Caracterização paramétrica e simulação de motores de indução.

Abstract

The basic concern this completion of course work (CCW) is to study the three-phase induction motor and the two-phase induction motor, both in permanent and transitional regime, and to realize the importance of this electrical equipment in everyday life. This study intends to determine the parameters of a circuit equivalent to an induction motor and to compare both types cited quickly in terms of certain variables as power, current, torque and performance. It was performed a theoretical foundation about induction machines considering the contributions of various authors and also practical activities with two induction motors. These practical activities consisted of the determination of the stator resistance, of the no-load test, of the blocked-rotor test and of the load test using Foucault’s brake. The main result obtained was the fact that the three-phase motor has higher torque than the twophase motor, although it also has higher power consumption. It was concluded that, basically, the parameterized equivalent circuit, that the power flow overview and the attention to electromagnetic operation offer a good understanding of the induction motor.
