Course detail

Electric Drive Systems

FSI-VAP-K Acad. year: 2025/2026 Winter semester

The subject is focused on the issue of electric drives in automation. Attention is focused first on modern semiconductor elements used in electronics (inverters) for electric drives. Furthermore, the electric drive is defined, the mechanics, heating and energetics of electric drives are discussed. A considerable area is devoted to the control and regulation of electric drives. Here, basic knowledge from the subjects that were taught earlier is used, which is developed on a theoretical and practical level towards the issue of electric drives. Subsequently, the basic properties of individual electric drives are addressed. These are drives with direct current motors, with asynchronous and synchronous motors. The student will also gain knowledge about drives with special motors, specifically stepper and linear motors. Considerable emphasis is given to the description of mathematical and simulation models of motors and drives as well as the analysis of the cascade control structure. Part of the theoretical knowledge is also the practical verification of selected properties of drives in a laboratory exercise.

Language of instruction

Czech

Number of ECTS credits

5

Entry knowledge

Knowledge of mathematics, physics, electrical engineering, mechanics and the basics of automatic control is assumed, at the level of university courses completed so far.

Rules for evaluation and completion of the course

The laboratory exercise ends with a credit (it is awarded in the 13th teaching week). In order to obtain it, 100% participation in the exercises, activity in the exercises and preparation, submission and recognition by the teacher of protocols (reports) from all designated laboratory exercises are required. In case of absence of the student for the exercise, it is necessary to replace the missing exercise. The method of compensation is determined by the teacher or the guarantor of the course. Further details are communicated and explained to students at the beginning of the semester. Obtaining a credit is a necessary condition for participation in the exam. The exam consists of a written part followed by an oral interview. In the written part, the student processes the five assigned questions. Orientation in the studied issue is checked in the oral part. The evaluation of the written part, the oral part and the overall evaluation of the exam is given by the classification scale according to ECTS.

Aims

The aim of the course is to acquire theoretical and practical knowledge and experience in the field of electric drives. This is an addition to previously completed subjects of a general nature, which are expanded towards use in automation and informatics. In the sense of the above annotation and outline, the student will acquire extensive and comprehensive knowledge in the field of electric drives, which will enable him to be involved in the solution of various technical problems in an erudite manner in industrial engineering and electrical engineering practice.
