    Diagnostics of Synchronous Motor Based on Analysis of Acoustic Signals with the use of Line Spectral Frequencies and K-nearest Neighbor Classifier

    Diagnostics of Synchronous Motor Based on Analysis of Acoustic Signals with the use of Line Spectral Frequencies and K-nearest Neighbor Classifier door Adam GLOWACZ

    Gepubliceerd in 2014-06-01

    In industrial processes electrical motors are serviced after a specific number of hours, even if there is a need for service. This led to the development of early fault diagnostic methods. Paper presents early fault diagnostic method of synchronous motor. This method uses acoustic signals generated...

    DC Motor Fault Analysis with the Use of Acoustic Signals, Coiflet Wavelet Transform, and K-Nearest Neighbor Classifier

    DC Motor Fault Analysis with the Use of Acoustic Signals, Coiflet Wavelet Transform, and K-Nearest Neighbor Classifier door Adam GLOWACZ

    Gepubliceerd in 2015-06-01

    This paper focuses on testing the monitoring system of the Direct Current motor. This system gives the possibility of diagnosing various types of failures by means of analysis of acoustic signals. The applied method is based on a study of acoustic signals generated by the DC motor. A study plan of t...

    Recognition of Acoustic Signals of Loaded Synchronous Motor Using FFT, MSAF-5 and LSVM

    Recognition of Acoustic Signals of Loaded Synchronous Motor Using FFT, MSAF-5 and LSVM door Adam GLOWACZ

    Gepubliceerd in 2015-04-01

    An article discusses a system of recognition of acoustic signal of loaded synchronous motor. This software can recognize various types of incipient failures by means of analysis of acoustic signals. A proposed approach uses acoustic signals generated by loaded synchronous motor. A plan of study of a...

    Diagnostics of Rotor Damages of Three-Phase Induction Motors Using Acoustic Signals and SMOFS-20-EXPANDED

    Diagnostics of Rotor Damages of Three-Phase Induction Motors Using Acoustic Signals and SMOFS-20-EXPANDED door Adam GLOWACZ

    Gepubliceerd in 2016-04-01

    A fault diagnostics system of three-phase induction motors was implemented. The implemented system was based on acoustic signals of three-phase induction motors. A feature extraction step was performed using SMOFS-20-EXPANDED (shortened method of frequencies selection-20-Expanded). A classification...

    Theory of Synthesis of Asymmetrical Delay Line with the Surface Acoustic Wave

    Theory of Synthesis of Asymmetrical Delay Line with the Surface Acoustic Wave door Milan ŠIMKO, Miroslav GUTTEN, Milan CHUPÁČ, Matej KUČERA, Adam GLOWACZ, Eliasz KANTOCH, Hui LIU, Frantisek BRUMERCIK

    Gepubliceerd in 2019-01-01

    The aim of this publication is to design a procedure for the synthesis of an IDT (interdigital transducer) with diluted electrodes. The paper deals with the surface acoustic waves (SAW) and the theory of synthesis of the asymmetrical delay line with the interdigital transducer with diluted electrode...
