Abstract:
This master thesis deals with calculations and simulations of multi-speed induction motors. In the first part, basic principle of these machines is described. Next, there are given three examples of pole-changing stator windings and their properties are analyzed (winding factors, magnetomotive force). Main part includes simulations and measuring of the specific motor, which is produced by company Siemens Mohelnice. This is the motor with 2/1 pole-changing in Y/YY connection. First, influence of skewed rotor slots on current and torque is analyzed. Next, parametres of motor from simulations are given and these results are compared to measured values.

Abstract:
The master thesis is focused on the calculation of electrodynamic forces acting on the contacts of the moulded case circuit breaker Siemens 3VA5 from OEZ Letohrad. This work is divided into ten chapters. In the introductory chapter it is described why it is important to deal with the calculation of the electrodynamic forces and the design of the current path. The second chapter describes the problem of the origin and effect of electrodynamic forces on individual parts of the electrical device. The third chapter describes the parameters, properties and design of the 3VA5 Siemens circuit breaker. The fourth chapter describes the Finite Element Methods. The fifth chapter describes how to create a 3D current path model in Solidworks. The sixth to ninth chapter is focused on the stationary calculation of moments in the program Ansys Maxwell by means of Magnetostatic Analysis and on the calculation of the total repulsive force between contacts with the influence of ferromagnetic materials. The last chapter is focused on dynamic calculation of moments and forces acting on contacts in a certain time interval.

Abstract:
The aim of this master thesis is to get familiar with the influence of radial forces in the induction machine. Induction motor is one of the most commonly used and most extended type of machine, therefore it is useful to detect the intensity of theese forces and their influence at operation of the machine. In this work ,radial forces are computed by the software simulation in ANSYS Maxwell. Models are created with help of module Rmxprt and finite elements method.These models are based on real induction motors with predefined size of eccentricity. In the final part we perform a measurement of deviations on the real machine using vibrometer.

Abstract:
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.

Abstract:
Master thesis deals with analysis of the definite synchronous reluctance motor with salient poles and design of synchronous reluctance motor with barriers for magnetic flux. The work is divided into five parts. In the first part there is a brief overview of realized synchronous reluctance motor designs and also operating principle of motor of this type is described. The next part contains the basic parameters of the synchronous reluctance motor with salient poles; the parameters were found with analytical calculation. The third part demonstrates verified by means of FEMM results of analytical calculations for linear and nonlinear states and with transient analysis of motor using Ansys Maxwell environment. In the following part results of testing of the synchronous reluctance motor with salient poles are presented as well as the comparation of these results with calculated values and the results of simulations. The closing part of the thesis shows the design of synchronous reluctance motor with barriers for magnetic flux. All obtained parameters were examined using FEMM and Ansys Maxwell. The final version of the proposed motor was analysed when supplied directly by mains and through the converter by Maxwell- Simplorer co-simulation.

Abstract:
This Thesis deals with problematics of residual current circuit breaker and its eventual operation malfunction due to DC components. There are magnetic phenomena described in details which occur inside of the apparatus. Consequently, there is proposed a mathematical model of the circuit breaker in Simulink program. The comparison of B-H curves of transformer core is composed and achieved results are incorporated into the proposed model in order to verify a correct operation of the circuit breaker and its reaction to different conditions. The verification of the symmetry of the magnetic field in residual current circuit breaker in Ansys Maxwell program is also a part of the study.

Abstract:
The main purpose of the thesis Automatic measurement of induction machine using LabVIEW was to develope an automated measuring system, which is used to perform tests of induction motors. The algorithm of the system is programmed in LabVIEW. In the practical part of this thesis, a measurement of the motor Atas Elektromotory Náchod a.s. T22VT512 is carried out, in order to verificate functions of the algorithm, and to perform tests of the motor to analyse losses. Another part of the work is dedicated to the electromagnetic calculation of the motor T22VT512. For this purpose, two softwares with different principles of calculation have been used. Firstly, the calculation is solved by an analytical based software called RMxprt. Secondly, the software Maxwell 2D is used to make the calculation of electric and magnetic fields by the finite element method.
