Thermal analysis of servomotor
Přibyl, Daniel ; Duroň, Jiří (referee) ; Klíma, Petr (advisor)
This thesis deals with the design of the thermal model of servomotor in program Motor-CAD and using it for analyze of servomotor. In the beginning is a short familiarization about its parts, especially important for the thermal model. Further are described principles of heat exchange. There is a chapter, which is dedicated to the program support of the Motor-CAD. Thermal model and electromagnetic model inputs are tuned according to the measured data. Then a way of active cooling is designed and based of it the model in program is edited. Using the model is found the points of load of the motor for maximum allowable temperature with water cooling. In the conclusion is a valorization of benefit of water cooling for the servomotor.

The methodology for calculation small induction motor
Bureš, Petr ; Duroň, Jiří (referee) ; Hájek, Vítězslav (advisor)
This thesis addresses analysis of problematics concerning induction motors. The introduction is dedicated to description of basic principles of induction motor functions, describes individual construction components and also focuses on brief description of current regular design of those machines. The following section is dedicated to the design method and procedure for calculating, mainly focused on single phase induction motor with connected capacitor. The last section is focused on problematics concerning induction motor efficiency together with possible methods of loss reduction and efficiency improvement following the example of engine design.

Motor-Generator For Swirl Turbine
Huzlík, Rostislav ; Skala, Bohumil (referee) ; Duroň, Jiří (referee) ; Ondrůšek, Čestmír (advisor)
The aim of this doctoral thesis is to design a motor-generator for swirl turbine. Swirl turbine is a relatively new type of turbine developed at the Department of Fluid Engineering Viktor Kaplan Energy Institute FME BUT. Swirl turbine is designed for use on small head, where the classical types of turbines either poor efficacy or are economically disadvantaged. As suitable construction for the motor-generator was selected synchronous machine with permanent magnets and with axial magnetic flow with coreless stator. As part of the work is carried out calculating the properties of turbines for defined operating point simulation model of the turbine. After already made draft motor-generator to optimally meet the characteristics of the turbine. The complete design of the motor-generator is validated by calculating the finite element method models. Designed machine must be able to work as a generator and as a motor, if it was necessary to use a turbine as a pump.

Safe brakes for servomotors
Štencl, Michal ; Duroň, Jiří (referee) ; Ondrůšek, Čestmír (advisor)
This Master thesis is focused on electromagnetic brakes for servomotors. In the first chapter is described principle of operation, later then design and main parameters are explained. The main part of thesis is focused on calculation of dynamic parameters of electromagnetic brakes. Calculations are solved first by analytic method in Matlab–Simulink, then by finite element analysis. Results are compared with measurements on prototype brake.
