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.
