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

E405 (P211-0003) Electrical Engineering, Bachelor, ASPO 01.10.2005 , semester 4, 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).
30 class hours (= 22.5 clock hours) over a 15-week period.
The total student study time is 60 hours (equivalent to 2 ECTS credits).
There are therefore 37.5 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):
E101 Mathematics I
E102 Physics I

Learning outcomes:
This module prepares students specializing in power engineering for the study of electrical machines and drives and provides students taking other specialist courses with an overview of the most important concepts and relationships underlying conventional electrical machines.
After completing this module, students will have a solid understanding of the fundamental concepts of electromechanical energy converters, and in particular the steady-state performance characteristics of synchronous, induction and DC machines. They will be able to develop solutions to simple problems in the field of electrical machines.
