Abstract :
This article considers the effects of open-circuited phase windings and of shorted coil turns of the stator winding on the operation of the induction machine. The analysis and comparison of faulted modes of operation is achieved by simulation, using the dynamic mesh reluctance model (DMRM) approach. The DMRM approach gives valuable insight of induction motor detection of the faulted windings. Clearly, five-phase motors with third harmonic control give the best performance for machines with one-phase open circuit, and careful machine design can minimize adverse effects of torque ripple
