30KW Chinese PMG. Load test with flywheel
Просмотров 4,1 тыс.3 месяца назад
In this video I add a flywheel to the PMG and add a resistive load so that I can run some actual load test to see the power output of the PMG and to see the output voltages under various spin velocities under load. #diy #diycrafts #diyideas #africa #kenya #renewableenergy #pmg #chinese
300Kg PMG Cement Flywheel Mounting Build and First Spin Test
Просмотров 6 тыс.4 месяца назад
Design and build of a stand for a steel reinforced concrete flywheel for use with a PMG. I had to create this flywheel in order to achieve the required amount of torque and momentum required to test the full capacity of the 30KW Chinese PMG. I'm planning to couple. The flywheel weighs around 300kgs. #microhydro #homemade #flywheel #pmg #welding #diy #tech #africa #renewableenergy
Steel Reinforced Cement Flywheel for PMG (Permanent Magnet Generator)
Просмотров 7924 месяца назад
In this video I take you through the process of how I made a steel reinforced cement flywheel for use with a PMG. This was necessary in order to reduce the speed of the PMG to the rated 200 - 300 RPM and to also provide a smoother output voltage and frequency since I want to put the generator under some heavy abrupt loads such as welding and motor startups. #diy #pmg #generator #renewableenergy...

Permanent Magnet Generator (PMG) Unboxing - Chinese - 30KW - Aliexpress
Просмотров 7 тыс.6 месяцев назад
Unboxing of a Chinese 30KW PMG (Permanent Magnet Generator) that I bought off Aliexpress. Rated at 30KW Initial assessment of expected output before actual testing.
I bought the three-phase generator, but I have a problem that we can't start it, the generator has three output phases but not the neutral phase, how do I install the neutral phase in the 10 kw generator with 300 rpm can someone help me
This PMG Alternator is built for low rpm from 300 to 500rpm with high torque of 40hp power to achieve the 30kva
Hello sir pls can I have your whatsapp contact
а не фейк как многие любят их показать
молодец вот это я понимаю действительно действующий аппарат электричество 👍🔥🔥🔥
Are these AC really? Or DC I just bought a 48v 5,000w Haventvtested it yet
@@cudasai They are 3 phase AC. You can watch my other videos where I test mine. I'm not sure about the internals for the 48v one so it's best to test it out for yourself. But mine was nowhere near the specified wattage. I ended up modifying a motor to pmg to get the type of power output I was looking for.
pls sir am moses from nigeria can i have your whatsapp line pls...
How on earth could this one be a 30 kW why is the output wire looks less than 8 gauge at list ? I’m totally confused.,
Felicitari pentru ce faci🎉
Muito bom parabéns
I am looking into generators. Does your generator run on gas?
The engine is designed to run on petrol but I run it on gas.
Good naic🖒
Hi , I am planning to use same 10kw PMG and govern it with. 1hp 900RPM AC motor , I am looking for 220v output but the pMG manual shows 500RPM will it burn my appliances?
Hello sir Can you send me your email I have a question about PMG?
You need at least 3hp gasoline or diesel engine to drive a 1hp electric generator at 746 watts. There is no way on earth that the tiny gas motor you have will run a true 30kw generator..please be careful purchasing chinese generators!
Hello Sir Can you send me link of Aliexpress supplier How much cost 30kw PMG
😂
Bro what happens if to connect all this wire between to make one phase, connect like extension of battery see what happens
The only way to connect them together is by rectifying them to DC first. Otherwise you will just be shorting the windings or the phases will cancel each other out and you get no usable output. If you rectify, then you will have to invert the DC if you want ac output. That's too many steps each with it's losses
Dear Sir, Thanks for posting PMG new product Can you tell me the price and capacity in kw
Great work. Much respect 🙏
Thanks for share us new Source of energy. how much cost of 30kw PMG? Can i drive by electric motor using reducer gearbox?
Can someone say how much amps does this generator produce?
I would recommend getting more than 1 amp given the winding's resistance is 59 ohms. You won't get more than 300 watts from this directly unless you do some work arounds like in this video ruclips.net/video/ndB2EjCFUrI/видео.htmlsi=vA-nrQK9RQPlL4ab
Another thing wanting to know if we only put north side would current flow?
Thanks for video What diameter of wire should be windings and turns or length of wire?
