The paper analyses the induction squirrel cage motor type 5AZ 100LA-4 product of company Konačar. As a matter of fact two version of the same motor from Končar are analysed. The old one, known under commercial label 2AZ 155-4 and the new one, labelled as H5AZ100LA-4 (IE3 efficiency class). The computer model for calculating the parameters and operating characteristics is set in software program, based on the exact cross section of laminations of iron core from the producer. The motor is calculated on the base of these data, resulting in parameters and operating characteristics, obtained as output data from the computer model. First modification is realized by changing the number of conductors per stator slot and the length of the air gap. The improvement of efficiency from 78.4% to 78.8% is observed in the first optimized model with significant improvement of power factor from 0.8 to 0.85. Second step in motor optimization was to increase the slot fill factor. Therefore the stator slot was optimized i.e. changed which resulted in bigger slot fill factor and lower core saturation. Besides the stator slot modification, the stator outer diameter was increased as well as the motor length. The final optimized model has efficiency 86.5% and power factor of 0.87 at full load.H5AZ100LA-4 has efficiency of 86.8% and power factor of 0.76 at full load.
