Properties of whiper motor
Kůta, Aleš ; Skalka, Miroslav (referee) ; Janda, Marcel (advisor)
Nowadays a need of numerical computations of different tasks in the area of electrical engeneering is still rising. Common denominator of great demands given on a constructor and ecomonization of manifacturing is a requirement of efficiency. It´s necessary to use a characterictics of construction, own fundamentals and unique attributes of product. Application of Finite Element Method is possible solution which accombines abilities and knowledge of user in consecutive to complexity of computatio. This enables a use of the most optimal solution. This thesis describes a principals of Direct-Current motor and its´ special design: Direct Inductor motor with extrinsic excitation (permanent magnests). It presents a operation of wiper motor in consecutive to wiping systém and fulfillment of engeneering standards. It also describes a principles of Finite Element Method in context to basics of simulation program FEMM. Main attention is given to creation of concrete model and to simulation of gauged exercise with wiper motor. Also there is a second simulation of motor, focused to different type of stator excitation. Findings of thesis is a comparation of theese exercises. Consecution of modeling in software environment is described. It compiles gauged excercise and interprets them.

DSP56800 microprocessor line usage for asynchronous motor control
Kukuczka, Adam ; Huták, Petr (referee) ; Klíma, Bohumil (advisor)
Tato diplomová práce pojednává o možnostech simulace a modelování elektrických pohonů na základě Bondových grafů. Je zde uvedena základní teorie k problematice. V práci jsou představeny modely stejnosměrného a synchronního stroje sestavené touto technikou. Dále je zde seznámení s Freeware knihovnou Bondových grafů BG V2.1 k programu MATLABSimulink. Za pomocí této knihovny byly sestaveny oba modely strojů. V poslední kapitole je uvedeno srovnání modelování na základě teorie Bondových grafů s modelováním v blokových diagramech.

Parameters identification of DC machine coupled model
Kraml, Aleš ; Huzlík, Rostislav (referee) ; Vlach, Radek (advisor)
This thesis deals with design and implementation of experiments leading to identification of parameters of a DC machine, creation of its model with coupled electrical, mechanical and thermal part. The first part describes various methods of modeling thermal resistance between body and ambient and the methods are compared. Furthermore, methods of identifying coefficient of damping and identification of moment of inertia are described. Second part of the thesis describes preparation and identification of resistance of the winding, inductance, heat capacities of rotor and housing and parameter c and measurement of damping coefficients. In the next part, the creation of a Simulink model of the DC machine is described. Furthermore, this thesis describes the algorithm for identification of parameters of an existing machine and the possibilities of using the model and identification in the development of a new machine. The next part assesses using the algorithm of identification and model as a basis for the creation of a virtual twin.
