Summary

In the course students become familiar with dividing ot electric machines, with electrical materials and basic laws for electric machines. Basic principles of transformers and asynchronous machines and their operation characteristics are discussed. Students become familiar also with basic rules of winding. During laboratory excercises the operation states of electric machines are measured.
