Bearings for machine spindles
Knápek, Jiří ; Nohál, Libor (referee) ; Galas, Radovan (advisor)
This bachelor’s thesis contains the survey of bearings for machine spindles. Thesis is especially focused on slide, air, magnetic and rolling bearings. Bearings are described with emphasis on their construction, lubrication and arrangements. In the end of this thesis there is a comparison of mentioned kinds of bearings for machine spindles.
Power circuits for feeding the magnetic bearing
Chudá, Kateřina ; Ctibor, Jiří (referee) ; Procházka, Petr (advisor)
Magnetic bearings are used to keep objects in certain position via magnetic force. There is no creation of friction, because there is no touch. It is necessary to supply magnetic bearings with electric energy. Linear transistor amplifiers or switched-mode amplifiers can be used to supply them with electric energy.
Mechanical Design of Flywheel Energy Storage System
Hanáček, Jiří ; Šebesta, Karel (referee) ; Hartl, Martin (advisor)
This bachelor thesis focus on flywheel energy storage construction. The aim of the work is to discuss nowadays construction types of each component of these batteries. Single chapters are focused on rotor, bearings, motor generator and enclosure of the system. There is shown a basic principle of each component and itsfunction within the battery system, used materials and shapes and other factors influencing the construction. This thesis is also focused on stress analysis of metal and composite rotor, rotor fit with help of magnetic bearings, power transfer with help of motor generator and on the enclosure design of that mechanical battery.
