| Résumé: | The reliability of electric drives and driven motors depends on the quality of the
power supply voltage especially in the critical industrial process. In this work, a theoretical
study of the effects of voltage unbalances, sags and swells on induction motor (IM) is
performed by using the conventional method based on the theory of symmetrical
components. For this study, MATLAB software program is developed for calculating currents,
torque, power losses, temperature rises and derating factor. Besides, experiments have
been carried out for obtaining currents, torque and power losses. An agreement that is found
between the theoretical predictions and experimental data allows us to take into
consideration the predicted derating factor |
