This course covers the most commonly used type of electrical motor drives. Part I gives an overview of different type of electrical motor drive, type of load functions including the impact of using mechanical gears/transmissions. In part II some simplified models of the most commonly used power electronic converter topologies are presented. Control- and modulation methods are included as well. Part III in the course is devoted to DC drives. Mathematical modelling is performed, analysis of steady state characteristics and as well as dimensioning of current- and speed controllers. In part IV a general model of AC machines are presented. This includes introduction of space vectors, transformations and transformed mathematical models. In part V Permanent magnet synchronous is presented. Induction Motor Drives are discussed in part VI. In particular, the control principle- Rotor Flux Oriented Control – is covered in details.

Activities:

Lessons and exercises. The students will be divided into project groups to perform the projects. The exercises will cover dimensioning, analysis and simulation of specific drive applications. Two laboratory exercises are mandatory. The course is given in English. Postponed/repeated exams may be oral
