Summary
Student can determine the type of special electrical machine. He is master its function and its application in electric drive with reference to its electrically and mechanic characteristics.
The students they are in the subject cognizant of special electrical machines with small load.
These electrical machines are used in the computers, in domestic appliances and in car industry. They are synchronous, direct current, alternating voltage commutator, step and electronic motors. Content of study are principles of
functions of machines and their structural design.
