Saturation and cross-saturation in synchronous reluctance machines

Abstract

The present paper gives an overview on the influence of the saturation and cross-saturation on the machine parameters and on the evaluation of SynRM drives performances. A SynRM with optimized flux-barriers shapes and a Permanent Magnet (PM) assisted SynRM will be considered for analysis. A comprehensive analysis of the variation of d- and q-axis fluxes, as well as several modeling approaches are presented in order to evaluate the influence of saturation and cross-saturation on the behavior of the two machines.
