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.

Attendance
Regular attendance at lectures, practical sessions, and laboratory activities is strongly recommended, given the application-oriented nature of the course and the close integration of theoretical content, simulations, and experimental validation.Type of evaluation
The final assessment consists of an oral examination covering the theoretical, methodological, and application-oriented topics addressed during the course. The examination assesses understanding of converter and electrical-machine operating principles, the ability to derive and interpret dynamic models, knowledge of control strategies, and the ability to discuss simulation and experimental results critically. The evaluation takes into account the accuracy and completeness of the answers, appropriate use of technical terminology, the ability to connect the different drive subsystems, and the degree of autonomy demonstrated in solving analysis and control problems. teacher profile teaching materials
