Wind Generator Using 38 volt Ametek DC Motor
homesteadworld.com Home-built, DIY wind generator using 38 volt Ametek DC motor generator. Blade speed is geared-up 2.5 times with v-belt pulleys to make the generator spin faster.

nice video.
i always like home made wind turbine 
And after all that has been said here, what the hell can you power with it? What do you use it for? I have no idea what it is capable of!
some people just lack the metal capacity to watch some thing like this and cant pice together what hes saying i give him 5 starts
awesome job!! My winter project this year during cold and snow time is going to be building a vertical axis one…. I have confidence in my carpentry skills but the wiring and motor and invertor and all that will take some learning.
Sorry for ruining your evening. Maybe you should consider getting your alternative energy advice from a professional speaker instead of an off-grid hobbyist.
“You can, uhh, see, uhhh, that, uhhh, uhh, the, uhh. It’s uhh, uhh, its… really uhhh.” (Take out the “Uhhh”s and your 4 minute 47 second video would only be 45, uhhhh, seconds long)
A very good video, but my ears hurt by the time it was done. Uhhh…
nice job.. especially your gearing system..
The battery clamps the voltage down to a reasonable level… I use the same 38 ametek same as the guy in the video but with no gearing!! I do get 60 mile an hour winds here so it`s madness,,,, get a nice 5amp to 7amp tops out of that motor….. 3amp usually on gusts….good motors..those ameteks for off the shelf generators
The charge controller takes care of that. The wattage draw creates a load that holds it back.
How do you keep the voltage from getting too high in fast wind?
nice man respect.
thats pretty good.
That seems to be the common wisdom, but the generator was turning without a load in the clip so it was over-speeding. When it runs under load vibration is not an issue.
Nice solution to the RPM mismatch issue between turbine and generator. You’ve got some serious vibration problems though. I would suggest that you drop the ABS blades and use PVC. Using 3 instead of 6 blades will also give you some more RPM (at the expense of torque). Another serious source of vibrations could be the turbulence generated due to the proximity of your tail to the roof (almost touching each other!) Make your mast a couple of metres higher and I bet you will see great improvement.
It get’s up to 12 volts pretty quickly. I don’t think that getting up to 15 to 18 charging volts is a problem.
How many volts you get on average with that thing?
good idea mate!! In scotland I actually got the ametek 38 volts to put out 6 amps at over 12 volts. It`s down to having a really good wind here..All the same I prefer solar as it`s a lot safer… Check my mad videos out lol.
To simplify construction I just ran cable from the generator down the mast. I have a plug that I can pull to unwind the twisting from time to time.
do you use brushes to take off the power onto rings on the support shaft? Otherwise if the whole thing rotates a flex will twist and eventually break.
Commercial panels are $4 to $5 per watt, but you can get it down to about $2/watt of you source your solar cells at eBay and make your own weather-tight enclosure.
really i just thought solar panels were expensive arn’t they?
While these are fun, if you’re going to be off-grid you’ll probably better off concentrating on making your own solar panels. The power from solar panels is a lot more reliable. I may do a clip on that this summer.
sweet i like what you did here im moving to a place that’s off the grid here in a month or so, so im trying to put a few of these together.
Have you tried to check the resistance of the V belt? I wonder what a gilmer or notched belt like a car cam timing belt would do as far a being easier to rotate?
Nice work!
Actually, the blades don’t stop. They only appear to stop in the clip due to the strobe effect from the camera frame speed.
