| Résumé: | A method for diagnostics of the induction motor rotor bar breaks, based on the wavelet-analysis of the electromotive force induced in the stator windings in the rundown mode is developed. A method for decomposition of the electromotive force of the stator winding phase to the electromotive force signals of the active sides of winding coils using Z-transformation theory is developed. The effectiveness of the proposed diagnostic method was experimentally confirmed. |
