Useless picture

Is there really any reason for having the picture of the track remains? There is no explanation in the article why this former track was remarkable. Frankly I don't see anything notable about it, and if it weren't for the caption I'd have no reason to think it's anything other than a big green field. --128.194.150.16 19:21, 2 May 2006 (UTC)[reply]

I absolutely agree and have difficulty in seeing any remains on the image. The miracle is that your comment was posted in May, and the image is still there, a monument to inertia. Perhaps if someone removed it, its supporters might become vocal...... Paul venter 13:37, 1 October 2006 (UTC)[reply]

Another good example

Is the TTC (formerly "People Mover") in Disney's Magic Kingdom (Florida)

Please feel free to be bold and add that to the article!

I thought the Bose suspension system was a good example of a unique linear motor use so I am adding a link under "external links".

Low or high acceleration?

Linear motors for space propulsion launch assistance are listed as high acceleration. I've just been reading about the Maglifter project, which is described as being low acceleration. The concept seems to be to have a long enough tunnel housing the track that low acceleration over such a distance is enough to approach escape velocity. DFH 21:48:36, 2005-09-08 (UTC)

Linear actuator

Is Linear actuator another name for a linear motor, or are they different? If they are the same, maybe a merge/redirect from that article is called for? -- Bovineone 05:13, 1 November 2005 (UTC)[reply]

It certainly sounds alike. I would also add that "Linear Traction Motors" and Linear Motors are the same animal. Piercetp 10:34, 5 June 2006 (UTC)[reply]

The description of linear actuator seems to make it clear that they are mechanisms driven by conventional rotary motors, whereas linear motors directly produce linear travel. Different animal.

Atlant 11:48, 5 June 2006 (UTC)[reply]

I stand corrected. But I am pretty sure that a linear motor and a linear traction motor are the same thing. Piercetp 18:58, 5 June 2006 (UTC)[reply]

That sounds right.

California Screamin'

I was wondering why California Screamin' was listed in the 'see also' section. While it is a LIM-based rollercoaster, it is not the first of its type. To make it completly fair, there would have to be a lot of rollercoasters listed in that section. WBHoenig 01:52, 13 August 2006 (UTC)[reply]

ART???

The photo caption says it is an "ART train", but there is no reference to "ART" in the article. What is ART? Ireneshusband 21:39, 14 December 2006 (UTC)[reply]

Not all Linear Motors are AC. The ART systems use Linear Motors that run from DC current.--Louiechefei28848888 21:30, 22 September 2007 (UTC)[reply]

Spam

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) 18:16, 28 December 2007 (UTC)[reply]

ROLLER COASTERS

What about roller coasters? They use LIM's too...

Nice diagrams Mikiemike, how about some explanation? — Preceding unsigned comment added by Ernest Ruger (talk • contribs) 20:31, 8 March 2014 (UTC)[reply]

Why use them?

The article fails to explain why you would use a linear motor in the place of a conventional one. There are obvious reasons in the case of a maglev, where there's no physical contact to power, but why does the ART/ICTS and the Japanese subway systems use them? There must be some advantage, but the article fails to point it out. They do point out the need for the reaction plate, which seems like a disadvantage. So I have to lay down this big stripe of metal, but I'll do that because the linear motor... what? Maury Markowitz (talk) 01:37, 31 July 2009 (UTC)[reply]

Re-Edit

Reading through this page, it seems clear that a more comprehensive article is needed on linear machines. I am a doctor of engineering, specializing in linear machines design and actively working in linear motor applications. I intend to undertake a fairly large re-write and expansion of the Linear Motor article over the next few weeks to include all linear machine topologies and categories. I don't want to step on any virtual toes however, so let me know if anyone has any objections to an extensive re-write of this article. Dr Tom Cox (talk) 09:38, 26 April 2010 (UTC)[reply]

Too Technical

This article needs to be put in layman's terms. While I can understand what it means, it would be vary hard, or next to impossible for the average joe to understand it. The introduction is the most important part to fix. Most people do not know what torque is, much less understand the physics equation. I do not know how to do this, so I will not attempt something i cannot do. Please help the article — Preceding unsigned comment added by 108.28.93.11 (talk) 16:22, 16 January 2013 (UTC)[reply]

Deleted photo

User:GliderMaven, why did you remove this image from the article? You did not give an edit summary. SpinningSpark 15:15, 20 October 2015 (UTC)[reply]

It just seemed unnecessary and overly difficult to understand what it was a picture of. Additionally, the layout of the article was fairly poor.GliderMaven (talk) 16:18, 20 October 2015 (UTC)[reply]

It seems more easy to understand to me than the only other photograph of an actual linear motor in the article File:Linear Motor of Toei Ōedo Line.jpg. SpinningSpark 17:53, 20 October 2015 (UTC)[reply]

I don't think that's a good picture either, but as always, feel free to improve the article.GliderMaven (talk) 20:41, 20 October 2015 (UTC)[reply]

Linear or not?

Should linear motors be described as involved linear motion, or not? It's possible that some might not be linear, if they were attached to curved rails or similar.
