| Özet |
| Permanent Magnet Synchronous Motors (PMSMs) are widely used in industrial automation systems due to their superiorities such as high efficiency and power factor, high power-weight ratio and high moment-inertia ratio. A new method to determine demagnetization faults in PMSMs has been presented in this study. The motor phase current has been monitored under differing speed and load conditions such as with stationary and non-stationary rotor speed and the demagnetization fault in PMSMs has been detected using Angular Domain Order Tracking (AD-OT) method. The obtained results have been compared with traditional Fast Fourier Transform (FFT) results. In conclusion, it has been observed that the proposed method has been successful in the detection of faults in stationary and non-stationary signals. Even though the proposed method has been used for a long time with vibration signals, it has been applied to PMSM current for the first time and very successful results have been obtained in the detection of demagnetization fault. |
