THE DIAGNOSTICS OF INDUCTION MOTORS ROTOR BAR BREAKS BASED ON THE ANALYSIS OF ELECTROMOTIVE FORCE IN THE STATOR WINDINGS
Journal Title: Електротехніка і Електромеханіка - Year 2014, Vol 0, Issue 6
Abstract
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.
