Elektrické stroje na malé napětí. Zdroje elektrické energie na vozidlech – alternátory. Typy a provedení alternátorů, parametry. Předpokládaný vývoj alternátorů v krátkodobém a střednědobém horizontu – působení na magnetické a ventilační ztráty, použití magnetů, změna převodu, uložení na klikový hřídel a jiná zlepšení. Nekonvenční druhy alternátorů, startérgenerátory.

In every vehicle, there is a number of electric devices used for various purposes. The main source of electric current in a vehicle is an alternator, the combustion engine is turned at the required revolutions by an electric starter, every electric or electronic system contains an actuator, which is usually an electric motor or an electromagnet. The individual types of electric devices differ from each other particularly by the power output, dimensions, weight, location, and the way of connection to the driven equipment. The aim of the work: to analyse, experimentally, losses and efficiency in both groups of machines. To examine and design measures to reduce losses, test the designs on particular samples and draw up data for implementation. To solve some, still not sufficiently examined, losses, such as additional losses, specifying mechanical losses, etc. The final goal is the research, development and implementation of new generation of alternators with higher efficiency.
