RESUMO

This thesis presents a study about the steady state behavior of the three-phase induction motor. The validity of the use of the electric equivalent circuit is discussed when it is utilized on the rated conditions and also on any other operating conditions. No-load and the blocked rotor tests are performed on a three-phase induction motor for the determination of the equivalent circuit parameters. The tests run in variable load conditions in a usual interval of operation of the motor, in terms of slip, show that the equivalent circuit does not represent quit well the behavior of the machine when it works out of the rated point, because the parameters do not represent it in those operating condition any more. The magnitudes obtained in the variable load test are conditioned and used in the training of an artificial neural network Multi-Layer Perceptron (MLP). For the validation of the results, the neural model and experimental tests of the induction motor results are compared
