... 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 ...
Hi Charlie -- Yes, the cast hub and grease cap do stick out that far in the front. There's a bit of extra space included by cutting into the blade roots also...
Hi Brian -- Generally wedge-shaped magnets are quite a bit more expensive than round or rectangular magnets of the same grade and mass, because the wedge is...
Our construction article on building your own wind turbine is finally finished. We are uploading an interview with Jim Juczak on the history of the turbine to...
Steve, thanks for the input!! When winding coils, I had no reference to go by, plus the book of Hugh's we were using only had 12 volt, as I recall. I built a...

If you really have wound the coils so that one will give you sufficient voltage then you could connect them in parallel instead of series. This might be a...
there are three sets of three coils. the three coils in each phase are in series. The three phases are connected at the center, with the end wire of each phase...
Let us assume John has essentially 3 pieces of wire, one for each phase. For each phase he has wound 3 coils and there are 2 lengths of wire between the coils...
Yes, it could be done that way, if he can make sure the number of turns on each coil is the same, and stacked in the same direction. Most of us use a Y wiring...
You sure about that Steve? One leg of all 9 coils would be connected at the center, and every 3rd coils opposite leg would be tied together and coming down to...
one end of a 3 coil series connects at the center with the other two ends of a 3 coil series. the other end of each 3 coil series goes to the 3 phase rectifier...
Yes. That is how folks are hooking them up normally. Why can you combine c1p1+c2p1+c3p1? Because the phase of those 3 coils are in sync. They each have a...
Then you would have to completely redesign the rest of the unit from blade size to diameter of alternator. You can do anything, but not everything will work...
I'm still following the posts, folks!! Appreciate the input. I'm leaning toward removing some of the windings since the stator is still not cast. We will first...
our 10 footer has stainless steel threaded rod, nuts, etc, but I need to paint the metal parts, magnet rotors, stator, etc. I've got oil based metal primer,...
Hey Steve, I just went to Wind Power 2009. Most of the windmill generators I saw had overlapping coils. Why does it seem like the commercial ones are wound...
