Optimization and Comparison of Optimal saliency Permanent Magnet Synchronous Machines for Electric Vehicle Application
Abstract
For electric vehicles' traction, Permanent Magnet Synchronous Machines (PMSM) are interesting because of their high power density and their efficiency on a large flux weakening range. This solution offers multi-possibilities of conception. As a matter of fact, it is possible to choose surface or saliency PMSMs, this last one could be dissociate into two groups: Normal-Saliency PMSM and Inverse-Saliency PMSM. Based on a typical working cycle of electric vehicles, we will compare optimal Normal-Saliency PMSM and Inverse-Saliency PMSM performances.
