Recommended previous knowledge: Circuits Analysis Automatic Control

COURSE AIM
The purpose of course it is to give the students a survey over the area of DC-motors and steppingmotors as systemcomponents and give knowledge so they can understand information in specialist literature, catalogues, and data-sheets. After the course the students can make well-founded choice among different alternativ for example then to choice motors in controlequipment. specialist literature, catalogues, and data-sheets.
