AbstractThis course introduces to different electric machine concepts and provides a deeper understanding of their detailed operating principles. Different aspects arising in the design of electric machines, like dimensioning of magnetic and electric circuits as well as consideration of mechanical and thermal constraints, are investigated. The exercises are used to consolidate the concepts discussed.
Learning objectiveThe objective of this course is to convey knowledge on the operating
principles of different types of electric machines. Further objectives are to evaluate machine types for given specification and to acquire the ability to perform a rough design of an electrical machine while considering the versatile aspects with respect to magnetic, electrical, mechanical and thermal limitations. Exercises are used to consolidate the presented theoretical concepts.
Content‐ Fundamentals in magnetic circuits and electromechanical energy
conversion.
