Introduction - reminder of the general principles, configuration and basic operating characteristics of electrical machines under steady state. Presentation of the basic "transformation" relations by Clarke and Park (abc-αβ0 and αβ0-dq0) and the possibility of generalized representation of the various types of electric machines by using the "primitive" machine model. Application-validation of the transformations in the laboratory. Application of the generalized theory to the main machine types (direct current, synchronous, asynchronous, single-phase machines) and analysis of the basic transient phenomena (starting, short-circuits, load change, state-space block diagram representation and electrical machine drive systems). Application in laboratory and computer simulation. Introduction to the analysis of electrical machines by using space vectors.
