The course focuses on the principles of designing electric drives with AC motors in different ways and different types of load, reliability, design for explosive environments and for special purposes and the necessary technical documentation. Students learn the basics of electric traction drives for trams in public transport systems, electric locomotives, as well as the systems of hybrid cars and electric vehicles.
Conditions for obtaining the credit: attendance according to the study rules, active participation in seminars, submission of protocols from laboratory tasks, approval of protocols from laboratory tasks by the teacher.
