Incorrect photo?

I'm not entirely sure, but I don't think the disassembled motor in the picture is a reluctance motor; it looks like a shaded-pole asynchronous motor to me. The two short-circuit copper windings for the shaded poles are clearly visible, and the rotor looks like a fairly typical skewed squirrel cage. Also, the use of such a motor is very common for small fans for mains operation. Because I'm not quite sure, and for the lack of a better photo, I've left it in place. 80.56.185.91 (talk) 13:02, 29 November 2009 (UTC)[reply]

Me neither. Definitely a shaded-pole stator, but the rotor looks like it might have 3 salients all encased in die-cast pot metal - this would make for quite a variation in reluctance as the motor turns. I, too, would like to see a more classical demonstration of the device but I think this one qualifies. --Wtshymanski (talk) 15:35, 29 November 2009 (UTC)[reply]

I'll remove the photo File:Reluctance machine.jpg now. Nillerdk (talk) 07:47, 7 April 2010 (UTC)[reply]

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) 18:23, 28 December 2007 (UTC)[reply]

asking the construction of reluctance motors

What is the construction of reluctance motors? —Preceding unsigned comment added by 213.55.94.34 (talk) 09:00, 17 January 2008 (UTC)[reply]

asking for source of "applications" section concerning the jet engine

That material is highly specific to a particular manufacturer/application. It should include a citation as such.

Control engineering magazine (www.controleng.com)[Reed Business Pubs] March 2010 p38ff has a nice article by Frank J Bartos, PE, that mentions www.emerson.com, www.emetron.com, and www.rockymountaintechnologies.com (drive and motors) as sources of controls and motors of this type.

incomplete type description

The introduction refers to 4 types of reluctance motors, but the motor types section only describes two of them. —Preceding unsigned comment added by Olivier.rieux (talk • contribs) 13:38, 15 June 2010 (UTC)[reply]

generator

Can a switched reluctance motor be driven "in reverse" as an electric generator? A switched reluctance motor doesn't have any permanent magnets, so it is hard to see how it is possible -- but I know that some of the biggest electric generators somehow work fine without any permanent magnets. --68.0.124.33 (talk) 03:53, 16 March 2011 (UTC)[reply]

I've never heard of a switched reluctance generator, aside from the weird high frequency alternators used for radio in the elder days; but generators as used in power plants have electromagnet fields. --Wtshymanski (talk) 13:40, 16 March 2011 (UTC)[reply]

Yes. Just do a web search on "switched reluctance generator", and you'll get plenty of hits... EdwardEditor (talk) 22:16, 10 December 2012 (UTC)[reply]
