Learning outcomes of the course unit
The acquired knowledge and skills enable students to master the engineering design of the electrotechnical equipment of production machines and equipment at high professional level and to understand the internal processes taking place in these facilities.
Prerequisites
Differential equations, Laplace transformation, fundamentals of mechanics dynamics, fundamentals of theory of electric machines and drives, schematics and functions of electric energy converters, fundamentals of electrotechnical equipment of production machines.
Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is suplemented by practical computer exercises.
According to the possibility of teaching can be organized lectures for students by practitioners and excursions to companies focused on activities related to the course content.
Assesment methods and criteria linked to learning outcomes
Conditions for granting the credit:
1. Passing all exercises (100% attendance),
2. Processing the assigned project.
Exam: The exam is combined, has a written and oral part and examines the complex knowledge of the subject.
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.
