Design of a prototype table winder for linear coils
Ryza, Vojtěch ; Hrabčík, Miroslav (referee) ; Řehák, Kamil (advisor)
The diploma thesis deals with the design of a prototype table winder for linear coils. The first part of this work describes the basic properties of the coil and its winding methods. In the following section, a critical search was made of the reels available on the market based on which the reel concept itself was created. The work describes in detail the procedure of the winder design together with the design variants of the individual parts of the winders. At the end of the diploma thesis is presented the needed prototype of the coil winder. This problem was solved by using the 3D program SolidWorks and FEM in the program ANSYS Student. The project describes the individual steps of the design of the concept of a prototype linear winder and the component's design.

Low power current transformers
Zolich, Ladislav ; Hrabčík,, Miroslav (referee) ; Dostál, Lukáš (advisor)
Master‘s thesis is focused on current instrument transformers, current sensors and low power current transformers. Discussion is made on advantages and disadvantages of each measuring principle. Low power current transformers is then designed and manufactured. Manufactured LPCT is then measured for accuracy class. Results are then compared.

Single-Phase Induction Motor Calculation
Ševčík, Pavel ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
This master's thesis considers by single-phase asynchronous motor. The first part discuss about construction, principle of operation and basic parameters of this motor type. It also discussed the emergence of torque and torque characteristics of the different types of engines. The second part explains the basic ways of obtaining grip moment including outline the principles of functions particulars constructions types, which is produce in practice. In the third part is minutely analyse single-phase asynchronous motor with auxiliary phase and permanently conect capacitor, including method of assign size of a capacitor. Fourth part section provides the principles of the procedure for calculating basic parameters of the single asynchronous motor with auxiliary phase. At the last part is accomplished a calculation of single-phase asynchronous motor with permanently conect capacitor at auxiliary phase including comparation with already manufacturing motor.

Analysis of the stator and rotor pack termination effect on the synchronous machine by FEM
Michailidis, Petr ; Valenta, Jiří (referee) ; Skalka, Miroslav (advisor)
This thesis deals with simulation’s possibilities of the electromagnetic fields in electrical machines. A finite element method is the final element technique. The content of this thesis is a model and mesh creation and electromagnetic simulation of synchronous machine. The stator and rotor pack termination effect on the synchronous machine.is analyzed by finite element method in ANSYS program. The type of the stator termination pack is described by four segments. The magnetic field distribution is deformed due to the material properties of used segments. In the next part a methodics of mesh creation is shown. The mesh quality (in term of elements number and elements shape) is important due to the solution accuracy and speed.

Improvement Power Parameter of Small Induction Motors
Kuda, Roman ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
This master´s thesis treats of all asynchronous motor. The project is about type and distribution motors, about differences between three-phase and single-phase machines and efficiency. In one of the chapters describes a particular type of engine with all the parametersfrom the manufacturer. This engine is completely analyzed and it is measured in detail. Then the project deals with the division, the calculation of losses and subsequent possibilities to increase the efficiency of induction motor. In the last chapter is calculation of single-phase motors, based on the engine produced.

Device for stringing cable on a drum
Polách, Martin ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The thesis deals with the design of a cable spooling device on a spool drum under different modes of operation of winding. The focus is on the calculation and design part, where the calculations include the functional dimensions of the individual components and the force effects emanating from the load generated during winding. The design part includes the design of the individual components. Finally, an analysis of the selected structural nodes under different winding modes was performed. This work includes drawings containing the overall equipment assembly, subassembly of the weldment frame and shop drawings.

Solid State Tesla Coil
Pařenica, Jakub ; Mikláš, Ján (referee) ; Martiš, Jan (advisor)
The bachelor's thesis focuses on a theoretical description of the operation of Tesla's transformer, its design, including electronics, and its subsequent construction. The basic theory of the transformer replacement scheme is described. The Tesla transformer is generally described, as well as the methods of excitation of the primary side of the transformer, the generation of the discharge, the skin effect and the meaning of resonance. Furthermore, the work describes the construction of the primary coil holder, secondary coil. The work contains a pattern of the power board from the Eagle program, and everything is accompanied by photos. The work describes the recovery procedure and describes all the waveforms that were measured before and after the connection of the secondary coil.
