Paper presents method of diagnostics of imminent failure conditions of induction motor. This method is based on a study of acoustic signals generated by induction motor. Sound recognition system is based on algorithms of data processing, such as FFT and classifier based on words. Software of sound recognition of induction motor was implemented. Studies were carried out for four imminent failure conditions of induction motor. The results confirm that the system can be useful for protecting the engines and metallurgical equipment. System can be useful in inspection of metallurgical products.

Referat opisuje metodę diagnozowania stanów przedawaryjnych silnika indukcyjnego. Metoda ta oparta jest na badaniu sygnałów akustycznych generowanych przez silnik indukcyjny. System rozpoznawania dźwięku oparty jest na algorytmach przetwarzania danych takich jak algorytm FFT i klasyfikator oparty na słowach. Zaimplementowano oprogramowanie rozpoznawania dzwieku silnika indukcyjnego. Przeprowadzono badania dla czterech stanów przedawaryjnych silnika indukcyjnego. Wyniki badań potwierdzają, że system może być przydatny do ochrony silników i sprzętu hutniczego. System może być przydatny do kontroli wyrobów hutniczych.
