The course aims at providing to the students the basic concepts of the electrical energy conversion systems employed in transportation electrification, with a particular focus on hybrid and electrical vehicles. The systems under study will be the electrical drives for powertrains and the battery chargers. The electrical motors belong to the new generations of eMotors dedicated to electrical traction, such as induction motors, synchronous reluctance motors and internal permanent magnet motors. The course will provide also the basic concepts of vector control of traction drives, along with testing techniques to obtain efficiency maps and torque production maps.

In addition to classroom lectures, laboratory activities are planned. The laboratory exercises concern the analysis of the operation of an electric drive with internal permanent magnet motor.

Modalità di esame: Prova scritta (in aula); Progetto di gruppo;
Exam: Written test; Group project;
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Written test; Group project;
The exam consists of a written test of 150 minutes, containing multiple choice questions (24 points) and a question with open answer (6 points). During the exam, the use of books, notes or equivalent materials is not allowed. In addition, during the teaching students will be given a report to be elaborated at home, regarding the sizing of an electric drive and the design of the its torque control scheme. The report is rated up to 30 points. The final score is calculated as the weighted arithmetic mean between the written test (80%) and the score obtained for the report (20%). The rules of examination are described and discussed during the introductory class.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
