Substituting circuit of an induction machine
Běloušek, Radim ; Cipín, Radoslav (referee) ; Patočka, Miroslav (advisor)
Although induction motors are the simplest and most working reliability machines, is the identification of the parameters of their substituting circuit very difficult. There is solved the identification of the parameters of the substituting circuit in the T-network and ? –network in this work. The work also includes the proposal of magnetic circuit of the induction motor, the calculation of magnetizing and leakage inductances and resistances of the machine. The conclusion of the work is devoted to the sensitivity analysis of current and torque characteristics of induction motor upon the change of the single parameters of the substituting circuit.

Design of dual regulated power supply
Moštěk, Jiří ; Kubíček, Michal (referee) ; Brančík, Lubomír (advisor)
This bachelor thesis deals with design and construction of a symmetric stabilized power supply provided with an adjustable electronic current fuse. The concept of source is chosen as a linear with two-output voltage ranges. The first range is possible to regulate the voltage from 0V to 20V with current limit 2mA – 4A or 2mA – 8A. The second voltage range allows you to adjust the output voltage from 0V to 40V with current limit 2mA – 4A. Included in this bachelor thesis is the simulation source, testing in non-soldering field, PCB design, commissioning, draft cooling and design of structural solutions. At the end of bachelor thesis are given the results of measurements laboratory resources and photos.

Measurement of DC and EC motors characteristics
Chlebný, Radek ; Cipín, Radoslav (referee) ; Vondruš, Jiří (advisor)
The Bachelor thesis deals with commutator direct current motors and electronically commutated motors of company Maxon motor AG. The first part of its deals basic structural elements and focuses on the characteristics of these engines, such as lifetime, revolution properties, efficiency and control methods. The thesis deals with properties, principle of operation and construction of hysteresis brake. Another important theme is improved by the construction of the dynamometer. The last part contains the actual measurement of DC commutator motors assigned Maxon RE and Maxon S, which are loaded with hysteresis brake and final evaluation measurements comparing measured values with the data producer.
