Claw-pole automotive alternator design.
Szekeres, Vojtech ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The thesis deals with the alternators used in passenger cars, their desing, function and typical behaviours and characteristics and design. Alternators are specific with the trapezoidal shape of rotor poles, which produce a waveform similar to a square wave instead of a sinusoid. This is more desirable for simple rectification to direct current, which is used in the electrical distribution system of automobiles. Because of the shape of the poles, these alternators are also called the claw-pole. The design itself consists of creating an alternator in Ansys Maxwell software in compliance with real measured alternator. The results are compared numerically and also graphically.

Boarding House Amerika
Pokorný, Patrik ; Pilný, Ondřej (referee) ; Kalousek, Lubor (advisor)
This diploma thesis elaborates project documentation for the construction of building. The building is situated in outskirts of the town Velké Meziříčí. The boarding house for fooding and lodging with separated private zone and restaurant. Both parts connect entrance hall with reception and communication spaces. The lodging section is divided into three stories. Ground floor restaurant and salon with terrace on the second floor have south-facing oriented glazed curtain wall. That is the main part of building with stunning views on the ambient nature.

Design of gearing between transmission and alternator for drive of the superstructure of the heavy truck
Charouz, Ondřej ; Nohál, Libor (referee) ; Košťál, David (advisor)
This Bachelor´s Thesis presents an engineering design of gearing between transmis-sion and alternator for drive of the superstructure of the heavy truck. The gear ratio from engine to the output of transmission is 0,432 for normal constant meshing or 0,538 for reduced constant meshing. The performance of truck is 270 kW at 1800 rpm and torque 1850 N.m at 1000 +200 rpm. The thesis is focused on engineering design of location change of dynamo and not only to reduce the possibility of collisions between the chassis and the V-belt but also to make the whole construction simpler.

Accumulator Charger for Bicycle
Kufa, Jan ; Kubíček, Michal (referee) ; Šebesta, Jiří (advisor)
The aim of this thesis is to suggest a suitable way of charging mobile devices by using bicycle. In the first part of bachelor thesis there are discussed various options for charging the battery on a bicycle, described differences between the alternator and dynamo, and finally the different types of batteries. The second part describes in detail used blocks that were used in the engagement and the reasons of their choice. In the last section there are described the final parameters of the charger.

Universal controller for car or motorcycle dynamo
Picmaus, Jan ; Knobloch, Jan (referee) ; Červinka, Dalibor (advisor)
The thesis deals with the issue of design of an electronic controller of charging for historical cars using a dynamo. It contains theoretical analysis of the machine itself (dynamo) and analysis of a shunt wound dynamo and a seperately excited dynamo. It~is also focused on possible usage of a dynamo in various vehicles. The work compares industrially produced controllers with amateur manufacture as well as confronts their positives and negatives. All requests for the implemented controller are deduced from the analysis of the industrial and amateur controllers. The thesis consists of process plan of controller connection including the final working version and also the project and realization of a PCB as well as following description of putting the controller into practice and installation in the car. The thesis includes the project of current and voltage controllers, following adjustment and operation tests with use of the real device.

Weightlifting club Brno
Dvořáček, Jakub ; Struhala, Karel (referee) ; Jelínek, Petr (advisor)
The main task of the diploma thesis is to design a new nearly zero-energy olympic weightlifting gym. It’s located in Brno-Bystrc. It has two floors with a capacity of 80 people. The building is V-shaped with 165°. The load-bearing system is made of aerated concrete walls, reinforced concrete columns, slabs, and a foundation. The facade is designed from oxidated metal cladding and glass panels with metal framing. The building is covered by a green extensive flat roof. Heat water is provided by 2 ground-water heat pumps and one electric boiler. The whole building is heated/cooled by a combination of warm/cold floors and three HVAC units. The electricity supply is provided by photovoltaic panels, located on the roof. The third part of this diploma thesis is dedicated to automation in building designs, especially the usage of visual programming.
