Electric Drives (2 cr)

Evaluation scale

0-5

Objective

Familiarize yourself with industrial electrical drives. The emphasis is on basic structures and dimensions. Studying in this course requires basic knowledge of electrical engineering (calculation skills of DC and AC circuits and knowledge of components). You can apply what you have learned here, for example, in other courses in this module.

EUR-ACE ENGINEERING PRACTICE
You can the basic calculation of connected three-phase circuits and its concepts. You know the basic structures, components and protection principles of power supplies. You understand the basic structures and operating principles of electrical machines and are aware of their most common uses. You will have a basic knowledge of the design, operation and control of AC machines.

Further information

The course has an 80% attendance rate. Attendance is monitored. Absences are agreed with the teacher for justified reasons. For example, cases of illness or otherwise demonstrated competence. The assessment criteria will take into account the student's active participation in the course. For example, demonstration of competence by completing a proportion of the tasks specified by the teacher.
The student must sign off the course feedback as having been given (assignment in Moodle).

The exam and the exercises to be returned determine the grade. Self-assessments are mainly done by means of learning tasks. The assessment decision is based on the competence demonstrated in the exercises.
