I bought one of these and tested it. They only have 2 problems. The blades are no good and the alternator is no good. They do come with some nice stainless steel bolts though.
It must have the 6-diode bridge rectifier built in. The stator looks like a 3-phase wind, but, only two lead wires. Reading the voltage on the meter in DC suggests, the rectifier is built into the alternator. The best way to use this turbine, is with a pulse width modulator, that can load the alternator proportionate to voltage, emulating a pure resistance. The maximum current needs to be limited to 5% of the short circuit current, to allow the voltage to continually increase proportionately to rotor speed. The maximum current available is limited by the field strength of the magnets/stator impedance. The fact that it can produce high voltage at very low RPM means that the current is very limited. Connecting this straight to a battery would limit the current available, and create a minimum wind speed necessary to develop charging current. that current is greatly limited, because of magnetic field strength. A pulse width modulator can allow the voltage to rise, by reducing its duty cycle. That extra voltage times the current becomes wattage, which greatly increases amperage available to charge the battery, no matter what voltage the battery is. Since the maximum output of the alternator is the same, no matter what the battery voltage is, the wattage available from connecting the turbine direct, is exactly proportionate to battery voltage. The current (above a certain wind speed) is exactly the same. Without an electronic controller, don't look for more than~30 watts into a 12 volt battery, or 60 watts into a 24 volt battery.(roughly 1/10 its rated power!)
You have to remember to divide the wattage spec by 1000 to get actual watts. Chinese watts are much bigger than ours.
😂, ok applichero' questa formula!
I've seen the john daniels video
I'd like to remind you, to perform the test of the hoverboard wheel motor. In my opinion way better (cheaper, more powerful) DIY solution.
You will also attract more viewers to the channel. Cheers.
Hello, I remember your advice and I have already taken it into consideration .... as soon as I have the opportunity to find it, I will try it. Thank you
WAY TO THIN WIRE AND TO SMALL MAGNETS...other than that a vertical do not have enough rpm to run a pma type like this
Right what you say, generally these generators start producing above 400 rpm, a rotation speed that this type of rotor will never reach.
Thanks for the video, How many cycles for 24v, and how many amps does it give?
I will carry out all the power tests in the next few days and publish it here but I expect not good data .....
Watt geteilt durch 1.000 ist die wirkliche Leistung- ein Fehlkauf
I have seen the exact same unit from many vendors so if a person wants to get one of these they can easily find a more reputable vendor than Vevor.
Hi JustSumDad, yes there are many companies, I think all Chinese, that produce this type of generator, some work but many almost for nothing .... the number of revolutions that this type of rotor reaches is very low for many coupled generators.
@@windturbine I belive these are all produced in the same facility and Vevor just has their lable slapped on it, I got screwed over by Vevor via false advertiseing. Lost money and had no use for the product in the end. Via Aliexpress at least the buyer is covered mostly, not completely, but mostly.
All small wind turbines actually achieve much less Watt than specified. All practical tests show that small wind turbines hardly generate any electricity. And only at costs above 1$/kWh!
There is hardly any wind near the ground. And it is also very gusty, which extremely reduces the service life of the systems.
With solar systems, you can reliably generate electricity for about 8-12 cents/kWh over a period of 25 years!
Hello, I wanted to ask you a question, in many videos I see that they also have to connect a controller, while only two wires come out of my motor as they say that this controller is already built-in. My question is... while it produces the wat, can I connect it directly to the heater or do I have to put a charge regulator. Thank you
Ciao Maria, hai questo tipo di generatore con uscita a 2 fili?
@@windturbine Si esattamente.
Great video, If you would explain what's going on here instead of that horrible music.
Has it a inbuilt controller? What happens in stormy weather?
Hi, it has DC output without built-in controller, it won't produce high power even in stormy weather! 🤷♂️
But the text says so and highend microprocessor..i have one here in a box but this will be dangerous to install with my solar panel...ffs
@@kristianlarka802 It is declared like this but it is not so ... when empty it reaches 160 Volts!
Any idea how to get it safe? Or just throw it away? 😅
@@kristianlarka802 Trash the fastest solution!
Spinning it with no load is a waste of time. Test it with a dump load. I bet it cannot produce more than 200W.
Hi Tubeophiliac, in another video I tested the turbine with load. Power less than 10 watts!
Se puede conectar directamente a batería?¿
Hola Vicente, no este modelo no tiene controlador de carga.
Hoped to learn something but that muzak made me go elsewhere. Good luck.
it's 3 phase?
The motor is a three-phase and has a small rectifier diode bridge inside so the output is in dc ...... the performances you can see from the video .....
@@windturbine you mean at minute 3:07 that small white with red strips tape it's covering a diod to retify the 3 phase in to single phase 12v dc?
@@davidjcunha yes!
@@windturbine Tks a lot. keep up.
Dove può comprare ?
Ciao, ci sono tantissimi produttori di questo generatore e viene venduto in molte piattaforme. Per la sua struttura ti sconsiglio l'acquisto, molto meglio una classica turbina orizzontale, la forma del rotore non consente di raggiungere velocità di rotazione giuste per produrre corrente.
@@windturbine qual vc recomenda para 24v seria eólico vertical, que estou querendo comprar para carregar baterias de 160 ah ligadas em série no off grid, qual o link de compra vc indicaria.obrigado.
@@marcosantoniochiavegatti7951 Hola, recomiendo comprar turbinas horizontales de este tamaño, con verticales de este tipo el rendimiento es casi nada!

Hi Imran, tell me what I have to answer?
Now way it can produce 600 watts (50amps). I doubt if it would produce 5 amps (60 watts) . The wire is too fine.
It probably will give you 12 volts, but that is just to fool you into thinking you might have something. Total Chinese junk.
Yes, the situation hasn't changed, you don't get to produce 10 watts at 300 RPM, a rotation speed that this rotor will never do!
