Comparative Analysis of Double Stator Permanent Magnet Flux-Switching Machines with Segmented Inner Stator and Non-Segmented Inner Stator

Abstract

This paper examines and compares the analysis of double stator PMFSM between segmented and non-segmented inner stator. The analysis particularly focused on output performance of flux linkage, back-EMF, cogging torque, average torque at various armature current densities, speed and power characteristics which are investigated using JMAGDesigner ver. 14.0. The aim of analysis is to overview the suitable design for future electric transportation based on the characteristic of double stator PMFSM. Thus, the 2D finite element analysis (FEA) approach is used for preliminary analysis. Based on flux linkage analysis, the segmented design generates higher magnetic flux magnitude which is 40% higher than the non-segmented design. Moreover, the segmented design also achieved higher torque and power compared to the nonsegmented design with 35.54% and 32.06% different percentage, respectively. The results obtained show that the segmented design produces better performance compared to non-segmented in terms of torque and power.
