Rotating field of a distributed symmetrical 3-phase winding: polygon of Görges
Animation is based on chapter 3 (p97) of the book Electrical Machines and Drives by Jan A. Melkebeek (ISBN 978-3-319-72729-5).
"The jumps of the mmf curve at each slot k correspond to the Dirac functions for the ampere-turns in the slot k."
Compare the mmf wave of this animation (with ) with that of the following animations (where and the mmf wave is the result of a stepwise linearly constant current layer): https://www.geogebra.org/m/azhgwttv and https://www.geogebra.org/m/tny9ykfg.
Please download the .ggb file and open with the Geogebra Classic 5 application (see https://www.geogebra.org/download) if the animation is too slow in your browser. The animation is designed to be opened on a 1080p screen and with "Make everything bigger" setting of Windows set to 100% (Change the size of text in Windows - Microsoft Support).
