More than 30 million electric motors are sold every year in the world, in the last 20 years the appearance of more efficient electric motors resulted in the replacement of more than 70% of the old motors installed. New technologies are being presented by manufacturers as substitutes for the squirrel cage induction motor (SCIM). Given this scenario, studies should be carried out to analyze the performance of these motors in the same operating conditions to know their main advantages and drawbacks. This study presents a comparison of the performance of electric motors classes IE2, IE3 and IE4 in the presence of voltage unbalance (VU) with under and over voltage. Results show that not only the unbalance percentage present impacts the motor performance, but also the magnitudes of the voltages present. The VU also results in an increase in the harmonics present in each motor, mainly in the permanent magnet hybrid motor, which presents non-linear characteristics.

With development of power electronics and control Theories, the AC motor control becomes easier. So the AC motors are used instead of the DC motor in the drive applications. With this development, a several methods of control are invented. The field oriented control and direct torque control are from the best methods to control the drive systems. This paper is compared between the field oriented control and direct torque control to show the advantages and disadvantages of these methods of controls. This study discussed the effects of these methods of control on the total harmonic distortion of the current and torque ripples. This occurs through study the performance characteristics of the AC motor. The motor used in this study is an induction motor. This study is simulated through the MATLAB program.
