Measurement of the asynchronous motor
Svetlík, Martin ; Ondrák, Tomáš (referee) ; Běloušek, Josef (advisor)
The work deals with the methods of measurement of various types and characteristics of induction engines is divided into three main chapters. The first chapter introduces us to the history superficially induction engines and the direction of work. The second chapter is devoted to different types of tests on this induction engines. The third chapter lists the results of measurements on two engines also known as type AOM090L02-016 (which is equipped with single layer winding) and type AOM090L02-017 (which is equipped with a double layer winding). In the end this work describing measurement of torque characteristics from run-up characteristic by using PC and freewheel.

Thermal model of high-speed induction motor
Světlík, Martin ; Mach, Martin (referee) ; Toman, Marek (advisor)
This thesis deals with thermal calculation of high-speed machines. Distribution of electrical rotating machine losses and calculation of mechanical losses in the air gap and on the ends of rotor is described in first part. Based on relationships taking into account rotor friction of the against the surroinding fluid are these calculations make. Literary search on theme of thermal calculation and principle of calculation thermal network method is descript here in the next part. Thermal network designed for specific machine and tabular of resulting temperatures are located in the last part.

Thermal Model of Outer Rotor Permanent Magnet Synchronous Machine
Světlík, Martin ; Bárta, Jan (referee) ; Toman, Marek (advisor)
Tato práce se zabývá analýzou ztrát vznikajících ve stroji, konstrukcí permanentních synchronních strojů s vnějším rotorem a popisem vztahů pro přenos tepla. Dále jsou v této práci popsány způsoby chlazení těchto strojů. V této práci jsou také popsány metody vyhodnocování teplot a aproximace přenosu tepla vedením a optimalizace LPTN. V neposlední řadě je pro odhad teplot použito strojové učení založené na naměřených datech.

The Weekend of Dermot & Grace: Eugene R. Watters' Long Modernist Poem
Světlík, Martin ; Markus, Radvan (advisor) ; Theinová, Daniela (referee)
The oeuvre of the Irish poet, novelist, playwright and essayist Eugene Rutherford Watters (later publishing under the name Eoghan Ó Tuairisc), who wrote both in English and Irish, has been mostly neglected by literary criticism. This thesis focuses on Watters' ambitious long modernist poem The Week-End of Dermot and Grace (1964), which has so far received only perfunctory critical treatment. Formally, The Week-End shows clear affinities with the works of high modernism (especially with the poetry of T.S. Eliot), especially in terms of poly- and multivocal qualities of Watters' overtly allusive language and the liberal employment of wide-ranging intertextual references. On the thematic level, the poem centres around Watters' preoccupation with the dropping of the first atomic bomb on Hiroshima on 6th August 1945 by the American forces, a momentous event that impelled the poet to questions about faith, civilisation, technology, and collective guilt in the context of the Irish neutral stance during the Second World War. Reflections on Hiroshima also led him to contemplate the role of the poet and poetry in the modern "atomic age". Given the aforementioned qualities of the work, the method chosen for the analysis consists of a close reading of the poem in the light of the historical, literary, and...

Losses And Heat In High-Speed Machines
Světlík, Martin
This paper deals with thermal calculations of high-speed machines. The first part of the paper is focused to determination of mechanical losses that are dominant in high-speed machines. Based on the presented procedures, a calculation of machanical losses of the specific high-speed machine was performed. The second part of the paper deals with a description of a thermal network for modeling of temperatutes in the motor .
