Talk:Cogging torque

Not sure how this is done... but here we go. I'm an EE student but I may not understand the full extent of what's presented in the footnote listed in the article (to http://www.mullerpower.com/Research/Research.php) but it seems to be talking about permanent magnetic devices being perpetual motion machines. No mention cogging torque at all. A confused reference at best, misleading at worst. 134.153.11.147 (talk) 00:14, 4 March 2009 (UTC)
 * I've just deleted that link. Someone should find who've done this and ban him out. 193.107.65.243 (talk) 10:54, 29 July 2010 (UTC)
