Comparison between conventional and loss d-q model of PMSM

Abstract

This paper presents the dynamic d-q `loss model' of PMSM wherein the core saturation has been taken into account. Modeling equations of conventional and `loss model' have been presented. Field oriented control strategy with conventional zero d-axis current control has been used to control the PMSM so as to compare the conventional and `loss model' of PMSM through detailed computer simulations. The results of these simulations show that dynamic performance of the drive is affected by the inclusion of core loss resistance.
