- I bought this mini hydro generator to see how it works. Let's test it, run some numbers, then tear it down to see how it was constructed. They make 12v, 5v, 80v versions, I got the 12v.
INFO FROM SELLER =================================
Product details of Original DC 5V/12V/80V Micro Hydro Generator DC Water Flow Generator Turbine Generator Hydroelectric Tap Water Flow Hydraulic DIY
12V: DC 12V regulated output, which can power and charge 12V radios, and power LED lights.
Mechanical characteristics and operating environment:
(1) Appearance: clean surface, no rust, no scratches, firm structure.
(2) Axial clearance: 0.2-1.0mm
(3) Mechanical noise: ≤55dB
(4) Generator unit weight: about 90g
(5) Generator life: ≥3000h
(6) Output characteristics: The output voltage without a voltage regulator circuit is proportional to the water pressure
Specification:
Technical conditions:
Output peak voltage: 80V (1.2Mpa)
Output peak current: ≥220mA (12V)
Line-to-line resistance: 10.5±0.5Ω
Insulation resistance: 10MΩ (DC100 megohmmeter)
Water outlet closed peak pressure: 0.6Mpa
The opening peak pressure of the water outlet: 1.2Mpa
Start water pressure: 0.05Mpa
Terminal: 2pin
The model corresponds to the power generation output type:
0-80V: DC 0-80V output, the generator does not have a voltage regulator circuit, the peak voltage reaches 80V, it can directly charge 3-12V 10W LED lights, and can directly charge small batteries, the peak charging current is about 220mA, because when charging The generated electricity is used up in time, so the voltage will be automatically maintained at about 14V, and the appropriate voltage will be maintained so that all the generated electricity can be used to charge the small battery.
5V: DC 5V regulated output, which can charge mobile phones, and can also charge lithium batteries with charge management chips.
12V: DC 12V regulated output, which can power and charge 12V radios, and power LED lights.
Mechanical characteristics and operating environment:

Thank you

The A7 diodes are 1N4007W - 1000V @ 1A and the MCC349B are 1A Zener diodes that they are using to clamp to maximum output to 12V. This limits to efficiency and at high flow rates (>12v) will load the wheel. I suspect on the 80V version the Zeners are not fitted.
Curious? If one would modify it by changing the tiny pre rectifier wires with a heavier gauge. Ohms law would support the theory.
sir i have submersible pump working 24/7 is it enough if e put 2 of water turbines to charge battery? if it is how many hours of 12 volts battery to fully charge?
@jeromeprado4497 No, as I said in the video, this is not practical for real use, it's only good for demonstrating the principle.
Super
Very informative!
I have a question. Will this be able to trickle charge a car battery every time someone showers or use water?
Probably not any practical amount. A solar panel with a charge controller would be better.
Not in a significant way if it is installed on a typical small family home. But I guess it would be useful if it is installed on motel or hotel, especially a high rise hotel with a hundred rooms and a busy laundry service!
The main detail I would like to know is whether the magnets are neodymium or ferrite as this makes a difference in their performance
I did not cut the plastic impeller open. I'd guess from their strength they are ferrite. If you make the magnets stronger, then start up force will be greater and it will require a higher pressure to turn. Also, to make this deliver more power, it would need bigger wires in the windings and better cores.
Do you have any idea about what power scalability would be with increased waterflow
It's probably pretty linear up to a point, and I'd guess I was more than half of its max.
what type of turbine does it use?
I think it's called a reaction turbine.
Pretty cool but I am wondering about its usefulness as well. Good testing though.
I concluded it's only good for teaching and learning, but not much otherwise.
thanks for the video.
The Input hole is very small than the output hole
Where do you see that? I gave it to a teacher friend already, but the input is a bit smaller, otherwise water pressure would build up and restrict flow.
@@tsbrownie Oh I think My one is faulty now I am sure the hole keeps small intentionally
