Electric motor drives can be seen as the synthesis of electric machines, power electronics and feedback control. The main emphasis of this course is the physical understanding of electric machines, since especially feedback control is covered in-depth in other courses in the study program. Power electronics is seen only as a block, which is able to process electrical energy to the form that is necessary for the application. The following subjects are treated: repetition of basics from electrical engineering, magnetism, magnetic circuits and transformers, DC machines, AC machines and the use of space vectors in the mathematical description, synchronous machines, asynchronous machines.
On successful completion of the course, the student should be able to
have an understanding of the physical foundation for electric machines and electromechanical energy conversion
have a basic physical understanding of the working principles for the most important DC- and AC machines
understand electric motor drives as the synthesis of electric machines, power electronics and feedback control
