Resumen:
Effects of rotor faults on stator currents in induction motors are studied in the present work. Particularly, the effects of such faults on the sidebands at fundamental and harmonics current components are analyzed. A multiple-coupled circuit model determines the variation of amplitude of these sidebands as a function of the number of broken bars, load and motor-load inertia. The results obtained from this analysis allow improving the rotor fault diagnosis techniques and identifying and separating rotor faults from others. Simulation and experimental results are presented to validate the proposal.
