Abstract

The paper unveils the relative influence of design changes in the angle of taper of the 3ph squirrel cage induction motor rotor bar cross section, on the starting torque of the machine. The influence of the barcross sectional area (CSA), top width and the radial depth of the bar section, as established design variables, were also investigated so as to know where the degree of influence of the taper angle falls in comparison, as far as the starting torque is concerned.The machines were investigated in their steady state operating mode using the equivalent circuit method.The machine learning capabilities of the Least Square Support Vector Machine (LSSVM) was deployed to extract by prediction, information about the likely dependencies between the randomized block of the geometric variables and the Starting torque,and the captured information was stored using the Root Mean Square Error (RMSE) of predictions. The validated results show that the leakage reactance and resistance of the rotor tends to be significantly sensitive to a design change in the taper angle of the transverse section of the rotor bar.
