Design, optimization and full load circuit simulation of the surface mounted permanent magnet machine
Bláha, Martin ; Ondrůšek, Čestmír (referee) ; Kurfűrst, Jiří (advisor)
This thesis deals with the possibility of using the finite elements method for the analysing of synchronous permanent magnets machines. The aim of this work is to discuss the possibility of the machine design more effectively with using the finite elements method and Maxwell software for the simulations. On the created parametric model, simulations were performed according to master thesis assignment. The aim of this work is to determine induced voltage, iron losses, machine inductances and make a permanent magnets demagnetization analysis. From simulations results the machine efficiency is calculated. The parametric model was used for the optimization of selected parameters. From results of optimization new dimensions of permanent magnets was obtained. Machine efficiency was increased by new permanent magnet material and optimized design.

The electronic commutation motor
Bláha, Martin ; Huzlík, Rostislav (referee) ; Melichar, Petr (advisor)
This work discusses about nowadays problematic of the electronic comutation motors.This work also describes the opportunity of electronic control of these motors. The result of this work is realization of electronic control circuit from discreet components. There also are mentioned is proposal of electronic control board from SMD components. This control board include temperature control with ventilator switching , commutation logic, PWM speed control. In the last part of this paper are results of evaluation measurements of EC motor.

Lifestyle of students PF JCU
BLÁHA, Martin
This work is focused on lifestyle undergraduate JCU - PF, Health education, full-time and combined studies in Czech Budejovice. From the available material, we focused on quantitative research, where the main method is querying. The work consists of theoretical and practical part. The work describes health, determinants of health, health promotion, physical activity, mental hygiene, etc. It portrays the lifestyle in general terms. It describes the components of lifestyle (sleep, food and drink, leisure, stress, alcohol, smoking, sexual behavior, drug use). Subsequently, through a questionnaire survey analyzes the attitudes and experiences of college students with their lifestyle and everything lifestyle related and belong to him. It was important from the present findings to determine whether the lifestyle of students considered healthy and what is the current lifestyle of health education students, full-time and combined studies.

Production management at the company Ekvita spol. s r.o.
Doležal, Ondřej ; Svobodová, Hana (advisor) ; Bláha, Martin (referee)
The thesis deals with operative production management at the company Ekvita s.r.o., which specializes in jobbing production in the mechanical industry. The thesis describes the company from the operational management and operative production control perspective. Emphasis is also laid on the programme equipment of the production management, namely the Herakles programme. The thesis aims to examine its capabilities and to suggest an upgraded application within the company. Particular suggestions can be found in the closing part of the thesis.
