The concept of electric motors used in vehicles
Polnický, Vít ; Repka, Martin (referee) ; Böhm, Michael (advisor)
This bachelor’s thesis deals with the description of electric drives concepts in current vehicles. In the first part, the basic principle of the electric motor is explained, and different types of electric motors are described in detail. In the next part of the thesis, the electrified vehicles are divided into three groups according to the power share of electric motor for vehicle propulsion. The groups are further subdivided according to the powertrain arrangement in the vehicle, indicating the advantages and disadvantages of each concept. In the third part, specific vehicles from each group are presented and compared in terms of performance, range and price. Finally, the concepts are evaluated and a possible development is outlined.

Children Terrain Electric Vehicle
Sedlář, Martin ; Rozsíval, Jan (referee) ; Blaťák, Ondřej (advisor)
The master’s thesis is focused on a conceptual design of a children terrain vehicle with electric drive. At the first part there are described children terrain vehicles rules, electric drives, regulations for a frame test and types of suspension. Then a suitable electric engine, an accumulator and other important parts of the vehicle are chosen. The following part describes the frame construction and its stress-strain analysis using Finite element method. The last part of thesis describes the suspension construction and front suspension kinematics solved in a multibody software. The result of thesis is a vehicle conceptual design created in CAD software Creo, supported by results of the stress-strain and kinematic analysis.
