Design of high speed induction motor 350kW, 40000r.p.m.
Karásek, Ladislav ; Vítek, Ondřej (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with the problem of the high-speed electrical machines. In the introduction summary of the high-speed machines are discussed. Induction machine with squirrel cage winding and solid rotor is chosen as suitable solution for given requirements. The multiple types of designs of the induction machines with solid rotor and problematic areas are discussed. Main part of this thesis is an electromagnetic design of the machine with respect to mechanical stress. The designed machine is analyzed with the use of finite element method in ANSYS Mechanical and Maxwell software.

The arc extinction in electrical apparatuses
Karásek, Ladislav ; Valenta, Jiří (referee) ; Bušov, Bohuslav (advisor)
My bachelor’s thesis is focused on theoretical analysis of the issues of switching arc in electrical devices, introducing successful quenching principles in present devices and the practical part of thesis is focused on innovation of lab exercises „Static V-A characteristics of DC (direct-current) arc and dynamical V-A characteristic of AC (alternating current) arc“, which is part of the course Electrical Devices. Part of the bachelor´s thesis is practical measuring of DC and AC arc, construction of static and dynamic characteristics and its subsequent reviews. The last part of my bachelor´s thesis is focused on innovation of this lab exercis
