Aims

The aim of the course is to broaden students' knowledge in the field of electrical weapons production machines and systems in the areas of design practice, the dynamic behavior of drives and drive systems modeling. The goal of the subject is to achieve higher level of knowledge so that the students are able to apply the above mentioned devices and their components in their profession and to orient themselves in the wide market offer of individual manufacturers.

Specification of controlled education, way of implementation and compensation for absences

Controlled lessons are exercises. Exercises are obligatory, while attendance at the exercises is controlled. The student has to pass the missed lesson with another group if possible, or in exceptional cases, by completing homework on the topic. The level of this work is evaluated by the teacher.

Recommended optional programme components