30kw ,240v , 125A ,40.2hp....how much was it
Windings data btaoge ji
Thank very much for the illustration pls can you tell the thickness size of the magnet
what's the total kva you can get from this 10kva Chinese pmg @ 500rpm please ?
Hey, that generator cannot generate 30kW. Not even 2kW. A guy used the same generator for a watewheel and the generator failed to deliver 2kW. 1st video of the series (of 5): ruclips.net/video/7l5xxIGiW7o/видео.html
It can generate some more but not at the rated RPM ruclips.net/video/ndB2EjCFUrI/видео.htmlsi=w2HNrSuUbG9W-Sl_
@@diytech4522 Yes, it can but a very high cost (melting/burning the generator). Going back to the serie of videos I pointed to you, in the 3rd video (ruclips.net/video/DInwut0DzTQ/видео.html) you can see that he's getting about 1.2kW at a BIG flowrate (about 600 RPM). Of course, the generator will melt at that speed. He decreased the flowrate of the wheel, so he got about 750W and the temp was almost 80ºC at 500 RPM. That's not good at all. The generator it's rated for 2kW but has trouble generating 750W. So, not a good generator...
@@mcksysar8620I'm not saying it's a good generator. Its a bad one and doesn't generate near what is specified for at the rated RPM because of the bad design especially around the winding's size. But with the tweak where I used transformers you can get a sizeable amount of output without overheating. As long as the current draw doesn't exceed 1 amp the IIR losses will be fathomable. He was drawing a lot of current from it causing it to overheat. But overall, a bad generator for the ratings they have specified. Nowhere near it. Not to mention the lack of active cooling among other things.
Study ohms law..volts times current equal watts. Sorry buddy this generator will never do what your after..best advice is to get your hands on a 3 phase smart drive washing machine motor for your hydro electric project..they are abundant and affordable and easy to rewire if you choose to run it at higher or lower speeds and voltages
I also had a project in mind of executing a silimar project at river Gura the project ìs still in mind despite having problems raising funds for the project probably the day will come .Otherwise you're doing great work atleast for you its work on progress 👍
A battery system is the best in this case because of the different rise in water during different seasons
You lack the requisite knowledge of flywheel , what is the moment of inertia of the flywheel,those step grooves you made is not needed
If the windings had been varnished which is normal practice the overall resistance of the windings would be better, also the wires would not have moved. The laminated iron helps prevent hysteresis and similar losses
2000 RPM is not much for an small electric machine. What did you expect to see?
@@friedrich_k It was more about the winding's insulation being able to handle the high voltages at the high rpms. It actually wasn't able to maintain the high voltages at 3000 rpm and arcs formed and shorted the winding.
not sure you know what your talking about but good on ya for making a you tube video
Hie thanks for your great work, l need the use of these transformer instead of using an invetor What is your advice on buying a 48v wind generator compared to 220v . May God bless your effort .
I already bought. And this is what I have, I want to use it without the need to charge batteries, do you have an idea?
You need reactifire single fase or 3 fase If connet direct generator must produce three times the amount watts needed by your component
I think a 48v ones might be better suited for running at higher rpms. But remember that the frequency is higher than normal for normal appliances and might not be suitable for direct use. I had to wire the input inductance of the two transformers in series to achieve a lessor inductance to match the higher input frequencies otherwise there would be a lot of Eddy current losses from a single transformer designed for 50hz ac.
Thanks for your efforts, in making this video, to show what is inside these PMG's.
Thanks for watching!
Mam turbinę wiatrową SM 6 z takim samym generatorem . Uzwojenie jest połączone w gwiazdę ale 2 faza jest odwrócona .Czy to normalne w chińskich prądnicach ?
Please count the number of copper coils. I want to know about poles of winding.
looks like 500W generator
So can use for 1.5HP or 2HP air-conditioning with 30KW PMG?
Good 👍 work
Please explore this pmg every part also mention the dimensions for each and everything because we are going to make it at home so please explain every part with complete details. Thanks alot.

30kw you would not be able to carry it the most power that might produce 1.5 kw
its 3kw not 30kw
Even less than 3kw.You are smart.
About 300watt
You cant trust chinese sellers at all..they exaggerate the power output sometimes 100 percent or more..buyers be ware
30 kw 😂😂😂😂😂😂
What is the diameter of enamel copper wire?
At most 0.5mm.
Go ahead
Chinese first made this too much higher rate selling now the price down he selling maybe this is not working
