intro:
DIY 1000 watt wind turbine
We built a 1000 watt wind turbine to help charge the battery bank that powers our offgrid home. It's a permanent magnet alternator, generating 3 phase ac, rectified to dc,
and fed to a charge controller. The magnets spin with the wind, the coils are fixed, so no brushes or slip rings necessary.
step 1:
Build the magnet disks
We had 12" steel disks hydro cut. We cut a template for mounting the magnets. Then we mounted 12 grade n50 magnets around the outside edge. We then built a form,
and poured the resin with hardner.
http://www.instructables.com/id/DIY-1000-watt-wind-turbine/
step 2:
Build the coil disk
We wound the nine individual coils, soldered them in a 3 phase wye configuration, and encased them in resin. We used 35 turns of 2 parallel strands of 14 gauge
enameled wire for 12 volts. Use 35 turns of single strand for 24 volts.
http://www.instructables.com/id/DIY-1000-watt-wind-turbine/
step 3:
Build the bearing assembly
Two Harley Davidson wheel bearings are inserted into the pipe, with a smaller pipe locked between them to keep them in place.
step 4:
construct the blades
The blades are 2" x 6" pine, cut at 10 degrees on a table saw, and sanded into a rough airfoil. Not perfect, but close enough.

Coils.
I haven't a clue. How do you calculate what you need?
I am using N42's which are not a powerful as yours and mine are small disc ones so I would need a smaller gauge wire and my coil size is limited.
I would like to wind coils to optimize current output and also give off at least 12 volts.
How can I do that?
I have been looking at coil winding but all I find are manufacturers selling services or pre made coils.
If you know where I can go to get this information, I would appreciate the link.
says:
Any help on this?
How many turns of SWG26 does it take to get any size able voltage? 35 turns may get 24 volts out of SWG14 wire but it don't produce much when I wind
a coil with anything smaller.
says:
The number of turns determines the voltage, the size of the wire determines the current that the coil can produce. 35 turns gets you 12v, 72 turns
gets you 24v when 3 coils are in series. We have more info on our discussion group at
http://tech.groups.yahoo.com/group/axialflux/
says:
Being new to becoming "green", I would like to ask, at the risk of sounding totally ignorant, how do you get your house "off-grid" in the first place? I am
assuming "off-grid" means you are no longer connected to any power or gas companies? Please correct my assumptions if wrong! :)
says:
Sep 25, 2008. 5:47 PM
You're right,"off grid" does mean you are not connected to the power company.
Usually houses that are off the grid are houses that are just too far away for it to be feasible to run power lines. Houses that are connected to the grid can
use solar panels and wind power to generate their own electricity and sell back to their power company (if the company allows "net metering"). Some
states have programs in place to compensate you for the power you create even if your power company doesn't have "net metering". The set up is very
expensive, you not only need solar panels or a wind mill. You also need an inverter which changes DC to AC and synchronizes the power back to the
grid. Does anyone have plans for building an inverter?
says:
as i remember "truley free electricity" on the giant instructables.com had an inverter design on the bottom
says:
I built on a road that has no power lines or gas lines. I make my own power, and although I use propane right now, I'm building a manure digester to
make bio-methane as a replacement.
says:
Manure digester? I know what it sounds like it means. ;) Lots of manure around the area I live in....please tell me more. Have you found it hard trying
to do this on your own? Do you have a blog telling about it?
http://www.instructables.com/id/DIY-1000-watt-wind-turbine/
says:
Sep 6, 2008. 10:56 AM
A methane digester is a simple tank that manure and crop residue gets poured into (slurry with a 30:1 C/N ratio) and digested anaerobically for
40-50 days. Gives off a gas that contains methane. Our blog is at
We have lots of help from our "community".
says:
it can also be fed into an ng engine (lawn mower with CNG kit,maybe?) to make electricity
says:
Sep 6, 2008. 12:16 PM
Thank you very much! :) Both for the information about the methane digester and the link!
says:
Sep 6, 2008. 12:30 PM
Sorry, meant to say manure digester! :)
says:
How thick were the magnets???
says:
Sep 12, 2008. 1:10 PM
1.2" thick, 1" wide, 2" long.
says:
Sep 15, 2008. 8:47 AM
So your magnets are producing a pull of 195 lbs?? Is that about correct??
says:
Sep 15, 2008. 9:11 AM
Could be. We didn't test that parameter. Sounds about right for a N50 of that size.
says:
Sep 25, 2008. 5:56 AM
So how are the magnets lined up to each other? The plates they are mounted to are pulling each other? right?
Also, does the proximity to the magnet make any change to the amount of voltage or current?
Any idea on what the "Optimal" placement is in relation to the coils?
I notice on your build that you have a gap, can you remember how large it is?
says:
Sep 25, 2008. 6:17 AM
The magnets are arranged "N" up, "S" up, "N" up, etc.
The plates do attract each other, but there is a 1/8" gap between the plates and the rotor. The closer the magnets are to the coils (without
rubbing) the more power you make.
says:
Sep 24, 2008. 3:34 AM
there is no detailed explanation about construction
says:
Sep 22, 2008. 2:30 PM
This is a really great setup but you should give much more detail into how to build it.
says:
Sep 20, 2008. 6:13 PM
I see your solar panels in the background are they the 45 watt harbor freight
setups?
says:
Sep 21, 2008. 6:31 AM
Yes. I no longer have those. I know have five 110w mitsubishi panels, and 6 sanyo 200 watt panels on order.

