Detekce mezizávitového zkratu na asynchronním motoru

Abstract

This bachelor’s thesis investigates the possibilities of detecting an interwinding short circuit on an asynchronous motor, which is crucial for ensuring the safety and reliability of electromechanical systems. The first part of the thesis is devoted to the theoretical basis of asynchronous machines. This is followed by an introduction to the diagnostics of asynchronous motors, the characteristics of the interwinding short circuit and a description of three different methods to detect this fault condition, including an evaluation of the experimental verification of the selected methods on a real asynchronous motor. Finally, the experimental results are analyzed and discussed to provide a comprehensive view of the effectiveness and reliability of each method.
