The study of the potential impact under the typically measured signals in electrical machines due to faults is a crucial step for the development of effective systems for fault detection. The relationship between the electrical and mechanical components has been extensively studied in the past, but despite the progres made, the introduction of new control systems or the nonlinearities presented in the electrical machine, still makes hard the diagnosis of faults. The present study attempts to show the evolution of the induction motor signatures when electrical and mechanical faults occurs simultaneously. The analysis of the stator phase currents may lead to an accurate diagnosis of the fault due to the fact that the non-linearity interactions between the electrical and mechanical components are difficult to predict with precision. Fourier analysis has been chosen. Results shown in the present paper indicate that the consequences of the above mentioned faults in the typical analysis carried out to diagnoses the state of the electrical machine, may be interpreted as indicator of a different type of fault.
