Forms of Teaching
Lectures take place in two cycles. The first cylce lasts for 7 weeks with two-hour lectures and the second cylce lasts for 6 weeks with two-hour lectures.
ExamsWritten mid-term exam, final oral exam
ExercisesSolving of numerical examples related to the lecture topics.
SeminarsOn an example of a concrete electric drive from industrial practice it is required to calculate mechanical requirements of the working mechanism for the given dynamics of the drive, select the adequate drive and driving motor together with the switching and protection equipment, size the braking assembly (chopper and resistor).
