It's my experience that most of the heat is developed in the stator, not the rotor. I have not thrown a superglued magnet, as they are encased in resin after...
We use thin viscosity superglue to tack the magnets down, then cast vinyl ester resin around them. The superglue justs holds them in place for casting. We...
I've been trying to understand furling. I haven't been able to determine what actually is meant by 'tail weight' or 'tail tip weight'. Is it the actual...
It's all calculus, since the weight near the end of the tail affects furling more than the weight of the tail near the tower. What calculations did you...
Everything I have seen on the performance of various axialflux generators has been after-the-fact observations. Is there any kind of "cookbook" for designing...
Hugh Piggott's book, plus the articles the Dan's wrote for back home magazine give the cookbook approach. Anything else is experimentation. Steve Spence ...
... be aware of local/state regulations regarding steam pressure. Because inherent explosive nature of a boiler, they have been outlawed or severely regulated...
Hi John -- it's a bit of a black art. Our upcoming book "Homebrew Wind Power" does cover it some detail, it's too long to reproduce here. You'll want to know...
It is possible to get some 230v if u increase the winding and the wire size, or would that be too heavy ? As to me it seem logical if u increase the wire size...
Wild ac has varying voltage and frequency, so it's only useful for battery charging. There would be no point in winding the coils for 230v unless you have a...
Hi all, Quick into and then onto issues. I'm new to the group and have been lerking for a little. I'm also new to the world of wind power generation. I've...
Hi everyone, I am new to the group. I have just completed a 10 ft turbine with info available on www.otherpower.com. It works! But I made one mistake which is...
Howdy - The two important factors.... you should have a cutin speed of 140 rpm (150 is OK but getting a bit fast) - so, hook it to a 3 phase rectifier and look...
Hi Vivek -- we see this problem occasionally too, since we are building so many turbines. We get our steel parts water-jet cut out of 4x8 ft sheets of steel,...
Turn it flat on a Brake disk lathe. MG 1a. airgap between stator and magnets Posted by: "hoverindia" hoverindia@... hoverindia Date: Thu Oct 9, 2008...
Greetings, I'm hoping to learn more about rotor issues from the folks who know about these things ... I've seen rotors with notches cut out of them around the ...
Hammering steel flat is an art, if not a lost art. Making the rotors run with the proper run-out tolerance is probably impossible now that the magnets are in...
Thanks for your comments everyone, I made the magnet discs from 6mm steel plates and followed all the steps correctly. I think the cut in speed is a bit...
... That's what I suspected, thanks Steve. The reason I'm so interested in this is because I may have a source of inexpensive aluminum disks that are machined...
I have two generators rated at 3 and 8 kw, One (3kw)I turned into a PMG with an 8 magnet rotor and rewound the stator. I get some reasonably good voltage at a...
i was thinking of using truck bed coating from a spray can to coat the rotors. like the kind you buy from auto zone. i know its tough and durable and last a...
What is the minimum speed that a coil of wire has to move through a magnetic field in order to product useable levels of electricity? I do realize that more...
Hi guys, I am just wondering if anyone can tell me how to avoid the wires to get tangled when the wind generator turn on the mast. I have seen many wind...
