Falkowa analiza strumienia osiowego silnika indukcyjnego pracującego na biegu jałowym

The paper presents application of the wavelet analysis of axial flux in induction motor. The asymmetry in stator winding has been modeled to produce the axial flux. The axial flux has been measured using search coil mounted in end-turn stator winding area for six configuration of stator winding asymmetry. The analysis of obtained measurements has been made using FFT, discrete stationary wavelet transform (DSWT) and wavelet packet decomposition (WPD). On the basis of the results it can be concluded that the DSWT can be used in de-noising process and the WPD can used to prepare input vector for artificial neural network.
