20801715 - MACHINES AND ELECTRIC OPERATIONS

The course has the purpose to describe the manufacturing features and the functional characteristics of the main rotating electrical machines, including dynamic models used for the study of the electrical machine behavior in electromechanical systems. It is expected that the student will acquire the ability to select the various electromechanical equipment used in industrial applications or in power systems for the electric energy generation. The course gives basic knowledge concerning the main configurations of the power electronic converters that are used for the control of power supply of electrical machines as well as it gives basic knowledge of the main algorithms being used in electric drives for control and monitoring of the machine performance. As a result, the course is targeted to give the know-how concerning how to select main design characteristics of an electric drive in connection with the functional specification of a given application.
