- Field-circuit model of electric machine can be used for investigation of its structural components shape influence on operating characteristics. The high power induction motor model was applied to examine effects of rotor bar shape modification, consisting in replacement the trapezium shape bar with rectangular bar. Torque and current characteristics and characteristic quantity of start-up torque and current, maximum torque and critical slip were determined with field-circuit model. Electromagnetic torque, currents and rotational speed, as function of time during motor start, were determined also. The effect of rotor bar height change were examined in similar way. All rotor bar shape modifications were realized with constant cross-sectional area. The results confirm, that the exchange of bars in considered design will bring economic profits and won't cause significant deterioration of operating features.
