Suggestion of electric scooter
Lamberský, Václav ; Tůma, Zdeněk (referee) ; Synek, Miloš (advisor)
The topic of this master thesis is the design of electric scooter. In the first part of this thesis consists if research of used structural designs and driver types. In following chapters are calculations and selection procedures of the electric motor, batteries and other accessories. Results from previous chapters were used to created complete 3D model of scooter in SolidWorks software. Based on the model, complete technical drawings were created.

The redesign of the compressor for electromotor driving
Mikulka, Vít ; Venclík, Jiří (referee) ; Mazůrek, Ivan (advisor)
This bachelor thesis deals with redesign of the compressor for electromotor driving. First part focuses on the principle of compressors, their development and division. The next part describes a compressor MK 100 produced by Benda kompresory Ltd. company. The technical solution of its redesign for 2,2kW electromotor propulsion with maintaining a rotation speed mode of original Honda engine is explained in the last part. This compressor should be used in its redesign version at FME BUT in Brno.

Mobile Wood Splitter
Felcman, Miroslav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main aim of the bachelor thesis is to design a mobile horizontal woodlogs splitter according to preset parameters. The part before the main design of a splitter is focused on different types of mobile splitters with the subsequent focus on the individual structural design of horizontal splitters. The next part is dedicated to design and calculation of a hydraulic circuit of the splitter that generates the required cutting force. There is a calculation of final splitting force and other working properties for all individual components of hydraulic circuit. The individual components of the splitter are stressed by the splitting force. There is a strength check of exposed parts in the last part of the thesis. The work also includes drawings of selected parts.

Sacristian bell operation control by programmable logic controller
Křížek, Ladislav ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
The bell is described, its parts and constructive suppositions for the right function in this work, sacristian bell operation control with hand-working and with the rotating electromotor. Programmable logic controller machine SIEMENS Simatic S7-200 CPU 221 is also described, which is the part of ringing machine in Bukovinka’s church. This ringing machine and especially the mode of both bells have specific defect. According to owner´s wishes and instructions were two variants prepared for this ringing machine to improve the working of couple bells. One of these variants was tested and just tuned at the ringing machine. This one variant follows the owner´s wish, works in Bukovinka´s church till now.

Positioner for Solar Panel with Power Efficiency Optimizing
Kreysa, Karel ; Punčochář, Josef (referee) ; Šebesta, Jiří (advisor)
This thesis is focused on design and prototyping of solar panel position control system for an obtaining of the maxima renewable energy from sun. In this thesis, various ways of solar panel positioning are considered and analyzed. Consequently, a construction arrangement of the positioner is presented. It is mechanically adapted to obtain the maximum efficiency in typical environment corresponding with the Central European geographical latitude. Different methods of sun monitoring are considered and analyzed. On the basis of this analysis, a proper prototype of sun monitor for exact positioning with disturbance filtering has been constructed. Following part of work is devoted to stable, fully automated, control subsystem for reliable functionality of solar system. A suitable microprocessor with a robust firmware has been implemented to this control unit. Finally, system parameters measurement and closing analysis of gained renewable energy and backflow computation is presented in the end of this diploma thesis.

The concept of electric motors used in vehicles
Polnický, Vít ; Repka, Martin (referee) ; Böhm, Michael (advisor)
This bachelor’s thesis deals with the description of electric drives concepts in current vehicles. In the first part, the basic principle of the electric motor is explained, and different types of electric motors are described in detail. In the next part of the thesis, the electrified vehicles are divided into three groups according to the power share of electric motor for vehicle propulsion. The groups are further subdivided according to the powertrain arrangement in the vehicle, indicating the advantages and disadvantages of each concept. In the third part, specific vehicles from each group are presented and compared in terms of performance, range and price. Finally, the concepts are evaluated and a possible development is outlined.

Design of a desk coin sorting machine
Uhrová, Simona ; Čípek, Pavel (referee) ; Svoboda, Petr (advisor)
The bachelor thesis demonstrates the design concept of a low cost electromechanically driven coin sorter that can be created by the utilization of additive manufacturing, specifically 3D printing. Technical drawing documentation of the chosen design concept is then provided as well as insight into the 3D printing process. In the conclusion, the working model of the coin sorter is created, and an analysis is offered of potential problematic areas as well as possible improvements and extensions.
