Animation is based on chapter 3 (p97) of the book Electrical Machines and Drives by Jan A. Melkebeek (ISBN 978-3-319-72729-5).[br][br]"The jumps of the mmf curve at each slot k correspond to the Dirac functions for the ampere-turns in the slot k."[br][br]Compare the mmf wave of this animation (with [math]q=25[/math]) with that of the following animations (where [math]q=+\infty[/math] and the mmf wave is the result of a stepwise linearly constant current layer): [url=https://www.geogebra.org/m/azhgwttv]https://www.geogebra.org/m/azhgwttv[/url] and [url=https://www.geogebra.org/m/tny9ykfg]https://www.geogebra.org/m/tny9ykfg[/url].[br][br][i]Please download the .ggb file and open with the Geogebra Classic 5 application (see [url=https://www.geogebra.org/download]https://www.geogebra.org/download[/url]) 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% ([url=https://support.microsoft.com/en-us/windows/change-the-size-of-text-in-windows-1d5830c3-eee3-8eaa-836b-abcc37d99b9a]Change the size of text in Windows - Microsoft Support[/url]).[/i][br][br][i][b]Any and all feedback is welcome and can be sent to [url=mailto:timon.dewispelaere@kuleuven.be]timon.dewispelaere@kuleuven.be[/url].[br][br][/b][/i]Please be patient while moving the sliders: geogebra is calculating!
