The study concerns with industrial low voltage three-phase induction motors, 4 pole, 50 Hz, 400 V, TEFC, in the 0.75–22 kW power range. The paper presents the results of a research project whose aim was the efficiency enhancement in industrial three-phase induction motors, making use die cast copper rotor cage and premium electrical steel. Induction motor is a veritable machine in the industries today, since is the most widely used electric motor in the industry. It offers a reasonable performance, manageable torque/speed characteristics and a better efficiency. The aim of this paper is to examine a comparative analysis of a threephase induction motor for performance evaluation. The computer simulation and experimental methods were used to carry out the investigations, validation and evaluation of the behavioural characteristics of the machine. The simulation and experimental results obtained were compared to validate the results obtained from the experimental method. It was shown that the results from the simulation and experimental methods were in agreement with the theoretical values of the three-phase induction motor. Thus, the results indicated that the relative errors were negligible and the proposed simulation models accurately predict the equivalent circuit parameters of the induction motor.
