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.

Stray losses in magnetic material in the end of stator packet
Kopecký, Ivo ; Skalka, Miroslav (referee) ; Ondrůšek, Čestmír (advisor)
This thesis examines the magnetic field and magnetic flow at the end of the stator synchronous machine. This problem is solid using nonlinear magnetic resistive network, which is simulating by PSpice software. A simple model of stator, consisting of stator plates, air gaps and the two-thumbs, which hold the stator together. All of this is replace magnetic nonlinear resistive network, which is then divided into elements. According to these element is a simplified model solid and analyzed.

Magnetic field calculating of transformer by using conducting model
Bláha, Martin ; Skalka, Miroslav (referee) ; Kurfűrst, Jiří (advisor)
The paper deals with conductivE-resistive network. Use of this network is modeled transformer. The model is implemented in simulation program PSPICE and Simscape. To evaluace the results were used the values obtained using the finite element method. A simple model of the transformer has been replaced by rezistor network conductivity, which is divided into elements. According to these elements is a simplified model designed and analyzed
