Hi, Tim Thank's a lot i understood all (i'm french and some time's it's hard to understand technique explanations) But this one is percfect for me.So i' will...
There is a toroid based axialflux design. It requires a laminated iron core for the torroid otherwise the flux from the magents would not cross the windings...
James, The server you gave isn't up. Try: http://repository.tudelft.nl/file/80792/161816 If not the same it is similar paper. chuck On Wed, 01 Apr 2009...
this is an impressive document! 270 page thesis. :-) Kenneth Long ... From: Chuck <comlink@...> Subject: Re: [axialflux] Toroid stator coil to increase...
hello is thar any specal way tha you place the coils in the stator and do you always wire then in searies or do you do parllel to is thar any books that show...
Every third coil is in series, there are three sets of 3 series coils in parallel. Get Dan and/or Hugh's book. Steve Spence Renewable energy and self...
Hi Dan, I have Hugh's book and yours should be here any day. I have been looking at Hughs book and dont quite understand how he is calculating "flux density B...
Hi Robert -- Hugh's math in there still relies on estimation....".......when the air gap is approximately equal to to the combined 'length' of the magnet, then...
...From new file (airfoil info) I really don't understand why NASA is limiting lift at tip to 1? ...And REALLY don't understand angle of attack tables! ...A...
Hello all, Has anybody or any company taken this axial flux design and "productionised" a generator. I would like to get my hands on a 2-5kW axial flux...
... ...I think your attitude is GREAT! as well as perfectly true. ...Would like to communicate with you directly so as not to bother people on this site,many...

Hey Everyone, I have been following along for a while now. Hope some of you can help me a bit. I am trying to build an axial generator to start between 90 and...
Okay, I have my tower. Now I want to start on the head. We have low average yearly wind speeds here, but it's a bit misleading as we generally have no winds or...
Hello from a new member and thanks for the great resource . I would like to know if anyone investigated into alternative measures to casting resin pooring to...
... Gabriele, If you are able to drill precision holes in accurate locations, it is possible to mount and hold magnets with bronze flat head nails such as...
Hi Butch, while I take my time translating some terms from your post( not english native tongue) I tell you why I was looking for a no-resin system. My idea...
First post- I think I have overlooked a fact in winding coils. I'm using 12 magnets/rotor, 9 coils, 3 phase series. Would the voltage from each of the 3 coils...
... Hello I'm a newbie , is anyone useing the 1//4 thick wedge magnets ?I think they are 2"tapered to 1" and what about the round magnets ?Thank you. Brian...
In the Homebrew Wind Power book, pg 210, Fig 16.14, a 2.5" hole is cut into the rear wooden hub and the blades. Does the cast wheel hub and bearing cover...
I have been playing with different designs in preparation to building my first alternator. This is 20 3/8 x1/2" long n42 magnets in 10 groups with 48 coils....
yes, each of the 3 coils in phase have additive voltage. why would you unwind to 2/3rds? how many windings did you make and what size wire did you use? Steve...
It's been some time ago I wound them, and my memory isn't very good, but I used # 18 or 19 wire and wound a test coil with something like 115 turns, and test...
for a 48 volt system, you need 144 turns or so. why did you pick 275 turns? that's way too many. Steve Spence Renewable energy and self sufficiency ...
