Determination of Optimum Stator and Rotor Resistance Values for Obtaining Parameters of Three Phase Induction Motor by Taguchi Method

The aim of this study is to optimize the stator and rotor resistance parameters of a three-phase induction motor with known parameter values by using the Taguchi method. For this, 4 control parameters which are related to the motor power selected: utilization factor, magnetic flux density in the air gap, flux density shape factor depending on the magnetic saturation coefficient of the teeth, and the pole spacing. Experimental studies are performed using an L25 orthogonal array and the ideal combination of the induction motor's control factor levels is determined. Then, optimum parameters are determined by Taguchi method using MINITAB software. The stator and rotor resistance catalogue values are 0.0063 and 0.0083, respectively. These values are decreased to 0.004 and 0.0068 with this study. In addition, analysis of variance (ANOVA) is conducted in this study. ANOVA is a statistical technique for the verification of the optimal design parameters through confirmation experiments.
