Abstract :
The simulation of a three-phase induction motor drive system is presented with emphasis on the electrical faults of the inverter and induction motor. Using the basic components of MATLAB SIMULINK toolboxes, the drive system is modeled. An induction motor with mechanical faults is modeled using the winding function method (WFM) and is integrated with the drive model using S-function. The influence of the harmonics produced by synchronous or asynchronous PWM power converters on the induction motor stator current fault-related components is studied. The current waveform patterns for various modes of inverter device failures are investigated. It is shown that the stator current can be used for detection of electrical faults in either the induction motor or the inverter
