- Showing parts and pieces on how to redo your small wind turbine (applies to S2, S3, and M3 Chinese turbines) to actually produce the dedicated power.
A live test will be followed in the next videos. For now, only the parts and what to change.
Additionally here are two videos about the upgraded generator itself:
1. here are some measurements: • Непоганий китайський г...
2. here is the side by side comparison of the opened original one and the changed one: • Наочно добрий і не дуж...
Sorry, but those vids are in ukrainian, but you will get everything just from the looks. The difference is massive.

I worked at the company that originally designed these more than twenty years ago, "Southwest Windpower". The original product was called the Air. It had a much bigger rotor and stator (as it sold for much more than $100), and in high speed winds could produce well over 2KW when the regulation was disabled. The problem with doing that regularly was heat. But we never put bigger blades on them, because they were designed to survive extreme weather without any furling. One customer had deployed one of these at the south pole, and left it at a weather station over the winter. When they returned, the weather station had recorded peak wind gusts of 130 MPH, but the turbine was still operational. The original Air had an integrated charger, and could be purchased in a 12v, 24v or 48v configuration.
that's actually great.
in order to reduce heat you should solder all the joints way more then they normally do at the factory, and likely apply the special lacquer for the coils. these will be also the steps for me to ensure this tiny thing works a lot longer
We had original Air marine, body corroded in 6 months, regulating in nacelle then running DC over a distance is stupid, never got any usable power, found plans online to modify turbine by removing said controller and running 3 phase AC into rectifier. So much more power.
@@jonathanpurves5066 it is already 3-phase AC wind turbine, so all great here. you are rectifying to DC only on the controller side.
so far, I have it almost a year - no corrosion. Guess why? It has aluminum body. Same for the generator outer shells - they are aluminum.
Chinese isn't that bad, tbh.
Esos si eran buenos aerogeneradores
One more thing. You, Me and others love how it starts turning with very low wind. Old Chinese Trick. Little to no grease in the bearings. Put in good bearings and see when it starts turning. Don't worry, When the wind is good enough to make power, it will turn.
mounting height + clean wind is the most important.
also the blades lifting angle is what matters. in the new video (with the 3-blader and 5-blader wheels thumbnail) you will clearly see the difference between the blades and what makes the low-wind start actually happen.
If the generator is under designed , putting more blades may actually hinder it even more because the more blades will probably have lower rpm and will be more difficult for the generator even more.
yes, true, I ended with going 1.65 m 3-blader, instead of 1.3m 5-blader.
that one looks now like this: czcams.com/video/z1OqDNcNeZ4/video.html
@@ModernUkrainianHomestead Looks Awesome good luck !
Perfekt i was just looking for which one will fit to my vivor 400w :) newer get more then 20wats :) super thank you, I got already better blades so just to order new generator
you are welcome.
I eventually ended up with fully rebuilding it, here is the result: czcams.com/video/z1OqDNcNeZ4/video.html
since I found out during the tests, that 1.65m blades are the best for this generator.
had just mounted it today, so quite soon will see how it behaves on the wind.
and that S3 body is waiting for a new gen now again, slightly smaller one, as that one appeared too big for it ))
Can't wait to see how the upgraded new gen head does.
there is the new video about it on the channel. I haven't probably filmed the top output so far, but it was giving me 200 watts peak already, and the winds are not crazy.
I just ordered another set for a 36v 450 -watt schooler wheel wind turbine I'm working on.
My 500-watt China does make some power geared 1.4 to 1. Had some wind above 8 mph in a storm and got some power last night. My turbines would do good in a windy area. I used 3 bigger blades instead of the 5 blades that came with it.
how exactly did you gear it?
I made a front plate fitted the holes for the shaft and bolts. Plate goes about 1/2'' above the top of the gen. Welded another plate flat on top. Added some side support on each side. Medal is 1/8'' I used 2 pillow block bearings with a 5/8 shaft. Old 10 speed bike gears and chain.
Be nice if you would do a video showing the inside of the new gen.
I also added a much bigger tail so it will turn into the wind and is ready to start up when the wind is good. Stops a lot of wabble and lets it start faster.
A link to the longer bolts would be nice. Can't find them here in the USA. I may do this.
I actually opened it, and showed all ins and out on details in my ukrainian channel.
will show you two vids about it:
here are some measurements: czcams.com/users/shortsvJNRBnkJ8Go
here is the side by side comparison of the opened original one and the changed one: czcams.com/users/shortsOMz419FyKBg
sorry, but those vids are in ukrainian, but you will get everything from the looks. the difference is massive.
about bolts - it was supereasy to get them locally on my end... I paid like $1.5 for 4 inbus 90mm long bolts fitting the gen. actually got them in the nearest huge construction goods supermarket ))
Thanks, I checked it out.
