Aim
Considering most mechanical constructions are dependent on electric drive and/or control, the aim of this course is to give the mechanical engineering student essential knowledge of electric drive systems. The aim of the course is to make the student a competent user of electric drive systems. The student is shown characteristics, limitations, and possibilities for various combinations of electric machines and power electronics for control. The laboratory exercises are designed to be of help to understand basics and to give knowledge of practical handling and measurement on an electric drive system.
