Optimum design criteria for maximum torque density & minimum torque ripple of flux switching motor using response surface methodology

Abstract

This paper deals with optimum design criteria for maximum torque density & minimum torque ripple of Flux Switching Motor (FSM) using response surface methodology (RSM) & finite element method (FEM). The focus of this paper is to find a design solution through the comparison of torque density and torque ripple according to rotor shape variations. And then, a central composite design (CCD) mixed resolution is introduced, and analysis of variance (ANOVA) is conducted to determine the significance of the fitted regression model. The proposed procedure allows to define the rotor dimensions starting from an existing motor or a preliminary design.
