Auxiliary winding supplying the voltage regulator of synchronous generator
Hrtáň, Michal ; Hájek, Vítězslav (referee) ; Vítek, Ondřej (advisor)
The theme of this thesis is the design and verification of the auxiliary winding to supply the voltage regulator of the synchronous generator. The synchronous generator for which the auxiliary winding proposed is three-phase, low voltage with double layer random wound stator winding. The generator excitation is brushless with auxiliary rotating exciter. The auxiliary winding is designed for placement in the stator teeth, along with the main winding. The sizing of the auxiliary winding is derived from the power requirements the voltage regulator. Draft winding is validated analytical calculation and finite element method (FEM). The auxiliary winding has been implemented in the production of the generator. The Features of the auxiliary winding have been verified by measuring the by electrical testing room and the test results are evaluated.

Universal BLDC motor controller
Pijáček, Ondřej ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
This thesis describes the design of universal control unit for BLDC motor powered from airplane power distribution system of 28 V capable of driving motor up to 10 A. The maximal engine power is about 250 W. Important prerequisite is possibility of driving various motor size without needs of changing wiring board using only the configuration in the auxiliary memory unit. To control different motors is enough one unit with one program without any way to interfere to the unit itself.

Design and fabrication of the module used for the low voltage electric motors
Ludva, Stanislav ; Chalupa, Jan (referee) ; Šulc, Dalibor (advisor)
The aim of this diploma thesis is to design and implement a universal driver unit designed to control electric motors of small voltages – electronically commutated, DC and stepper. This involves creating topology and selecting appropriate components based on the required parameters. It also includes the manufacture of printed circuit board (PCB), soldering of the components and programming of the necessary functions. Thesis contains the analysis of three selected types of motors – the principle of operation, wiring and control. Testing of the control unit was performed at the end of the work.

Construction of BLDC motor with outer rotor
Smrž, Ondřej ; Vítek, Ondřej (referee) ; Huzlík, Rostislav (advisor)
This work is focused on the construction of the BLDC motor with outer rotor . Its mission is to become familiar with the design, basic relationships, applying this type of motor, the design procedure of magnetic circuit with permanent magnets, and then design the engine. Then there is a verification of designed motor finite element method. Finally, it summarizes the characteristics and parameters of the proposal and will compare the initial design with the other two designs, with some changes in the stator teeth.

Auxiliary inverters for electric traction
Polášek, Petr ; Pazdera, Ivo (referee) ; Červinka, Dalibor (advisor)
This thesis concerns with specified problems of an electric traction. It deals with the concept of module controlling EC motor of the voltage 24V and the current 100A. There are described possibilities and principles of controlling EC motor in detail. For controlling, the single-purpose IO MC33035, which is directly specified for it, is used. The thesis describes implementation of both testing and final versions of converter for a circulating pump drive of a cooling circuit in locomotives. The convertor is partly universal and can be used in other applications. According to the implemented convertor, a laboratory test and a model protocol were made. In the second part, the concept is described as well as the implementation of DC/DC conventor of output voltage of 24V and which is supplied by 12V battery. The specified output current is 4A. It is used for supplying of the controlling traction vehicle unit and is installed as a boost convertor which contains a resonance conventor. The presentation of measured parameters of the complete convertor is either a part of this thesis.
