Measuring and analysis of non-harmonic signal in LabVIEW
Potyš, Jiří ; Janda, Marcel (referee) ; Huzlík, Rostislav (advisor)
This thesis will be concerned with using the program LabVIEW for measuring and analyzing of non-harmonic signals. An introducing of the bachelor thesis present a strict summary. The second chapter describe the program LabVIEW, its abilities and application for virtual instruments. The third part describe possibilities of using the frequency filters in signals area. The fourth part will be included the theoretical basics of the Fourier transform, its use and possible applications in LabVIEW program and the use of window functions. The fifth chapter outlines the measurement of effective values of different types of signals. The sixth chapter contain information about the measurement of active power. The seventh chapter describe the plan of the measurement program and the results of calculated and measured dates of this program. The final part make evaluating of the results of this bachelor thesis in comparison with a real appliance Yokogawa WT 1600 for analysis of signals.

Model the flow of coolant in electrical machine
Potyš, Jiří ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
The thesis is focused on possibilities of asynchronous motors cooling with use of simulation at ANSYS Workbench program. It is divided into two parts. The first part deals with analyses of cooling medium circulation through ventilator and cooling medium circulation on the motor surface. As a result of the analyses is air speed distribution and air pressure representation. The second part of the thesis includes simulation of motor temperature rise both with cooling and without cooling at Ansys Workbench application together with temperature measurement of real asynchronous motor in the laboratory. For cooling purposes air circulation was used. The goal of my research is comparison of the computing results with the measured results.
