Abstract

This study investigates the characteristics of permanent magnet assisted synchronous reluctance motor (PMASynRM) using coupled FEM and Preisach modelling. The focus of this paper is the characteristics analysis of d, q axis inductance according to magnetizing direction and quantity of interior permanent magnet for PMASynRM. Investigation on nonlinear characteristic of the machine is performed by Preisach´s theory application. Comparisons are given with characteristics of normal synchronous reluctance motor (SynRM) and those according to the quantity of residual flux density (0.3 T and 0.4 T) in PMASynRM, respectively
