Spam[edit]

A link to electojects.com has been repeatedly added to Stepper motor, Electric motor and Brushless DC electric motor by Special:Contributions/217.53.109.235, Special:Contributions/82.201.156.201, Special:Contributions/217.53.107.168, Special:Contributions/217.53.16.164, and others.

The link in question is registered to Abdoh Ali Mohamed, Hay Swesri, Nasr City, Cairo, Egypt.[1]

I wonder if the four IP addresses listed above have any connection... Naw, couldn't be. [2][3][4][5] Egypt is a big country. Must be a coincidence.

I'm going to start patrolling wikipedia for any links to electojects.com or redirects to it and deleting them on sight. If they come back, I'll move to blacklist the address. Mdsummermsw (talk) 18:30, 28 December 2007 (UTC)[reply]

I have no connection with electojects.com but I think it looks quite useful and it doesn't appear to be selling anything. Biscuittin (talk) 15:17, 3 January 2012 (UTC)[reply]

Section "Repulsion"[edit]

The text refers to a diagram but it doesn't seem to be the diagram shown in the section. Where is the axis KK? Where are conductors 1,2,3 and 13,14,15? Biscuittin (talk) 15:26, 3 January 2012 (UTC)[reply]

I have deleted the irrelevant text and moved the diagram to the relevant section. Biscuittin (talk) 16:51, 3 January 2012 (UTC)[reply]

I started to read this entry and found it extremely confusing, despite the fact that I have written a university-level textbook on electricity and magnetism. (I am a physicist, not an electrical engineer.) Part of the problem is that there are figures without captions, and the connection between figures and text is not clear. Likely the authors who started this article were so close to the subject that they just did not realize how much they knew relative to newbies. Anyway, I was very disappointed to find that, yet again, I found no clear explanation of this subject. WMSwiki (talk) 18:59, 16 July 2021 (UTC)[reply]

Questions[edit]

There are some unanswered questions. Does a repulsion motor require a low-frequency supply, like an AC series motor? How good is the efficiency? Why has it dropped out of use? Biscuittin (talk) 20:17, 3 January 2012 (UTC)[reply]
