This paper presents permanent magnet synchronous machines with short circuit of turns. Two-dimensional (2-D) finite element analysis (FEA) is used to simulation of PMSM under fault. PMSM is working at nominal condition and speed change of 5000 rpm. Relationships between stator-current-induced harmonics were investigated by means of Fourier (FFT) and discrete wavelet transforms (DWT). The simulation...
A closed form solution is presented for the transient and steady-state response of surface permanent magnet synchronous machines to single FET short circuit failure in the drive. PWM techniques such as sine and discontinuous switching schemes are compared with respect to the motor performance under such fault condition. With the help of the analytic model the sensitivity of the key control parameters...
This paper presents a review of Permanent Magnet Synchronous Motor (PMSM) fault diagnosis methods. Firstly, PMSM usual faults including electrical, mechanical, and magnetic faults are listed.

Finally, the artificial intelligence methods for PMSM fault diagnosis are reviewed, such as artificial neural network, fuzzy logic.
A novel approach for quick evaluation of the electromagnetically induced vibration in a Permanent Magnet Synchronous Machine (PMSM) is introduced. Field Reconstruction Method (FRM) and Mechanical Impulse Response (MIR) are used for this purpose. The electromagnetic forces and vibration emissions are analyzed in time and frequency domain for healthy and faulty cases. These analyses allow for detecting...
This paper presents a study of the permanent magnet synchronous motor (PMSM) running under demagnetization. The simulation has been carried out by means of two dimensional (2-D) finite element analysis (FEA), and simulations results were compared with experimental results. The demagnetization fault is analyzed by means of decomposition of stator currents obtained at different speeds for torque change.
This paper presents the study of permanent magnet synchronous machines (PMSM) running with eccentricity and bearings damage. The objective is to detect and identify the fault through the current signature analysis. The stator current has been analyzed by means of both Fourier (FFT) and Discrete Wavelet (DWT) transforms. Simulations have been carried out with a two-dimensional (2-D) finite element...
This paper presents a study of permanent magnet synchronous machines (PMSM) with bearing fault using a two-dimensional (2-D) finite element analysis (FEA). Fourier fast and wavelet transform were used to fault detection of bearing damage under stationary and non stationary working conditions. Simulation were carried out and compared with experimental results.
This paper presents a study of eccentricity fault detection in permanent magnet synchronous machines (PMSM), under dynamic conditions. The fault simulation was made by means of two-dimensional (2-D) finite element analysis (FEA). Joint time - frequency transforms, as Wigner Ville distribution (WVD) and Zao-Atlas-Marks distribution, were proposed for signal analysis. Simulations carried out were compared...

This paper presents and analyzes short circuit failures for permanent magnet synchronous motor (PMSM). The study includes speed transients in realistic experimental conditions. The stator current is analyzed by means of time-frequency spectral distribution (SP), Wigner Ville distribution (\WD) and Analytical Wavelet Transform (AWT); also, the ruts value of the local maximum for this distribution is...
