Resumen:
A mathematical model of an induction motor including single-point bearing defects is proposed in this work. This model allows studying the behavior of different current-based fault diagnosis strategies in front of bearing faults. For this to be achieved, an eccentricity at bearing fault frequency is added to the model of a wound rotor induction motor. Through simulating this model, the effects of an outer race single-point defect on the motor variables are analyzed. Particularly, the behavior of the electromagnetic torque under fault condition is analyzed in this effort.
