- Abstract
This paper presents a mathematical model to obtain a failure indicator of stator faults based on the negative sequence component of the electric current. The model can be used in online diagnosis systems to separate the effects of voltage unbalance factor and the constructive asymmetries of the machine. Results of the application of the model were validated trough laboratory tests made into a specially modified motor and results were applied to success diagnosis of two motors of higher electrical power. As a main result of the work, a low computational model was obtained to diagnose a quick evolution failure that can evolve quickly to a thermal collapse of the stator winding with consequent repair costs.
