Homework before lecture 4
1- Go to the visualization tool from Chalmers, http://webfiles.portal.chalmers.se/et/Files/elkraft/Engelsk/start/index.html. Select "electric machines". Go to "travelling flux" and vary frequency, current amplitudes and direction. Can you write mathematical equations describing what you see? The answers can be found in reading the course literature. Have a look at the YouTube videos, to see real windings and how they are manufactured (fascinating!)
2- Read book
Alt. 1 course compendium chapter 3, defining the concepts you should understand and the notations we should use to communicate within the course.
Alt.2 [SEN] pp569-578 and pp209-216. No corresponding video lecture [DEL] :-(
Alt. 3 [FIT] pp188 (202) to pp213 (228).
3- Work on your list of technical terms and notations, checking the new introduced variables and finding their equivalent in your mother language.
