Rotor design on torque ripple reduction for a synchronous reluctance motor with concentrated winding using response surface methodology

This paper deals with the optimum rotor design solution on torque ripple reduction for a synchronous reluctance motor (SynRM) with concentrated winding using response surface methodology (RSM). The RSM has been achieved to use the experimental design method in combination with finite element method (FEM) and well adapted to make analytical model for a complex problem considering a lot of interaction of design variables. Comparisons are given with characteristics of a SynRM according to flux barrier number, flux barrier width variation, respectively.
