| 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. |
| Learning Outcomes of the Course Unit |
|---|
The main aim of the subject is to obtain theoretical knowledge of the area of electrical drives and practial skills with their applications.
The obtained information creates the knowledge base of bachelor, who applies the electrical drives.
