Applicability / Curricular relevance:
All study programs (with year of the version of study regulations) containing the course.

E511 Electrical Engineering, Bachelor, ASPO 01.10.2005 , semester 5, mandatory course
Workload:
Workload of student for successfully completing the course. Each ECTS credit represents 30 working hours. These are the combined effort of face-to-face time, post-processing the subject of the lecture, exercises and preparation for the exam.

The total workload is distributed on the semester (01.04.-30.09. during the summer term, 01.10.-31.03. during the winter term).
60 class hours (= 45 clock hours) over a 15-week period.
The total student study time is 120 hours (equivalent to 4 ECTS credits).
There are therefore 75 hours available for class preparation and follow-up work and exam preparation.

Learning outcomes:
After successfully completing this module, students will have acquired a basic understanding of electromechanical energy conversion and will know how to apply the fundamental laws of electrical engineering to solving problems involving electrical machines. They will also be able to use the knowledge gained to determine the key electromagnetic parameters in electric machines.
By studying this subject, students will gain a better understanding of the spatial and temporal relationships in electric machines and be able to draw parallels between different machine types. The methods learnt in this module provide a solid foundation for students taking more advanced modules in electrical machines.
