Project for an automouse source of electrical energy
Vinkler, Stanislav ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
Purpose of the thesis is enlarged the theory about potential utilization of an autonomous (autonomic) electric power supply used for a family house. Forepart will dealt with description of the resources in accordance with conversion of different kinds of energy to electric power. There will be always given the principle of the power generation as well as a list of main components of the system for each single source. Second part will be focused on generator output assessment of the autonomous source to ensure the power supply for the model family house. There will be my own design of the autonomous sources namely a project of a small hydropower plants and a project of a cogeneration unit in the third section of the thesis. The last part is aimed at the techno-economical evaluation of the engineered sources.

The improvement of efficiency of three-phase induction motors
Vinkler, Stanislav ; Ondrůšek, Čestmír (referee) ; Vítek, Ondřej (advisor)
This work is dedicated to increasing the effectiveness of a particular draft induction motor, which was before the change and subjected to laboratory measurements according to EN60034 - 2-1, an analytical calculation of the losses and the overall efficiency and analysis program RMxprt. The first part focuses on the analysis of measurement data, measurement of partial loss in the machine and overall efficiency. In the second chapter, losses and efficiency calculated analytically, in the first case using the links in the professional literature dealing with the design of electric motors and in the second case by a program for the rapid design of rotating electrical machines, RMxprt program. At the end of this chapter all parameters are obtained measurements and calculations are compared. The third chapter is devoted to the calculation of losses and the resulting efficiency machines in a computer program, in which I gradually adopted changes to increase the efficiency of electrical machines. It also shows the calculation of the new dimensions of the stator and rotor slots. In the fourth chapter, the preparation of documentation for the production of a new two-layer winding for the current machine, while preserving the original dimensions of stator slots. The last part is devoted to the analysis of measurement data on the supplied asynchronous motor with a newly designed stator winding. In conclusion then discussed the results of work.
