Diagnostics of rotating electric machines
Soukup, Patrik ; Mach, Martin (referee) ; Janda, Marcel (advisor)
The thesis Diagnostics of rotating electric machines deals with the theory of diagnostics of rotating machines, focusing especially on the diagnosis of asynchronous motors of high power. Due to the importance of maintaining the trouble-free condition of these machines with regard to serviceability, the importance of their diagnosis is growing. Due to inappropriate working conditions or for many other reasons, different types of malfunctions may occur in the machine. The list and the way of occurrence of possible failures are included and explained in this thesis. With the growing age of the machine, it is important to check the insulation status through insulation testing. These tests are performed in the practical part of the thesis and the results are presented. In the case of asynchronous machines, each anomaly leaves a signature in the form of an electrical, magnetic or vibrational signal. These signals are analyzed and evaluated using a specific measuring equipment with the intention of deciding on the current state of the machine. Motor current signature analysis (MCSA) is considered to be the main diagnostic method of asynchronous machines in this thesis. This method is described in detail in this paper and is being applied in electrical engineering.

Power supply in an automobile
Soukup, Patrik ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
This work deals with the study of automotive alternators and their theoretical analysis. We can find there a listing of losses arising from the alternator, explanation of their formation and also the way of their reduction. Losses reduction is one of the aspects of innovation leading to increase in overall efficiency of the automotive alternator. Therefore a design of particular ways of innovation is made in this work and subsequently the design is verificated using Maxwell - RMxprt.
