Improvement Power Parameter of Small Induction Motors
Halfar, Tomáš ; Ondrůšek, Čestmír (referee) ; Hájek, Vítězslav (advisor)
The master’s thesis Improvement power parameter of small induction motors deals with issues of lowering the losses of small induction motors. The first part introduces with design and principles of operation of induction motors. Also introduces to theoretical problematic of losses, their lowering and measuring. In the practical part there are results of the measuring the losses in the induction motor ATAS Elektromotory Náchod a.s. T22VT512 (71-0512). There are proposed methods of increasing the efficiency of induction motor due to measuring and their verification in the Maxwell software. The last part is dedicated to measuring the losses of prototype motor from ATAS and comparison of results with previous motor.

Improving energy parameters of single-phase induction motors
Dospěl, Leoš ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
Bachelor thesis Improving energy parameters of single-phase induction motors deals with issues of lowering the losses of a small single-phase induction motor J22VV506 from ATAS Elektromotory Náchod a.s.. The first part deals with the theory of asynchronous motors and the issue of losses and their reduction is described in this part as well. In the second part engine parameters are measured and calculated efficiency of the machine and suggested ways to reduce losses. In the last part is measuring motor with the proposed regulation.

Automatic measurement of induction machine using LabVIEW
Halfar, Lukáš ; Huzlík, Rostislav (referee) ; Bulín, Tomáš (advisor)
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.

Losses analysis of small induction motors
Šišák, David ; Cipín, Radoslav (referee) ; Mach, Martin (advisor)
This bachelor thesis deals with analysis of losses of small induction motors. The first part of the project introduces the principle of operation and construction of induction motors. Furthermore, there is dealt with issuing each losses, their origin and disposition in induction motor. The project continues performing the analytical computation of the losses of induction motor with an output of 600 W. The losses of the motor are also calculated in the program Maxvell RMxprt. In the practical part, there are the results of the laboratory measurement on that motor and measurements concerning two another small induction motors different in nominal power. In the last part, there are compared the results of individual motor losses, obtained by computations and measuring. There are also compared the measuring results of losses of chosen motors depending on the nominal output.
