“…Most of the diagnostic techniques used up to now are based on the analysis of the stator current [21]- [23], torque [24]- [25], magnetic flux [26]- [27] and power [28]- [31]. Moreover, different signal processing methods can be found including FFTs [32], time frequency tools [21], [33]- [34], MUSIC [35] etc.…”
