The study programmes with the given course

Objective of the course – aims of the course unit: New conception and essential information of Electric Drives / theoretical and practice /.
Objective of the course – learning outcomes and competences: The new information and crafts connect with contents electromechanical systems in this structure : control semiconductor power fed source + motors of different types + driven technology devices - practical and theoretical parts.
Prerequisites: The subject knowledge on the secondary school education level is requested.
Course contents (annotation): This new course link to courses of mechanic, theory of Electric machines and Power Electronics. Explain the principles and methods dimensioning of power parts structure of Electric drives. Electric drives play an important role as electromechanical energy converters in most production processes.Explain problems : Dynamics of a Mechanical Drive, Integration of the simplified Equation of Motion, Thermal effects in Electrical machines,structures with Separately Excited and Series DC machines, Control of Converter-supplied this type,Induction Motor + frequency converter,Variable Frequency Synchronous Motor Drives and Some Applications of Controlled Drives.
Teaching methods and criteria: Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.
Assesment methods and criteria linked to learning outcomes: Requirements for completion of a course are specified by a regulation issued by the lecturer responsible for the course and updated for every academic year.
