Obiettivi dell'insegnamento

The course gives the students the basic dictionary of the electrical drive. Thanks to the knowledge gained during the course, students will learn to compare the functional performances in relation with the different market segment, and to choose different components from manufacturer catalogues. In order to reach this goal the operating condition and the control algorith for different electrical drive will be analyzed, underlining the main constituting elements: the electrical motor, the power converter, the control algorithm and the power supply system. Furthermore different applications will be analyzed both in industrial and in transport field.


Risultati di apprendimento attesi

Lectures will provide the basis for electrical machine modeling, for electrical machine control and for power electronic understanding (Knowledge and understanding).

During practical exercises students will tacke some engineering problem: a resolution approach is proposed to the students who are asked the to execute it individually or in small groups (2-3 person). The proposed problems are typically related to the choose of devices from industrial catalogues (motors/inverter/batteries) or the the definition of the operational diagram from the nameplate data. (Applying Knowledge and understanding)

The achievemnts of both the above mentioned results will be verified during the final oral exam (Communication).
