Optimum design for premium 250 kW efficiency of traction induction motor using response surface methodology & FEM

This paper deals with the optimum design criteria for the premium efficiency of 250kW traction induction motor, using response surface methodology (RSM) & finite element method (FEM). The focus of this paper is found firstly a design solution through the comparison of torque according to rotor bar shape, rotor dimensions variations and, secondly, a mixed resolution with central composite design (CCD) is introduced and analysis of variance (ANOVA) is conducted to determine the significance of the fitted regression model The proposed procedure allows to be optimized the rotor copper bar shape, rotor slot, rotor dimensions starting from an existing motor or a preliminary design.
