Description Electrical drives are electromechanical systems which enable electrical machines to function. Through theoretical analyses and practical laboratory exercises, students analyse and evaluate electrical machines and drives as well as examine various types of electrical motors and drive systems, their applications and control. Students conduct experiments on speed control, starting and braking systems, and dynamics of electric motors. These activities comprise essential knowledge and skills for students to be competent in the area of power engineering.
