Abstract :
The performance analysis of a faulted induction motor fed with a natural sampled pulse-width modulation (PWM) inverter is presented. Faults in both delta and star connections of the stator windings considered include open phase and backward phase connections. The influence of the zero-sequence current on the motor performance is taken into consideration. The average and pulsating torque components and the phase currents are predicted based on the fundamental component of the invertor output voltage. Current waveforms, etc., showing the influence of the harmonic-rich inverter output are also simulated
