Možnosti využití diagnostiky poruch asynchronních motorů

Abstract

This thesis discusses fault diagnosis of cast rotor in asynchronous motors. The introductory part of the thesis describes various methods of fault diagnosis in asynchronous motors. Here, the method of frequency-analysis with the help of stator current is detailed. Thanks to this, fault detection is possible through non-destructive methods. The main part of this thesis focuses on practical measurements, where it was possible to compare results of rotors, both with and without faults, in partly rotor bars. The findings are presented in the fourth chapter of this thesis.
