The course is taught in English.
The aim of this course is to provide and explain the basic concept of the main electrical machine stationary and dynamic models. In addition, the use of these models will be deeply analyzed from the electrical drive point of view. In order to better link the theoretical part with the mechatronic practical ones information on electrical drives and static power converter will be include too.

The course includes simulation and laboratory activities both for stationary and dynamic behaviors of the electrical machines. The student will be able to check the simulation results with laboratory experiments. The simulations will be presented in the ambit of the theoretical lessons. For the laboratory activities the students are divided in groups.

The exam test is a written test with the scope to verify the student theoretical knowledge. The written test includes two questions evaluated 15/30 each. The final grade is determined averaging the two student answers. During the test is not possible to use any teaching documents such as books, notes, notebooks, phones, etc.

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.

The exam is a quiz test with the scope to verify the student theoretical knowledge.
The exam will be a quiz test with 16 theoretical questions.
Each question will have three answers
For each question, the system will provide the three answers in random way
The value of the right answer is equal to 2
The value of a wrong answer is equal to -1
With all the answers right the mark (total score equal to 16*2 = 32) corresponds to 30 Lode.
The system will pick up in random way the 16 questions from a repository of 75 questions
The test will be 30 minutes long (this reduces the possibilities to search the right answer)
The result will be available at the end of the test
The test is similar to the admission test.

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.
