 Code EEP351 Name Introduction to Electrical Drives Status Compulsory/Courses of Limited Choice Level and type Undergraduate Studies, Academic Field of study Power and Electrical Engineering Faculty Academic staff Leonīds Ribickis, Anastasija Žiravecka Credit points 2.0 (3.0 ECTS) Parts 1 Annotation Notion of electric drive, history, calssification. Mechanical characteristics of operation machines and motors. Electro-mechanical characteristics of DC and AC motors. Influence of parameters. Speed control in electric drive. Transient processes, calculation power indices, selection of motors. . Goals and objectives of the course in terms of competences and skills The aim of the course is to study mechanics of electric drive systems, influence of parameters on the characteristics of electric drive, methods of speed control, methods of transient processes calculations, calculations of power indices of the drives and aproach to the selection of motors for different regimes of electric drive operation. The students are required to describe and analyse systems of electric drives and to calculate and evaluate the influence of transient processes on the operation of electric drive.
