Impact of winding on induction machine characteristics
Mikmek, Vladislav ; Janda, Marcel (referee) ; Mach, Martin (advisor)
This thesis deals with the analysis of a three-phase winding of an induction engine. After the theoretical introduction concerning different types of windings, two types of their analysis and the importance of the winding factor, two methods of analysis and design tools are explained: Görges diagram and Tingley scheme. This scheme is then used for the design of all possible variants of winding for a certain number of stator slots and the theoretical shape of magnetic field is analysed. The next step is a deeper software analysis of the engines with variants of windings with different coil pitches and number of conductors per slot. Especially the finite element method is used in this part. The obtained values and their characteristics of the simulated engines are compared numerically and graphically. Then the changes of important values for different windings are described. The optimal winding according to chosen requirements is chosen.

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.
