Design of permanent magnet synchronous motor
Pavláček, Jan ; Vítek, Ondřej (referee) ; Huzlík, Rostislav (advisor)
This thesis is bent proposal synchronic motor with permanent magnets. Here are described characteristic synchronic motors, permanent magnets and possibilites construction. This thesis is sorted from common description, feature and principle function. Here are also mentioned benefits and disadvantages synchronic motors with permanent magnets. Main volume of work is proposal synchronic motor with various modifications. Proposal is realized in program Ansys Maxwell (modulus RMxpert). Engine data are entered from program Excel, where is state full calculation input and output parameters. Value is tested from [11]. Aim those work are various modification synchronic motor and his analysis.

Single-Phase Induction Motor
Vácha, Pavel ; Lapčík, Josef (referee) ; Hájek, Vítězslav (advisor)
The bachelor work is concerned the thesis of a single-phase induction motor that´s perpetually more used in all over the world. Its aim is assembling the information about this type of motor and its calculation. The content of the first part is the theoretical analysis of a single-phase induction motor and acquirement ways of the stroke moment. The practical part contains a basic schema calculation of the single-phase induction motor with an auxiliary phase and a processing demonstrate example of calculation of the single-phase induction motor with concrete parameters along suggested process. In the conclusion there is the evaluation of the whole process.

Solution technology of part "solid belt pulley of hoist-elevator".
Procházka, Zdeněk ; Polzer, Aleš (referee) ; Kalivoda, Milan (advisor)
This diploma work deals with a production technology of a tractive bearer rope wheel as a part of a hoist-elevator. A design and technological analysis of the components is studied, including a functional analysis of the grooves, a selection of the material of semi-manufactured blank, a selection of the cutting materials and production machines also. New CNC programs for production of the part have been worked-out. The work includes some suggestions for testing of the part function.

Single-Phase Induction Motor Calculation
Vácha, Pavel ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
The master´s thesis deal with the thesis of a single-phase induction motor that is more and more used all over the world. Its aim is assembling the information about this type of motor and its calculation. The content of the first part is the theoretical analysis of a single-phase induction motor and acquirement ways of the stroke moment. Than the work contains a project of basic schema of the single-phase induction motor with an auxiliary phase. The practical part is devoted to an elaboration of demonstration example of the single-phase induction motor with concrete parameters calculation, its method was projected before. Than there is practising successived measuring on the motor of the same parameters made firm EMP s.r.o. Slavkov by Brno in this part. In the conclusion there is the evaluation of the whole process with reached results.

Rotor Slot Shape Optimization of an Induction Machine
Szekeres, Vojtech ; Ondrůšek, Čestmír (referee) ; Bárta, Jan (advisor)
This thesis is dealing with optimization by using artificial intelligence of an induction machine rotor slot. The one optimized is commonly manufactured induction motor with simple deep bar rotor. Goal is to design an optimization method and achieve the highest possible value of efficiency and power factor of chosen machine. Work contains the parametric model construction in Ansys Maxwell software, the optimization algorithm assembly and its setup for desirable output, and processing of the results.

Single-Phase Induction Motor Calculation
Ševčík, Pavel ; Vítek, Ondřej (referee) ; Hájek, Vítězslav (advisor)
This master's thesis considers by single-phase asynchronous motor. The first part discuss about construction, principle of operation and basic parameters of this motor type. It also discussed the emergence of torque and torque characteristics of the different types of engines. The second part explains the basic ways of obtaining grip moment including outline the principles of functions particulars constructions types, which is produce in practice. In the third part is minutely analyse single-phase asynchronous motor with auxiliary phase and permanently conect capacitor, including method of assign size of a capacitor. Fourth part section provides the principles of the procedure for calculating basic parameters of the single asynchronous motor with auxiliary phase. At the last part is accomplished a calculation of single-phase asynchronous motor with permanently conect capacitor at auxiliary phase including comparation with already manufacturing motor.

On the production of special grooves in pipes
Smítal, Tomáš ; Humár, Anton (referee) ; Píška, Miroslav (advisor)
This work was created in cooperation with company Mubea. Introduction part describes purpose of automotive headrest and function of special grooves, which are fitted on headrest frame. Overview of manufacturing technologies of these grooves with short summary of their advantages and disadvantages follows. The main part of this work consists of development of new alternative technology for manufacture special grooves in thin-walled tubes with following experimental verification of technological conditions and shape of grooves. This work also contains evaluation of tool life and wear. Interpretation of the results is performed by calculations and graphically.
