  • MCSA with Normalized Triple Covariance as a bearings diagnostic indicator in an induction motor

    Publikacja

    - Rok 2016

    Statistics of bearing failures in induction motors indicate, that they constitute more than 40% of IM damage, therefore bearing diagnosis is very important. Vibration methods for bearing diagnostics have one major disadvantage - they require the availability of the machine for sensors installation. This is the reason for seeking new methods based on motor supply current analysis. Diagnosis of induction motors, conducted remotely...

  • Induction Motor Bearings Diagnostic Using MCSA and Normalized Tripple Covariance

    Publikacja

    - Rok 2015

    Diagnosis of induction motors, conducted remotely by measuring and analyzing the supply current is attractive with the lack of access to the engine. So far there is no solution, based on analysis of current, the credibility of which allow use in industry. Statistics of IM bearing failures of induction motors indicate, that they constitute more than 40% of IM damage, therefore bearing diagnosis is so important. The article provides...

  • Induction motor bearings diagnostic indicators based on MCSA and normalized triple covariance

    Publikacja

    - Rok 2017

    Induction motors are one of the most widely used electrical machines. Statistics of bearing failures of induction motors indicate, that they constitute more than 40% of induction motor damage. Therefore, bearing diagnosis is so important for trouble-free work of induction motors. The most common methods of bearing diagnosis are based on vibration signal analysis. The main disadvantage of those methods is the need for physical access...

  • Current-based higher-order spectral covariance as a bearing diagnostic feature for induction motors

    Publikacja

    - INSIGHT - Rok 2016

    Conducting the diagnosis of induction motors remotely by analyzing the supply current is an attractive prospect with the lack of access to the engine. Currently, there is no solution, based on analysis of the current, the credibility of which would allow its use in industry. The statistics of bearing failures in induction motors indicate that they constitute more than 40% of induction motor damage, therefore, bearing diagnosis...
