Bearing diagnosis of electrical motors
Kratochvíl, Lumír ; Janda, Marcel (referee) ; Vítek, Ondřej (advisor)
This work breaks down the individual phenomena and findings that have as a common denominator the emergence of irreversible processes leading to damage to bearings in electrical machinery and equipment. The introduction describes the basic description and division of bearings with the recommended methods of their basic operation. The following chapters then deal with the individual sources of damage, diagnostics of individual damages, or examine in more detail the accompanying phenomena of bearing damage. In the first practical part of the work, damaged bearings are physically analyzed and their diagnostics is performed on an electron microscope. The second part of the work deals with vibrodiagnostics and the use of appropriate methods to determine the condition of the rolling bearing and then the location of the source of vibration at error frequencies.
