Thermal analysis of servomotor
Přibyl, Daniel ; Duroň, Jiří (referee) ; Klíma, Petr (advisor)
This thesis deals with the design of the thermal model of servomotor in program Motor-CAD and using it for analyze of servomotor. In the beginning is a short familiarization about its parts, especially important for the thermal model. Further are described principles of heat exchange. There is a chapter, which is dedicated to the program support of the Motor-CAD. Thermal model and electromagnetic model inputs are tuned according to the measured data. Then a way of active cooling is designed and based of it the model in program is edited. Using the model is found the points of load of the motor for maximum allowable temperature with water cooling. In the conclusion is a valorization of benefit of water cooling for the servomotor.

Design of high speed permanent magnet synchronous machine
Přibyl, Daniel ; Knebl, Ladislav (referee) ; Ondrůšek, Čestmír (advisor)
Bachelor's thesis is focused on problematic of synchronous machines with permanent magnets. In this thesis is described the principle of function and design solution of the machine. Furthermore it deals with stator winding, possibility of placing magnets on the rotor and used types of permanent magnets. In the part of solution of the assignment of work is made design of synchronous machine with permanent magnets with output 1,5 MW and rated speed 15000 rpm. The machine is designed with inner rotor and magnets placed on surface. The solution includes design of dimensions of stator including design of slot, design of winding and design of permanent magnet. The whole analytical design was finally compared with the results of the analysis in the RMxprt program. For machine was calculated 2D magnetic field by finite element method in Ansys Maxwell. Finally was calculated critical speed.

Representatives and the represented: trust vs. alienation
Přibyl, Daniel ; Kysela, Jan (advisor) ; Urban, Michal (referee)
These days are western democracies in serious crisis. We could observe this crisis in disconnection societal topics, not only, but especially political, from the citizens, who are affected with these topics the most. The citizens are becoming apathetic; they have no interest file their energy beyond their own private and professional life. This situation could develop in two directions. The first way means conservation of current state, status quo, and it leads to not so happy future. Or another way change of course happens and the interest in public life will be activating in the citizens. And I believe in the second possibility. However, there is lot to do, to revise many aspects of public life, e.g. political parties, funding to these parties, institute of representation and how community perceive it, or elections, the way legitimation.

Dramaturgy as an approach to the world.
Přibyl, Daniel ; KLÍMA, Miloslav (advisor) ; TOMÁNEK, Karel, Frant. (referee)
The present work aims at analysing selected social and cultural phenomena and tracing their impact on dramaturgy. For the present purposes dramaturgy is understood in two ways: firstly, as a practical theatre activity; secondly - and most importantly, in a wider sense as a discipline of artistic research that provides the chaos of the global world with important categorization and interpretation functions.
