Summary
Subject deals with characteristics of DC and AC controlled electrical drives in more detail.
The subject deepens the knowledge of electrical drives.
The content of this subject is based on the knowledge of the electronics and mechatronic systems.
Compulsory literature:
Recommended literature:
Way of continuous check of knowledge in the course of semester
Verification of study:
Checking test TEST No.1, TEST No.2 (see exercise)
Conditions for credit:
Obligatory participation in laboratory exercises.
In general 3 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 25 point from the 40 possible.
