James You got what you paid for. I bought a 2kw x 120vdc Yenzhou Shenzhou in 2008 and it is still working fine. I fitted new bearings before the old one gave out because s friend told mr that most Chinese bearings are not good. I lowered it during the last load of storms which was a very sensible thing to do. I paid £850 for it. It was a bargain .
I was lucky, I ordered twice, both times they said we are out of stock, please cancel order. Now I am building my own alternator from used hub motor stator and 30 magnets (repeat pattern is 9 slots per 10 poles) sized 10*40*3 mm may be thicker than 3 mm in the future
Good honest review I have the same problem. A glorified toy total rip-off good on you Jameshow many people have waisted money on these I have .when I can’t get solar power I hook up battery charger which is more effective than this rubbish. Very disappointing in the whole product . Claimed to be 500 watts lucky to make 1/2 a watt even in gale force winds
These are kind of toys. Electric engineer told me that if u wan't 24 volts and 250 watts u have to 2 meters long blades and mechanical brake to it when it get too windy. He had one made centrifugal adjustment for blades angle of attack. He calculated blade and wind speed and when wind got too high the blades angle of attack changed according to that with centrifugal force And there were a centrifucal brake too, all made from car brake waste parts.
Hi James I purchased a 300 watt turbine off alliexpress from Green E Solutions after watching a review from John Daniel I have not been able to get any power out of it emailed and sent video to seller they didn't want to know
Just load tested one here with an electronic load tester, good metering, controlled input speed.... bla bla.... ran it as high as I could spin it before the controllers brake kicked in (~800rpm). Set the current limit between 8A and 2A with about 0.5A steps, and had to drop it down to about 1.8A before I could get it to around 13V (ie, enough to charge a battery...barely). But no matter what, the math always worked out to about 35-40W. What a joke.
IMO an out of balance rotor is the biggest issue I saw (alongside the rubbed wire coming a close 2nd). That rotor spinning in a good gust at 1,000 rpm is going to shake everything apart and seriously break things.....
Forget 400 watts. You're lucky, to get 40 watts out of it. A turbine generator like that would be a better match with a 3 blade rotor with a shallower pitch, so it can run at higher speed, with less torque. You can increase power by allowing a higher voltage, at that highly limited current. A pulse width modulator can be used, to turn the high voltage low current into a voltage suitable for your battery, at a much higher current, than is produced by that turbine. The problem with that 5 blade rotor is, it can never achieve the RPM, and it produces MUCH more torque, than those tiny magnets can ever hope to use.
I agree total rubbish very disappointing. I bought a small motor and generator which I can generate 20amps have to use speed controller to slow it down.
No matter how the stator is wound, the maximum torque is limited by the field strength of the magnets. The magnets on that rotor can never hope to utilize the torque available from that 5 blade rotor. To get anything out of that turbine, a 3 blade rotor with a shallow pitch would be better, because it would spin fast, but with low enough torque, to actually get some power out of those tiny magnets.
Hi it was just a generic 400w turbine. It's the same as all the other models ranging right up to 9000w. They are all junk. If your concidering one go for a ista breeze
Judging by the size of it, it won't generate 100 watts. Electric motors, generators, welding machine, power supply with transformers, everything that should have copper winding but it's made in china, expect to have aluminum winding instead of copper.
This is not the problem of the factory itself, but the trader chooses to let the factory use such a bad thing, just to save costs. Not willing to spend money, but also want to earn more! I am a supplier of wind power, and I am very aware of the routines of Chinese traders. Especially on e-commerce sites. More false marks.
very true, if your buying a good quantity direct from the factory you can dictate the acceptable quality standards and components used. in most cases what is available on ebay and aliexpress is generally the bottom end
This is a Chinese failure Don't pay more than $80 As it is, it cannot produce more than 6w I will buy the Chinese wind turbine I will make a special device that will fix the generator
Your machine is really bad. The thickness of my iron core and magnet is 12.5mm. The number of laminated iron cores is more than yours. The diameter of copper wire is 0.7mm. It is sold as 100w machine in amazon JAPAN.

never truer words spoken, you get what you pay for
@@jamesbrokentech Annex: You get what you pay for, and not one bit more!
If you knew who built that you would say these kids were geniuses

Do you have videos of progress?
The coil is made from aluminium- no chance to solder them - I did try to change parallel to series to make a bit higher voltage
You should look at the wiring soldering inside the tape as well.
Good video. Thanks.
Anything under 500w is really a 100w max, I wish I would of seen this video before I bought this junk

they know its junk
Good finishing,,,at short time 👍,,,,
Thanks mate..
Good honest review I have the same problem. A glorified toy total rip-off good on you james
1:19 - it has 12 poles - like standard car alternator (6N+6S magnets)
Just load tested one here with an electronic load tester, good metering, controlled input speed.... bla bla.... ran it as high as I could spin it before the controllers brake kicked in (~800rpm). Set the current limit between 8A and 2A with about 0.5A steps, and had to drop it down to about 1.8A before I could get it to around 13V (ie, enough to charge a battery...barely).

