I see someone is on their way to creating an article about asynchronous traction motors. That's good, but I believe that some ac traction motors are synchronous, driven by a variable- frequency drive. I *THINK* I've heard that this is the case with certain TGV generations.

Perhaps someone can chime-in with more details? (...or correct me?)

[edit] Ancient siderod-coupled traction motors

A recent editor removed the language calling siderod-coupled traction motors "ancient", claimingthat they date into the 1950s. Is this true? certainly in North America, they were all gone from any mjor applications long before that; I'd guess near the turn of the century.

Opinions? Facts?

That was me. I've seen photos of siderod equipped diesels from the 1950s on British railroads, which I don't consider ancient. slambo 14:49, Apr 13, 2005 (UTC)

Ahh, I think I see where we may not be communicating. Although I didn't write it explicitly, the model I had in mind was of a single carbody-mounted traction motor which was then connected to body-mounted driving wheels in much the same way as on a steam locomotive. These did exist, but I really do think they were ancent history. I think you, on the other hand, are describing an arrangement where a single bogie-mounted traction motor is coupled to multiple wheelsets/axles in the same bogie through side rods.

Have I now got it right?

If so, I'll edit the language in the article to make clear what each of us meant. :-)

That could be (I haven't had a chance to research the mechanics behind these locos), but I would avoid the use of the term "ancient". To me, ancient connotes a time period of more than 1000 years ago. slambo 15:52, Apr 13, 2005 (UTC)

The Swedish Dm3 electrics use the one-big-motor and rod method; and are still working. Meggar 04:05, 21 July 2006 (UTC)

"In the case of the TGV power units, each axle is driven by a motor mounted to the power unit's frame; a "tripod" drive allows a small amount of flexibility in the drive train allowing the trucks (bogies) to pivot."

Hello i would like point that this seams to apply to the motored trucks located right under the TGV power cars but, in all TGVs (exept "TGV pendulaire") there are two other motored trucks located under the first and the last passenger cars respectively, this is why the TGV pendulaire had to be coupled with a standard TGV to attain speeds higher than 220km/h(136mph) because, at that time alsthom did not developed motored trucks that could tilt. i wonder if these other motored trucks are powered by a "tripod" as well.

[edit] Vehicle electric motor

vehicle electric motor would treat car electric motors. --HybridBoy 19:55, 9 May 2007 (UTC)

I don't think that the traction motor article is large enough that it warrants another to address cars. Besides, noone calls them "vehicle electric motor"s, we simply call them motors or traction motors. "Electric vehicle traction motors" would me more appropriate, but again this article doesn't need to be split as it's not large enough and it describes perfectly the topic that it covers. Thank you very much for discussing this with the community before simply creating that article! --D0li0 08:17, 10 May 2007 (UTC)

That sounds like a good place to put a redirect that points here, though. --Atlant 11:37, 10 May 2007 (UTC)

What Electric vehicle traction motor? Although we already have the Electric vehicle (all vehicles) and Battery electric vehicle (passenger vehicles) articles. So in that light perhaps it would be Battery electric vehicle traction motor? But I think the WP:R policy is to not add unnecessary redirects with names that people don't commonly use, but I'm not sure. --D0li0 17:09, 10 May 2007 (UTC)
