A single plate will work but not as well as you would think, even with stronger magnets. At one time I had the formula for field strength vs. distance given to...
Excellent input. Thank you for your info. You have talked me into a dual rotor, now I just have to figure out some numbers. I am making a large diameter...
Hi Jason -- We use a single magnet rotor on our 7 foot machine. It's not a very good use of magnetic material -- the magnetic circuit is not complete. However,...
Hi George -- we decided NOT to do pre-orders for this book....we don't have a firm availability date, but it should be sometime in October. Don't worry, there...
I'll leave those questions for the experts, but I seem to recall needing 4 magnets for every 3 coils to prevent\reduce cogging. What I did to figure out my...
Agian thanks for your help. I will be using about 40 or 50 magnets and I will be using the overlap method of the coils. So I thought I could use one...
Hi guys, Does anyone know where I can get a maximum power point tracker unit that I can put between the output of the rectifier and the battery? I'm sure this...
Hi Jason and All, Just want you to know vertical rotors are very ineff, less than 10% usually vs up o 56% for a 3blade unit of the same area. It's also much...
Hey Dan, did you and the other Dan finally decide it was finished, smiles? Congratulations, I love mine just the way it is, (Xeroxed.) Thank you I'm making...
I understand about the Vertical inef issues but I am bound by my Zoning and Association rules with towers and noise. I am trying out a VAWT that is 36"D x...
Hi Jason - this is supposed to be a discussion of axial flux alternators I think so this is maybe getting a bit off (Sorry). Some comments though.. ... A...
Folks normally use 3 coils/every 4 poles - not so much about cogging, but it offers a nice simple way to achieve 3 phase that, done reasonably well can be...
That sounds about right. I dont think, unless you live in a very humid place and are very worried about rust, that thick walled pipe makes much sense for...
Hello All Well I guess I'm going to sell my SW4024 with conduit box and Remote program to run on your comp. with the wire hookup. I was told by the service ...
Greetings, I just completed the chiptso wind genny and I am just a little disappointed. The cut in speed for the blades are better than 20 mph. Does anyone ...
Low cut-in speed blades = build longer blades and get a larger swept area. That's the only way to do it. Make sure the turbine alternator can handle the bigger...
my first set of rotors came well, but I am afraid I put a lot of resin on it, could you tell me if 2mm of resin over the neodymiums would significantly afect...
Dan, Thank you so much for your comments. I am learning allot, which is why I joined the group. I don't want to break any group rules by talking about my...
That circuit will not work well for wind, as there is no diversion capability. Wind can't be "turned off" like solar, the power needs a place to go. Steve...

I have the new XW4024 in place now, got my conduit box yesterday and the guy show up yesterday to look at it and gave me the ok to feed back and 2 weeks to get...
One thing nice now it's 240 AC now so nice from my SW4024 was 120AC but still at 60 amps. It was nice of my insh. Comp. to give me a new one to my SW4024 was...
