The influence of eccentricity upon the radial forces in an induction motor
Formánek, Jakub ; Hájek, Vítězslav (referee) ; Janda, Marcel (advisor)
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.

The centrifugal pump radial force reduction
Koutný, Luděk ; Haluza, Miloslav (referee) ; Pochylý, František (advisor)
This diploma thesis deals with problematics of the radial force effect on the runner and possibilities of the force reduction. Some pump modifications were proposed and changes of radial force magnitude in reverse blocking state and optimal flow state were examined in consequence. Following investigation was focused on the new modifications regarding to the pump efficiency and its characteristics stability. All results were carried out using the Solidworks, the Fluent and the Microsoft Excel software.
