Design of permanent magnet synchronous motor
Pavláček, Jan ; Vítek, Ondřej (referee) ; Huzlík, Rostislav (advisor)
This thesis is bent proposal synchronic motor with permanent magnets. Here are described characteristic synchronic motors, permanent magnets and possibilites construction. This thesis is sorted from common description, feature and principle function. Here are also mentioned benefits and disadvantages synchronic motors with permanent magnets. Main volume of work is proposal synchronic motor with various modifications. Proposal is realized in program Ansys Maxwell (modulus RMxpert). Engine data are entered from program Excel, where is state full calculation input and output parameters. Value is tested from [11]. Aim those work are various modification synchronic motor and his analysis.

Analytic represantation of AC winding properties
Kubín, Tomáš ; Skalka, Miroslav (referee) ; Ondrůšek, Čestmír (advisor)
My bachelor thesis deals with the issue of overview diagram of magnetic fields of basic free-phase winding. It is divided into four parts.The first part focuses on basic winding types and types of their connection. The second part describes the issue of analytic calculation of the magnetic field intensity in the air gap of rotating machines. This description is easier and faster than modern method of final elements in some cases because it displays course of particular harmonics and their partial sums for selected magnetic fields. The third part presents Görges diagrams of basic winding types and finally there is a calculation of the winding factor shown on two examples in the fourth part.

Draft controlled modular source 6,3kA / 5VAC for warming trials and tests breakers
Zolich, Ladislav ; Dostál, Lukáš (referee) ; Dohnal, Petr (advisor)
The main object of this thesis is to design a toroidical transfomer on the given parameters. Project is focused on learning about principles of transformers, it’s designing and mainly on designing the given transformer. Designing contains material selection of the core of the transformer, its size, then calculating magnetic flux, no-load current, cross-section of conductor and calculating no-load losses and joule losses. The next part is designing the mechanical parts of transformer, its terminal plate, base and cooling system. Thesis is also mainly focused on designing the form for potting the transformer in epoxy resins. In the end is measurement and form of powering the transformer.
