Efficiency Improvement of Small Induction Motors
Vilím, Martin ; Veselka, František (referee) ; Hájek, Vítězslav (advisor)
In this bachelor´s thesis I discuss about asynchronous engines in general, describe their construction and principle of operation, using. It also includes measurements of a specific motor and design engine. The first part deals with theprinciple of the engine options including the fundamental control over speed and torque. The second part deals with the measurement of the size of the searchengine and losses. The last part provides a proposal for a new induction motor.

Options for increasing the efficiency of small motors.
Kusý, Karel ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
This bachelor thesis concerns itself with the possibilities of achieving higher efficiency of small asynchronous motors and their manufacturing costs. The following chapters describe the design, function and principles of speed regulation of the asynchronous motor. Next, losses that occur during motor operation and ways of reducing them, are described. The last chapter of the thesis addreses factors that influence the manufacturing costs of the asynchornous motor and evaluates the material costs of one modified motor.

Classification of asynchronous motors
Čala, Václav ; Dušek, Jiří (referee) ; Singule, Vladislav (advisor)
This diploma thesis deals with a creation of a “Classification Document” of asynchronous motors with a short-circuit armature with axial heights of 355, 400, 450, 500, and 560 mm. Furthermore, it is concerned with a creation of an integral design documentation for the production and assembly of these motors at the company TES VSETÍN, s.r.o. By writing this diploma thesis I would like to achieve a simplification of communication with the customers during the processing of asynchronous motors orders and to speed up the processing of asynchronous motors orders not only in the design department but also the complete technologic preparation of the production which will surely be provided by this integrated documentation.

Brakes and retarders of commercial vehicles
Kalnický, Jakub ; Zháňal, Lubor (referee) ; Fojtášek, Jan (advisor)
This bachelor's thesis is specialized search dealing with brakes of commercial vehicles. The work is divided into six main parts. The first part deals with genesis of brakes. The second part informs about fundamental terminology and definition of braking. The third part deals with distribution of braking systems by their purpose. Contents of fourth and fifth parts are friction brakes and retarders. The last part is dedicated to development trends of brakes.

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.
