Induction motors are robust machines used not only for general purposes, but also in hazardous locations and severe environments. Although these are very reliable, they are susceptible to many types of faults. However, induction motor drive faults can be detected in an early stage, in order to prevent the complete failure of the motor drive and ward off unexpected production costs. In this paper, a simple diagnostic and detection method that allows the real-time detection and localization of single and multiple open-circuit faults in the voltage source inverter (VSI) for a three-phase induction motor drive system using just the motor phase currents, is presented. A model of the system is built using MATLAB/SIMULINK. Simulation results are presented showing the diagnostic method performance under distinct operating conditions. |
