Summary
The subject is focused on the understanding of the basic principles, design and operations of DC and AC electrical drives. The content of this subject is based on the knowledge of electronics, electrical machines, mechatronic systems and cybernetics.
Compulsory literature:
Recommended literature:
Additional study materials
Way of continuous check of knowledge in the course of semester
Checking test TEST No.1, TEST No.2 (see exercise)
Conditions for credit:
Obligatory participation in laboratory exercises.
In general 2 laboratory exercises are assessed max. 20 points. All measuring protocols delivery in right term = one week after measurement lesson
Pass through 2 control tests in regular terms. Test is assessed max. 10 points, i. e. max. 20 points from tests.
There will be confirmed just only 80 % of obtained points in the case of different term. One of these tests it's possible to repeat, but only with 80% of achieved points and there will be written the repeated test points!
Acquirement at least of 20 point from the 40 possible.
