Electrodynamic magnetic bearing design
Pavluš, Ondřej ; Janda, Marcel (referee) ; Rúra, Dávid (advisor)
High speed applications demands with a need for lower energy consumption lead to designing new types of bearings. In the last decades magnetic bearing, which would be able to obtain passive stable levitation using regular materials at room temperature, has been searched. This has lead to development of electrodynamic bearing based on eddy currents principle. Currently the electrodynamic bearings are still not fully explored and further research is needed. The aim of the work is to describe the theory about modern magnetic bearing, analysis and design of electrodynamic bearing according to given parameters. The finite element method is used for further analysis and evaluate behaviour of its properties.

Possibilities of elimination of electrostatic charge generation in the belt conveyor drive
Pavluš, Ondřej ; Mach, Martin (referee) ; Veselka, František (advisor)
The purpose of revision of electrical devices is to assess the device in regard to its safety. The main goal of this bachelor thesis is a revision of an electrical conveyor belt engine. We focus on safety from injury caused by electric current due to malfunction and methods for detection and prevention of electrostatic charge buildup. We conducted an inspection and prepared the required norms and measurements. After a careful analysis of results we determined, whether or not the device meets the safety requirements specified by the relevant industry norms. Based on the insights from the inspection, we took necessary precautions with regard to static electricity buildup.
