Abstract :
This paper presents theoretical and experimental analysis of the voltage unbalance effects in a three-phase induction motor. A theoretical background about the TIM´s per-phase equivalent circuit for each sequence voltage component will be presented. After, will be shown the equations development for calculating torque and efficiency. The experimental results involve the application in laboratory of four data banks, totaling 2000 conditions, to understand torque and efficiency behavior.
