This thesis will focus on creating electromagnetic vibration generator for a project ESPOSA. This generator will be used in aeronautical application. There it will be powering required electronics. Electronics is thought a part, which will be sensing, writing and sending required data.

No-radiation effects of nuclear attacks create a big group of possible impacts on society. The first task of diploma thesis is to compile basic complex of known principles, features and descriptions of behaviour of electro technical materials, mainly in the sphere of electromagnetic fields and their interaction with surroundings on various (attack induced) outer conditions. These features are verified and demonstrated through laboratory measurements taken on basic components of the latest ICT devices. The second task is to compile the whole complex of findings and observations about SW models creations on interpersonal parallel communication. Acquired results are verified on the small group of 27 people.

The diploma thesis deals with an engineering design, a realization and a calibration of a apparatus for surface texturing of test samples. Microdents are produced by a diamond tool pressing. Electromagnetic linear actuator is used for pressing. Translation and rotation of the sample are secured by a couple of stepping motors. Thanks to this the apparatus can produce texture with well defined and easily controlled geometry. The diploma thesis contains a summary of surface texturing methods, designs of constructional variations, a electronic device of the apparatus and the calibration are also included.

This thesis deals with the design of electrical machine for direct drive of cascade liquid pumping system. At the beginning a suitable type of electrical machine and some of its basic parameters are selected. Finally, the 4 pole three phase induction machine powered by alternating voltage 3x400 V was chosen. After that complete design is made with respect to all specified requirements. The designed machine is analyzed with the use of ANSYS Maxwell and RMxprt software. The main outcome of the thesis are dimensional sketches of the engine that will be used as the basis for the production of the prototype.

The aim of the diploma thesis was to design an electromagnetic generator to the purpose of supplying signalling and safety devices on the rail tracks. The electromagnetic generator is a separate electrical source, which is mainly needed for safety in the case of not covered tracks by electrical installation. The thesis proposes two types of electromagnetic generator and one with non-linear stiffness, which are designed for the passage of trains with low frequency.

This thesis deals with the design of a five-phase machine. In the first part of this thesis are presented theoretical knowledge about five-phase machines. In the next part of the thesis is designed five-phase machine by analytical calculation according to selected parameters. This calculation includes the resulting load and start characteristics. The geometrical parameters of the machine are transferred to the Ansys program, where the finite element calculation is performed together with the required simulations. The results are compared and commented.

This work is aimed to creating a system for presentation of oscilations. The main part consist of electromagnetic damper, which properties are suitable for use in this system. In the first part are some conditions for design of damper body . In he second part are selected next parameters for electromagnetic damper and of the whole system by MATLAB / Simulink with iterative method. In last part is whole system analyzed and the results indicate next changes in the structure of the system.

This thesis deals with the problem of the high-speed electrical machines. In the introduction summary of the high-speed machines are discussed. Induction machine with squirrel cage winding and solid rotor is chosen as suitable solution for given requirements. The multiple types of designs of the induction machines with solid rotor and problematic areas are discussed. Main part of this thesis is an electromagnetic design of the machine with respect to mechanical stress. The designed machine is analyzed with the use of finite element method in ANSYS Mechanical and Maxwell software.

The thesis describes problematics of synchronous motor with permanent magnets. The design is provided by analytic and empiric procedures. The great accent is placed on the description of the magnetic circuit of the motor. The finite element method analysis of designed motor is performed subsequently. The main target of this thesis is to find the way, how the ferrite permanent magnet should be used in synchronous motor.

The master thesis deals with the construction and design of a high-speed synchronous machine with an outer rotor. The thesis is organised into three main chapters. The first chapter deals with machine design theory as well as mechanical limits, which are significant for high speed machines. This chapter also provides examples of applications of these electrical machines. In the second chapter, the initial design of the machine is calculated analytically. This machine design is optimised and the third chapter of this work shows the results of simulations using the finite elements method, including the evaluation of these results.
