Position control of cross-table dedicated manufacturing machine
Plocek, Jaroslav ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis treats the drive solution of the two axis cross-table of a single-purpose manufacturing machine. The first chapter analyzes the concept of drives and compares different variants using either a direct linear drive or a ball screw with a rotary servo drive. The thesis further deals with sizing the motor and the power unit assembly and the description of the whole measuring system. The structure of cascading position controller, its description and the calculation of current and speed control loops is covered in the next part. The last section discusses practical settings of all control parameters.

Simulation models of electric drive vehicles
Bílý, Lukáš ; Huzlík, Rostislav (referee) ; Havlíková, Marie (advisor)
The work deals with creating a DC electric motor drive. The model is composed of electrical power from the engine model and transistor pulse converter load, which are joined together and completed the anchor and regulate the flow control engine speed. Great attention was paid to the determination of losses in the load drive electric vehicles and create a model of electric power load. The real work was verified by an experimental model of an electric vehicle Car4 the available parameters.

Design of an Electric Motorcycle
Vítek, Jan ; Surman, Martin (referee) ; Křenek, Ladislav (advisor)
The pressure to reduce emissions and the related massive support for electromobility is growing in the world. In addition to environmental friendliness, electric vehicles have several other benefits, such as low operating costs, easier maintenance, lower noise etc. However, they are still bothered by problems with range and an insufficient network of charging stations. In an urban environment, this problem largely disappears, and on the contrary, the ecological aspect is the most pressing here. In addition, due to the density of urban traffic, the demand for single-track vehicles is growing. The solution is an electric motorcycle for the urban environment, which effectively solves these problems. Therefore, the work deals with the design of an electric motorcycle for the urban environment in cooperation with the company MSR Engines, on a technical basis provided by this company.

Electric drives in commercial vehicles and buses
Bahenský, Štěpán ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor thesis focuses on electric and hybrid powertrains, which are used in utility vehicles and buses. According to this bachelor thesis is divided into two main parts. The first part deals with pure electric drives and its basic components. The subchapters describe various types of engines that are commonly used, but also the features and technologies of batteries. The second part deals with hybrid technologies, division according to the arrangement of components in vehicles, advantages and disadvantages of these solutions. Attention is also paid to the possibilities of battery systems. At the end of both parts, there are examples of commercial vehicles and buses with appropriate motorization, their comparison with competing models and a list of chosen technical parameters. The final chapter summarizes the current direction of the market and its further possible development in the future.

The design of a two-axis manipulator
Soják, Vojtěch ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
This master thesis deals with the design of a two-axis manipulator according to entered parameters. In the first chapter provides description of kinematics structures of industrial robots and manipulators and their workspaces. Next parts focus on search in the used components, producers of manipulators and of current design manipulators at JCEE s.r.o. Lanškroun. The practical part deals with the design and construction of custom manipulator and its price calculation.
