Design and analsysis of magnetic bearing
Kyanka, Radim ; Ctibor, Jiří (referee) ; Rúra, Dávid (advisor)
The master thesis is focused on literature research and description of magnetic bearings in order to create a design model of a stand for demonstration of magnetic levitation. The simulated model is developed using the finite element method. It also discusses the advantages and disadvantages along with a comparison with conventional bearings in drives. Analytical design is discussed here, which is also simplified and neglects several parasitic effects. These analyses are then discussed. The main part of thesis containe design and calculation for an 8-pole active radial heteropolar magnetic bearing. The result of the design is then applied to the realization of the demonstrator.

Back-to-back inverter for motors and generators
Wich, Petr ; Ctibor, Jiří (referee) ; Knobloch, Jan (advisor)
The aim of this thesis was to design and implement a back-to-back converter. It is an indirect frequency converter with a DC intermediate circuit and an active rectifier. First of all design procedure of the individual components is described with the calculation of their operating parameters. Next, the interconnection of the components and the assembly of the inverter including a virtual model is described. Subsequently, a mathematical model of the inverter was created and the control algorithm was tested on it. In the next part, the correctness of analogue value sensing by the control electronics was verified. Finally, test measurements were carried out to verify the operating parameters of the inverter, including verification of the power sizing.

Radio Controled Tracked Vehicle Model
Ctibor, Jiří ; Knobloch, Jan (referee) ; Klíma, Bohumil (advisor)
The aim of the bachelor thesis is the design and creation of manufacturing documentation DC drive for the tracked vehicle model with remote control, its design, programing and inspirit. To create a manufacturing documentation it’s needed to be familiar with the design program for printed circuit boards Altium Designer. Program of the microprocessor will be created in CodeWarrior development environment in the C language. To design circuits were used generally datasheets of components. The proposal consists of several functional peripheral units that provide various functions needed. For control the circuit is used a digital signal processor aimed at applications in the motor drives.

Data logger
Dráb, Dominik ; Pazdera, Ivo (referee) ; Ctibor, Jiří (advisor)
This master's thesis deals with design of universal data logging device. The work proposes the design of device architecture and describes individual systems and components, that are necessary for data logging. Logger is designed as a mobile device, with ARM microcontroller at its core. Thesis specifies requirements for device in terms of performance and versatility. The device uses modular construction, as it comprises multiple PCBs. The thesis describes their design and also design of the mechanical construction of data logger. Designed device has been realized and assembled. Software design for microcontroller is also part of the thesis. In the last part, measurements to determine achieved parameters of the device are conducted.

Modification of a diesel generator for parallel operation with the grid
Černý, Martin ; Ctibor, Jiří (referee) ; Knobloch, Jan (advisor)
This works applies the idea of adjustment an engine-generator, so it is possible to connect an engine-generator, or other type of a generator, to the electricity. Consequently, the machine can transform the power supply without an outage. This work concerns the complex approach, provides the descriptions of particular parts, sensors and active components of a motor-generator and includes the explanation of their function. Further research is focused on designing and drawing a plan with a choice of a control unit for the whole system. Finally, the work deals with the complex implementation and testing the machine in real operation.
