Návrh synchronního motoru s vnějším rotorem a s permanentními magnety / Design of outrunner PMSM

Dudáš, Juraj January 2015 (has links)
The diplomatic thesis will describe the principle functions of synchronous motors with permanent magnets, for therein analysis of PMSM and BLDC motors. We will make calculation of the required parameters from the power unit for glider Discus 2. We will create a design of BLDC and PMSM motor from specified parameters. Features of the proposed engines will be verified with the help of the programs FEMM, RMxprt, Maxwell. At the end of the work will make conclusion about the diplamatic project and diffrences between PMSM and BLDC motor.

Návrh referenčních modelů kluzáku L23 Blaník / Design of system model of L23 Blanik sailplane

Šenkýř, Miroslav January 2013 (has links)
The aim of this diploma thesis is to create useful reference models of the glider L-23 Super Blaník and their use for framework proposal technology of production, which will improve accuracy and reduce labor intensity of production. The introduction of the thesis describes history of glider and historical overview of geometry transmission in terms of structure. The next chapter of the thesis deals with the description of reference models and rules of their creation. Section describing coordinate systems is closely linked with the previous chapter. Another section of thesis is dedicated to the importance of reference models in the product lifecycle. The creation and tuning of reference models of glider is described in the next chapter of thesis. The penultimate chapter deals with experiment, which allowed verification of reference model and product. The conclusion of the thesis describes proposed technology of production where used verified reference models and modern tools of CAD systems refine and facilitate production. The main objective in designing of reference models was the definition of high quality and usable surfaces. Also proposal technology of production was processed in order to ensure the improvement and simplification of manufacturing process.

Systém pro sledování trajektorie objektů pohybujících se v prostoru / System for Trajectory Tracking of Objects Moving in Space

Jakubíček, Patrik January 2016 (has links)
This thesis deals with a system for tracking the trajectory of the moving object. Further, also for obtaining additional motion data and other information. Thesis focuses on flying objects. There are described all system components and way of their communication. Next, the progress of the expansion unit for measuring by the BeagleBone Black platform. Also there is described testing that took place during aerobatic gliders races, including the demonstrations of recording data and their processing.
