Things to do[edit]

Yes - the difference/relation between adjustable speed drive and variable frequency drive is not at all clear from the two articles, where the terms seem to be used interchangeably. Hburdon (talk) 21:35, 22 July 2015 (UTC)

Images of adjustable-speed drives[edit]

I've tried to post a link to a webpage with several images of adjustable-speed drives, but for some reason, Wikipedia is not accepting the link. The images are directly related to the content of the article and demonstrate different applications of adjustable-speed drives. The link that would not post is found at http://emcsolutions.com/drive_gallery.html

Does anyone know why the link is not working? Webmaster emc123 (talk) 18:24, 14 February 2008 (UTC)

I agree, some sort of graphic is sorely needed, but I am hoping for more of a scientific conceptual diagram. The more abstract items, such as Eddy current drives in particular, need this. stuston (talk) 14:50, 26 January 2009 (UTC)

Lynch motor[edit]

Isn't the Lynch motor an adjustable speed drive ? 91.182.142.162 (talk) 08:22, 9 December 2010 (UTC)

I'm not familiar with them, but from reading the article (which needs tidying) I can't see why it's any more or less appropriate to a VFD than other types. As such I don't see it justifying a link from here to there, but quite possibly one from there to here. Motors suitable for electric vehicles (which seems to be the Lynch market) will tend to need VFDs, as they need good speed control, they wish to avoid the weight and losses in a CVT, and regenerative braking is useful too.
I'm guessing you know more about Lynch motors than I do. What's the issue that you're thinking about here? Andy Dingley (talk) 11:16, 9 December 2010 (UTC)
I don't now any more about the workings of Lynch Motors than you, but I was thinking that we could use this engine as a main presentation for the adjustable speed drive (ie we'll then need an image of it)

Oh, it's you. In that case NO.
Lynch motors are just one recent innovation in motor design. They're usable for variable speeds, but so are other motors too. They offer no particular ability for variable speed over any other motor. Nor are motor types particularly significant for their variable speeds: this is mostly the result of supplying them from an electronic variable speed drive (i.e. there aren't motors with a big "adjust speed here" knob that move the brushes or pole gaps around). As above, their relevance isn't commutative. Andy Dingley (talk) 11:18, 14 December 2010 (UTC)

overhauling load[edit]

  • term needs explanation --Treekids (talk) 16:21, 6 July 2011 (UTC)
How is it now? It's a bit of jargon that regularly gets used when talking about hoists. --Wtshymanski (talk)
