The ones I've been talking with manufacturers about have been asynchronous machines that still are not permanent magnet machines, they're inverter-controlled machines. I'm no motors expert but AFAIK they work by instead of generating against mains frequency with a gearbox they generate against a self-adjusting frequency generated from the grid frequency (so don't need a 'box) and then convert with an inverter back to grid-matched. At least that's what the manufacturer I was discussing with said. But he is only one of many. Using large rare-earth magnets of those scales would be vastly expensive but I suppose would increase the overall efficiency. </p> http://singletrackworld.com/forum/topic/why-do-people-like-windfarms/page/2#post-3239537 Sun, 04 Dec 2011 00:33:29 +0000 bigjim 3239537@http://singletrackworld.com/forum/ <p><blockquote>Don't the little ones work then ?</blockquote></p> <p>Yes they work fantastically well, a friend has a wee one on his farm and is astounded by the amount of leccy (and money as it way more than meets their needs on the farm) it is making.</p> <p>The Lammermuirs are pretty covered in them, when I drive on the road up to Whiteadder Reservoir it is always a surprise when they come into view.
