Simulation of small single-phase transformer
Nevřivý, Tomáš ; Hájek, Vítězslav (referee) ; Vítek, Ondřej (advisor)
This bachelor‘s thesis deals with the complex design of single-phase transformer for low power transfer. The basis of the work is procedure of design referred to standardized tables together with the analytical calculation of all transformer parameters. The calculated parameters are verified using by finite element method in the environment of the program FEMM. Analytical calculation is verified by simulation in stationary and quasistationary magnetic field. The conclusion of the work is supplemented by measurement of the transformer, which according to the calculated parameters was made by company of ELEKTROKOV, Inc.

Losses analysis of small induction motors
Šišák, David ; Cipín, Radoslav (referee) ; Mach, Martin (advisor)
This bachelor thesis deals with analysis of losses of small induction motors. The first part of the project introduces the principle of operation and construction of induction motors. Furthermore, there is dealt with issuing each losses, their origin and disposition in induction motor. The project continues performing the analytical computation of the losses of induction motor with an output of 600 W. The losses of the motor are also calculated in the program Maxvell RMxprt. In the practical part, there are the results of the laboratory measurement on that motor and measurements concerning two another small induction motors different in nominal power. In the last part, there are compared the results of individual motor losses, obtained by computations and measuring. There are also compared the measuring results of losses of chosen motors depending on the nominal output.