How do you connect the coil? Working on one to demonstrate with students at my school
it's a factory made generator, so I did not do anything with the coils, just reconnected the three phase gen-output to the coal-brushes current transferring module.
however, in case you are interested in its inner structure, here are some of the details:
12 magnets on the rotor. then 39 gaps for the coils on the stator, of which 3 are left empty, and others are divided into sections of 12. coils are put into "from 1-st to 4-th gap". in the end all are combined into a classic star connection. however, since they do it at the factory - the single-phase-coil is uninterrupted, I have no idea how they manage to put it inside the gaps in the end, but that's how they produce it. looks like the generator has 12 poles only as well, however, it's mainly because of its relatively small size. in bigger size generators they normally use the 2/3 ratio of "magnet rows" / "coil-poles".
Thanks for the channel and info. I think you'd do better with a 3 blade believe it or not. 5 blade starts sooner but you lose energy when running. lots of vids...
Yes, that's true. I ended up with 3-blades but bigger diameter for this gen.
How is the upgrade working?
Still waiting for my batteries to arrive. After I put it on 24v battery setup -there will be an update.
On 12v it will work if put directly through the rectifier on the batt, but I won't do it this way.
Does 5 blade have a lower start up wind speed?
in the same shape of blades and same size of blades conditions - yes, 5-blader will start at lower wind speeds than 3-blader.
however, for this exact generator it appeared to be that 1.7m 3-blader hub (with a proper low-start bend on the blades) works so much better than this 1.3m 5-blader hub.
can you give link to that new nbigge generator
sure, it's in the description just below the video.
but here you go as well: s.click.aliexpress.com/e/_DDPnQ9B
25 mm of steel inside, pretty good one for the size. don't count for 1000 watts though, some 400-500 might be well real.
Anyone who's watched Only Fools and Horses will remember Trigger's broom.
haha. exactly. that's what the modification is all about - changing parts and pieces my friend, isn't it?
in my cases - parts that FIT PERFECTLY, like as if they were designed for it.
good question to the manufacturer remains though - why not making the wind turbine in already improved state from the very beginning? I don't have the answer for it.
@@ModernUkrainianHomestead They say two wrongs doesn't make a right but if you could reverse mount the blades (1. Mount it wrong, 2. Spin it in reverse), I think you may squeeze a few extra watts out of it. The extra watts could come from the expense of steering - instead of wasting energy trying to steer into the wind, it could just spend it on generating power. You may have to clip the tail off.
You could also drill out most of the rotor to cut down the weight. This would squeeze a few extra watts out of it too.
actually the opposite it true about the weight - more weight will add more moment of inertia, which will make it spin more smoothly and will result in better output.
also, it's impossible to mount the blades reversed - since they have specific mounting places with the predefined mom/dad items to fit with the hub if you know what I mean...
I made a small wind turbine but it produced 10 volt with 3000 rpms on rotor. What can i do to produce more volts. The copper coils is very thin copper wire.
The rotor is 16 mm thick and i used niodemium magnets. Very strong ones
Let me guess, you have got coils less of same amount as the magnets number?
Be sure to use many-poles generator to get better voltage output (the ratio should at least be 3/2 for "coil poles"/"magnets", but you can go with bigger one for coils as well), also combine it always into the classic "star" three phase connection in the end.
@@ModernUkrainianHomestead i got less magnets then coils. So i need to use more magnets.
@@ModernUkrainianHomestead more poles to get more volts
How is the gen upgrade working?
Getting my batteries today finally, so will mount it in 24v system.
Also 5-blades have the slow start (for this new gen), at about 4m/s, which means I am trying the new 3-blade setup soon (1.7m wheel), as it will have more torque for a better rotation start.
NOT SAYING to do it, but I cut 6'' off the 5 blades and spins lot faster and is lot less noise. Still starts in low wind but just takes a little more to move them.
How to upgrade your house. Demolition entire house and build new house. Thars whar we do with turbine buy new turbine this is nog ant upgrade
no, this is not true. since I keep a lot, I keep the body and the looks, and change only what is easily changeable and goes to the exact same mounting places: the gen and the windwheel.
the main upgrade is a gen, and since my gen appears to be a little bit too strong for the default windwheel - I had to get a new windwheel with way more torque. if I would have gone with a little bit less powerful gen - the same windwheel could've been left.
What's the fun of just buying one that works?
@@basilkey2949
Absolutely! No fun - if it works it just works and its boring...
I got my tiny S3 wind turbine just as a working model of HAWT. It showed me that it's possible to get something out of the horizontal turbines, and it's not possible to get anything from the vertical ones (I've got one tiny VAWT as well).
Then I scaled up with the horizontal, and got a bigger one.
However, I asked myself a question if this tiny S3 beast can be improved somehow, since the manufacturer definitely missed a lot of stuff that can be better.
@@ModernUkrainianHomestead I will tell you about mine. 5 blades 500-watt China junk. Looks a lot like what you have. I did not get the start charging amps. It did put out 8 maps at 800 rpm with a drill. STORM WIND...I made a mount with bearings and bicycle chain and sprockets. 2:1 with 3 bigger blades. I have seen a little power from it this way. I'm not in a good wind spot. Love this stuff.