says:
1- here is fiberglass but not in cloth style, that is in powder style. is it right to use that?
and is it possible to we donot use fiberglass?
2- i found that magnets N50 in a website but that are in so high price, can not effort that and now i attach you some pictures of them, check it if it is possible
to use:
BX041-
1" x 1/4" x 1/16" thick
Grade N50 - Nickel Plated

as long as there is a N side and s side, any of those will work, but your coil shape will need to be adjusted. The round one would be the less desired. the
fiberglass cloth is to give the coil pack strength. as the coils do not spin, you may get away without it. Not sure.
says:
Sep 16, 2008. 2:34 PM
Where do you get your magnets? And how much are they?
says:
Sep 16, 2008. 6:12 PM
should be able to help you.
says:
How do you keep the tower from winding up the power leads? You know as the wind changes direction, and the generator swings to account for the change,
it would eventually wind up the leads. Do you have a was to prevent that? I am trying to find a brush pivot that would allow that to spin freely.
says:
Sep 16, 2008. 2:02 PM
Every month I go out and untwist them. They don't twist up to much.
says:
How Long are the blades??
says:
Sep 16, 2008. 1:51 PM
Five foot.
says:
Sep 15, 2008. 9:08 PM
1- What kind is that white color thing which you use on coil?
2- what is that which you use in second picture?
help me
http://www.instructables.com/id/DIY-1000-watt-wind-turbine/
says:
Sep 16, 2008. 6:02 AM
The white cloth is fiberglass, which gives the coil pack strength. The second picture shows us filling in casting defects with bondo, a body putty used on
cars.
says:
Sep 15, 2008. 5:11 PM
How much do you think this project would cost? And do you have more information on the actual mounting of the turbine on a post or something?
says:
Sep 15, 2008. 6:16 PM
Our turbine cost about $500. You can see the mounting pictures at

Hello,
again about magnets,
i found some magnets and i attach its picture,
1- Can i use them?
2- what kind liquid i can use for to tight the magnets on iron plate?
please check it and inform me,
i really love to fix and build a turbine. please help me
says:
Sep 15, 2008. 6:28 AM
I have no idea what kind of magnets those are. For maximum output, you want neodymium magnets, but others will work, just less output. For low rpm
application, superglue tend s to hold up pretty well. We have gone to bored and countersunk magnets, and use brass screws. This is done during the
manufacturing process.
says:
Sep 15, 2008. 8:45 AM
Another process that works is to cut a recess on the rotor to put the magnets on. Then cover with 2 part epoxy. Not to hard and fairly cheap.
Source is otherpower.com for that info.
says:
Sep 14, 2008. 8:50 AM
Does anyone know where I could order or get these 12" flat round plates at 12" x 1/8" thickness. Thanks for the help :)
says:
Sep 14, 2008. 2:12 PM
find a local welder / metal worker. We found one with a hydro cutter.

says:
Hi, I am in the process of building a wind turbine but would like to keep the AC. By using diodes will i automatically change the current to DC. Are there
diodes available that wont change the current to DC? Can the wye configuration be wired in a different way, say without diodes, to have the voltage output
remain as AC. Thanks in advance, you have a great site.
says:
Sep 14, 2008. 1:36 PM
diodes turn ac into dc. That is the purpose of diodes. if you don't install the diodies, you get three phase ac, where the frequency and voltage are
dependent upon rpm. these two parameters will be all over the place unless you are in a fixed rpm application.

Hello , This is abdullah from Afghanistan,
i found your web site and want to build a wind generator, but i need your help,
here I try much to find some magnets like used in the picture but can not found, now i has some question please answer it,
1- If i use the load speakers magnet, is it work?
2- Coil: With out the liquid which you mentioned in your instructor, Can i use any anther one , if YES then please tell me what.
iam in wait for your positive replay,
thanks
says:
Sep 14, 2008. 6:13 AM
melted plastic would work as a replacement for fiberglass resin. magnets can be found in hard drives, wire can be found in motors and alternators.
says:
Sep 13, 2008. 4:56 PM
does the size of the coils affect output power in anyway? I made a coil just to see what one is like. It's a 24v one so it has 72 turns.
The internal hole is about 12 by 31mm and the outside is about 48 by 60mm and is about 20mm high. sorry if its mm but divide by 25.4 to get inches. great
project by the way!
says:
Sep 14, 2008. 4:53 AM
the coil size is determined by the magnet size. If it doesn;t pass the mmagnet correctly, output suffers.
says:
I teach at a middle school in MN. We are thinking about trying to build a generator to place on top of the building. Any pointers for us??? Remember they are
8th graders that will be tackling this.
Cool site, and great info.
says:
You won't get much output on a roof, and vibration will be an issue. Get your shop teacher involved, and you should have few problems building one of
these. Get the free (with subscription) 4 issue step by step hand holding instructions at
says:
Sep 12, 2008. 4:01 PM
I am the shop teacher for the Middle School. I teach 7th and 8th grade students. Starting this year we are focusing on renewable energy, mainly solar
and wind. vibrations is an issue, but can be minimized by proper balance of the motor. As far as mounting on the building, we do not have a yard in
which to put it. The building is 4 stories high. We are the tallest building in town, without any obstructions like trees or other buildings. My initial plan is
to build something similar to something from otherpower.com and put it up 20 - 30 feet in the air. Thanks for the reply, I will look at the magazine
article. If you think of anything else, give me a line. Thanks

I have looked at it. But as sspence put it it soes not have amything to do with wind. Talk to you later.
