Course detail

Electrical Engineering of Production Machines

FSI-GEV Acad. year: 2019/2020 Summer semester

The course makes students familiar with basic problems of electric equipment used in production machines and equipment. The following topics are dealt with: General requirements regarding electric equipment of production machines and explanation of principles of activity of the most important action elements of spindle drives and supports (electro-magnetic elements, static and dynamic characteristics of DC motors, motors with electronic commutation, asynchronous, synchronous and step motors, mathematical models, methods of control and relevant feeding circuits. The students will learn of the methodology of keeping electro-technical documentation.

Learning outcomes of the course unit

The knowledge and skills acquired in the course enable students to manage the construction design of current production machines and equipment on a high level.

Prerequisites

Differential equations, L-transformation, fundamentals of mechanism dynamic, fundamentals of theory electric machines and apparatuses, schemes and function of electric energy converters.

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 laboratory work.
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 a course-unit credit award: 1. Attendance at exercises (100% participation), working out laboratory protocols and satisfying of pre-set conditions of continuous study checking (stated at exercises). 2. Working out a home assignment. Exam: The exam is combined with written and oral part and it verifiess the complex student`s knowledge acquired in the course.

Aims

The aim of the subject is to make students acquainted with the current situation and possibilities provided by the technical machines equipment applied to production machines and equipment. The task of the subject is for students to acquire knowledge on such level so that they are able to apply the above stated equipment and its components in their professions and will have a clear idea of what producers offer on the market.

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

The controlled lesson is an exercise. Exercises are required. The attendance at exercises is recorded and the level of knowledge is tested by solving practical assignments. Students are required to compensate missed lessons with another group of students or – in exceptional cases – by working out an assignment regarding a relevant topic. A teacher evaluates the quality of the assignment.
