Control of Linear Motor based on Ultrasonic Detection
Veselá, Klára ; Kolářová, Jana (referee) ; Sekora, Jiří (advisor)
The focus of this bachelor thesis is to do research on possibilities of contactless distancemeasurement and linear stage construction. The first part describes four types of enginespossible to use in linear stages, their principles, advantages and disadvantages. Nextpart is focused on possibilities of contactless distance measurement. Based on thedescriptions, the most suitable modules are selected for the design of the system. Thissystem will maintain a constant distance from the object by using contactless distancesensor and linear motors.

Electromagnetic recoil system for simulated weapons
Vladík, Jakub ; Jirgl, Miroslav (referee) ; Baštán, Ondřej (advisor)
Main goal of this work is to analyze the feasibility of an electromagnetic recoil simulator on weapon replicas. The thesis explains the basic function of self-loading firearms based on the HK 416 weapon and then the concept of recoil and its meaning. Lists today's recoil compensation options. It then defines possible electromagnetic solutions as a replacement for the existing pneumatic recoil system. Some posibble solutions mentions DC motor, solenoid, linear motor and railgun as possible. The thesis lists DC motor, solenoid, linear motor and railgun as possible solutions. The best solution is a tubular linear motor combined with a power supply containing Li-pol batteries.

Design of synchronous linear motor
Jindra, Michal ; Mach, Martin (referee) ; Knebl, Ladislav (advisor)
Proposed thesis is focused on synchronous linear motor with an iron core, the design of an equivalent magnetic circuit and its calculation. The work describes the principle of a synchronous linear motor with permanent magnets, U-channel linear motor and a tubular linear motor. For these types of linear motors, the design solution is described and general advantages and disadvantages are mentioned. The losses generated in the motors are also described. The work introduces various methods of engine calculations that can be used for subsequent application to a particular type of motor. Subsequently, one of the methods is selected and used to calculate the motor. The last part is the evaluation and comparison of results.

Design of synchronous linear motor thermal network
Čech, Jan ; Toman, Marek (referee) ; Knebl, Ladislav (advisor)
The first part of this thesis deals with the study of linear motors. The introduction of the thesis deals with the brief description of the linear motor, including its accessories. This part explains principle of linear motors, their general advantages and disadvantages. The next section contains an overview and division of the currently used linear motors. The second part deals with the theoretical description of forms of heat transfer. The third part of the thesis deals with the design of an equivalent thermal circuit model of a linear iron-core linear motor with permanent magnet. Hereafter, the proposed design will be used to calculate the temperatures of the individual motor units. The temperatures are later compared with the results obtained with finite element method.

Comparison of the of precision manufacturing of holes during laser cutting of materials on various types of CNC cutting centers
Petruška, David ; Dostál, Jan (referee) ; Mrňa, Libor (advisor)
The thesis compares the precision of 90x90 mm laser cutouts with circular and quadrangular holes which are divided into two CNC cutting centers with different axle drive types. On both machines, the samples are cut through both oxidative and fusion cutting. Measurement was carried out using a sliding scale and for a more detailed and accurate analysis on a 3D coordinate measuring machine with a touch system. The results of the measurements showed that the more suitable cutting method for sheet metal cutting CSN 11321 DC01 is melting. Deviations of the nominal dimensions are comparable when cutting on both machines, so the choice of the machine for production speeds, operating and acquisition costs depends on the serial production of these burners.

Design of linear motor with permanent magnets
Čech, Jan ; Bulín, Tomáš (referee) ; Knebl, Ladislav (advisor)
The first part of this thesis deals with the study of linear motors. The introduction of the thesis deals with the brief description of the linear motor, including its accessories. This part explains principle of linear motors, their general advantages and disadvantages. The next section contains an overview and division of the currently used linear motors. Each type of currently used linear motors is briefly introduced and also its principle and characteristics are described, including its specific application. The second part of the thesis deals with the design of an equivalent magnetic circuit model of a linear iron-core linear motor. Hereafter, the proposed design will be used to simulate the distribution of magnetic flux in the linear motor. The evaluated flux-density distribution in the air gap is later compared with the results obtained with finite element method. The thrust is then calculated from the flux-density and the estimated value is compared with the value listed in datasheet.
