“…Therefore, the magnetic induction is beyond the saturation bend. This increase in current is caused either by an increase in the supply voltage or by an ITSC fault [23][24][25]. To detect the MSP, a problem arises because many studies have proven that the MSP indicators manifest themselves in the same signatures as those of the ITSC fault [23][24][25].…”

This paper proposes a new approach for discrimination between short circuit fault, magnetic saturation phenomenon and supply voltage unbalance in permanent magnet synchronous motor. This proposed approach is based on tracking the simultaneous position in the polar coordinates of the amplitude and phase angle of the voltage and current indicator FFT signals of the harmonics characterizing the three phenomena. The voltage indicator set using three supply voltages to check the status of the power source. In the same way, the current indicator defined using three line currents to discriminate between the short circuit fault and the magnetic saturation phenomenon. To highlight the effectiveness and the capability of this approach, a series of simulations are performed on signals obtained from a permanent magnet synchronous motor mathematical model. This model is based on a 2D-extension of the modified winding function approach.

“…In recent decades, the use of PMSM is constantly increasing in many industrial and energy fields, such as rail and aeronautic transport, electric vehicles, electric traction, electric propulsion and wind farms. These motors, associated with inverters, have a more compact structure, a high specific power, and a higher dynamic response compared to conventional structures (direct current motors, synchronous wound rotor motors or induction motors) [1][2][3][4][5][6][7][8].…”

“…For this reason, it is important, from an industrial, economic, and scientific standpoint, to diagnose the faults affecting the PMSM as of their appearance. This early detection increases the life of these motors, thus minimizing financial losses due to the unscheduled shutdown of the production chain [1][2][3]8]. Among these faults, the demagnetization of the Permanent Magnet (PM) is one of the most critical faults in PMSM, due to their relatively high cost which represents approximately 50 % of the total cost of the machine [3,9].…”

This paper proposes the development of a new mathematical model dedicated to the diagnostic of the partial Demagnetization Fault (DF) in Permanent Magnet Synchronous Motor (PMSM). To do this, an extension of the Modified Winding Function Approach (MWFA) is proposed to accurately take into account the air gap asymmetry caused by the Demagnetization Fault (DF) in the PMSM inductances calculation. The calculated inductances are then used in the magnetically coupled electrical circuit model to simulate the PMSM behavior in the different operating modes. Finally, a diagnostic method based on the stator current spectral analysis is used to highlight the PMSM stator current spectral content in the various operating modes (with and without Demagnetization Fault).
