SUMMARY:

Three-phase induction motors are crucial in advancing industrial technology and are responsible for a large portion of electrical energy consumption in this sector. Understanding the performance of these electrical machines when operated by frequency converters is essential for students, professionals, and researchers who work with this type of motor. In this context, this work presents a study on the performance of three-phase induction motors, considering pre-established variations in the frequency and voltage of the supply signal. Through the tests carried out and the data obtained, it was possible to analyze the behavior of the engine's performance and parameters under these conditions of frequency and voltage variation. It was necessary to develop electronic circuits for the inverter, using the IRAMX16UP60A integrated circuit, as well as a conditioning circuit based on Hall effect transducers. The tests were carried out, and the corresponding calculations were applied to determine the parameters of the tested engine. The results were presented in tables describing each frequency and voltage situation, and graphs were drawn based on these experimental data. Finally, the results provide a better understanding of the behavior of the three-phase induction motor in these specific conditions, highlighting the importance of the appropriate selection of frequency and voltage to optimize the motor's performance and guarantee its energy efficiency.
