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

E908 Electrical Engineering, Master, ASPO 01.10.2005 , semester 8, 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).
75 class hours (= 56.25 clock hours) over a 15-week period.
The total student study time is 150 hours (equivalent to 5 ECTS credits).
There are therefore 93.75 hours available for class preparation and follow-up work and exam preparation.
Recommended prerequisites (modules):

Learning outcomes:
After successfully completing this module, students will have a fundamental understanding of how to analyse transient responses in electrical machines. They will be able to describe an electrical machine using a linear or a nonlinear dynamic model and will be able to compute the machine’s dynamic behaviour in the time domain. They will be in a position to use their knowledge to calculate dynamic parameters of electrical machines and to develop and document solutions to specific technical problems in the field of controlled electrical motors and drives.
