Contents: The work suggested in this research consists of the detection of a three-phase short circuit in a synchronous permanent magnets machine supplied with a three levels inverter of voltage PWM, by the means of the spectral analysis of the stator currents. The practice showed that at the time of a short circuit it is primarily the stator resistance which considerably will increase. For that we establish the model of the operational engine first of all. Then we will give the model of the engine weakening and will treat the results of simulation for finally comparing the spectra of harmonics of the currents of the two models. The early knowledge of such a defect starting from a simple spectrogram makes it possible to avoid the total dysfunction of the machine.