5000W in china = 200W here
My 400 watt three blade turbine made zero electricity and the whole blade assembly blew off this evening!
IMO an out of balance rotor is the biggest issue I saw (alongside the rubbed wire coming a close 2nd). That rotor spinning in a good gust at 1,000 rpm is going to shake everything apart and seriously break things.....

Thanks, I have the same windmill and I wasn't impressed with the internal component either...
I agree total rubbish very disappointing. I bought a small motor and generator which I can generate 20amps have to use speed controller to slow it down.
I get more power from my battery charger. When there’s no solar working I use a battery charger to supplement power.
2:32 did you check coil wire - it can be aluminum with red lacker coating
You are right
Some time they use iron wires too,,it gets rusted within few months 😂😂
No lo puedo creer
James what make is it? Vevor??
So when buying an alternator like that how do you know which ones are junk and which ones are not?
Hard to say with the Chinese ones. It's pretty much luck of the draw
ممتاز
Mine work somehow at the beginning but something happend. I measure 50 volts ac when it was new and after 4 years 9 volts (24volt system)
How much turns which wire is used no . Gauge
No matter how the stator is wound, the maximum torque is limited by the field strength of the magnets.

I wish I knew about this junk before I wasted money on it .
This works at 180km/h wind. 😅
mine isn't fat either but it broke the coil which gives a reason why it is
Hi James, What model from aliexpress is this one? Thanks
Hi it was just a generic 400w turbine. It's the same as all the other models ranging right up to 9000w. They are all junk. If your concidering one go for a ista breeze
Can you rebuild this? To make more power?
That would be a waste of time.
It may be easier to fit new motor inside and get rid of that stator crap.
I would like to see someone do that.
Got one like this , turns for a few seconds then stops can anybody help
just cut your losses and toss it out. they are a complete waste of time
Its so junkie hes pulling it apart in the garden 😂
they have done that type of work for years thats why they are like this today
املك نفس هذه المرحة انها عباره عن خرده لافائدة منها محرك السكوتر ينتج افضل منها
It's not safe to generate power it might short out windings or a fire
There is a regulator before battery too so I don't think so.
There is no such thing as a cheap generator none of them will give you payback ever. Stay away from this tech.
Its a toys for the big boys
It happened to me, I bought chinesse turbine but it's fake, it can not reach 400 watts at 13 volts
400 Watts in a year on top of a mountain
Judging by the size of it, it won't generate 100 watts.
Electric motors, generators, welding machine, power supply with transformers, everything that should have copper winding but it's made in china, expect to have aluminum winding instead of copper.
You get iron wires in many chinese appliances 😂😂
Factory didn't a good job on that i would not buy that and buy a good one
Wich $ you paid for ?
80 pound is like 200 dollars?!
I got one of this turbines... it does not work!!! No charging at all...Do not bye..

Not all are chinese are bad, but expect to spend €170+ for a reasonable 300w/400w. This one is like a 50w 🤦🏻♂️
correct, there are certainly good turbines available from china and probably from the same factory
uhh. All chinese crap is Bad. If you ever bought something that wasn't. It wasn't made in china.
Long live made China
dam thats just junk sorry for you mte
If it’s was spinning 2000rpm yes
your been scammed. that is a 100 watt unit.
🤣🤣🤣....!...mmm
Most a Chinese motors is not cooper is 80% aluminium and 20%cooper easy burning most better is a electric motors made in usa
to be honest i thought the windings felt a bit light. could well have been copper coated aluminium
That's the worst one I've seen so far.
This is a Chinese failure
Don't pay more than $80
As it is, it cannot produce more than 6w
I will buy the Chinese wind turbine
I will make a special device that will fix the generator
Your machine is really bad.
The thickness of my iron core and magnet is 12.5mm.
