Investigation of the Effects of Unbalanced Voltages on the Performance of a Three-Phase Squirrel Cage Induction Motor using Finite Element Method

Induction motors are widely used in industrial, commercial and residential applications. An induction motor may exposed to the unbalanced voltage in the various operating conditions. Therefore, it is vital to investigate influences of voltage unbalance on performance of induction motors. In this paper, the performance of a three-phase squirrel cage  induction motor has been simulated using Finite Element Method(FEM) supplied by different unbalanced voltages with the same Voltage Unbalance Factor(VUF) as well as the same positive-sequence phase voltage components. In addition, power, losses and efficiency of the simulated motor under mentioned conditions have been studied.
