Description
Summary:This paper proposes a novel high performance dual rotor flux-switching drum winding (DRFS-DW) machine. To achieve high torque density, the machine adopted the dual rotor topology to utilize two airgaps boosting torque, and drum winding to maximize the flux linkage. Performance of the drum winding in dual rotor machine was compared with conventional concentrated winding to show its superiority. For better description of high torque density of DRFS-DW machine, flux linkage difference of two different winding configuration for proposed machine was shown with the aid of magnetic equivalent circuit (MEC) and finite element method (FEM) analysis. Drum winding showed higher flux linkage difference, hence higher torque in same driving condition. The DRFS-DW machine was optimized for higher torque density and lower torque ripple. The optimized model was finally compared with conventional FSPMM and initial model to show the improved performance.
