design with a high flux weakening capability were verified by analytical and experimental results. Its predicted that the constant power speed ratio (CPSR) was as high as 9.5:1. The presented stator configuration would be a better solution for PMSM achieving a wide constant power speed range.
