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 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...
