TY - JOUR TI - Application of wavelet analysis for induction motor faults diagnostics operating at variable load AU - Dulęba, Dominika AU - Sułowicz, Maciej TI - Application of wavelet analysis for induction motor faults diagnostics operating at variable load AB - Technical condition assessment of induction motor can be done with stator current analysis. This analysis can be done in steady state with FFT transform. Starting current analysis with wavelet transform is a very good method of cage condition assessment. The advantage of this method is that we can observe how characteristic components vary in time. Characteristic fault symptoms can be observed when the machine is working with alternating load which causes rotor’s angular speed and slip change. Transient states when the load changes, occur very often increases the application of thism method. This paper presents the results of application wavelet transform in motor fault diagnostics in transient states.
