if the magnets are interacting with that bolts, doesn't that mean a lot of the energy is being lost trying to fight the bolts and not going into the coils?
Not much. It's like a roller coaster gaining speed while it goes down and trading it off to get to the next hill. The actual loss of efficiency would be from friction and eddy currents. Since the magnetic field is mostly parallel to the bolts, the eddy currents are not going to be huge. It would make a bumpy ride though. Depending on the rest of the system there might be some harmonics that you'd want to avoid at certain rpm, just so it doesn't shake itself apart.
That's what I was thinking, the bolts might be affecting the magnetic field. Might be worth experimenting with non magnetic bolts. Also I have found common cheaper neodymium magnets do not have the north-south poles on the opposing flat faces, north-south runs laterally (ie, cut in half like a pizza, north is one half, south is the other).
Very nice. You could also add another set of coils on the other side of magnets, to get more current if coils were connected in parallel (or higher voltage if connected in series...).
@@maciejnowakprojects If you could stack discs like this: "magnets | coils | magnets" or even "magnets | coils | magnets | coils | magnets" you would get much stronger magnetic field crossing the coils... But at the same time, it would take a lot more force to rotate it. (That is with load connected, due to Lenz law).
The bolts might be affecting the magnetic field. Might be worth experimenting with non magnetic bolts. Also I have found that common cheaper button-type neodymium magnets do not have the north-south poles on the opposing flat faces, instead north-south runs laterally (ie, divided in half like a pizza, north is on one half, south is on the other).
Another great, high-quality project! Thanks for sharing it. Have you ever thought of connecting the generator (through a gear box) and rotating it by hand?
@@maciejnowakprojects It's pretty cool, but obviously your skills have really evolved since then. How much improvement would you guess your new design has?
Takie polskie imię i nazwisko. Why do you use metal cores for coils, the magnetic flux may be a little higher, but it is difficult for the generator to start and the greater the load, the harder the movement on the shaft is. I am interested in wind generators, coils with a metal core are not suitable for such work, perhaps a design can be configured for the constant gravity load of water, but for wind it is unacceptable in this form.
Excellent project! I liked the nice clean result from potting the magnets.
What a great project. Your notations make it better. I’ve always wanted to build a generator like this.
Thanks!
I still love your projects! I'm looking forward to the next one! I hope to see your creations again like the crossbows 😁💪✌️
Thanks !
Licznik zwojów na początku mi zaimponował :)
Brilliant work, Maciej! Really well done! 😃
It could probably work well even for a wind turbine!
Stay safe there with your family! 🖖😊
Thanks!

maybe aluminium bolts could be better choice

I’d say by the looks of it when he spun it that your answer is a yes.

You mean one face/side is north/south ? Like faces of a coin ?@@jumboegg5845
Very nice. You could also add another set of coils on the other side of magnets, to get more current if coils were connected in parallel (or higher voltage if connected in series...).
It's a great idea to make a generator like that using a few discs with magnets and a few sets of coils. I'll think about it

Great👍 i appreciate your knowledge and algorithms for doing them
Good job mister beautifully done
Fascinating as always.
amazing bro such an inspiration
Maybe good in combination with a water turbine? Nice build
Thanks! Unfortunately I don't have any rivers nearby. Maybe next year I'll use a similar generator to make some kind of wind turbine :)
Wow nice tools
Thank you for tutorial of making generator
Nice vid Want new powerful HHO generator ❤❤

Thanks! I once made such a generator, but from a ready-made power steering motor : th-cam.com/video/QxFk2mKBSJA/w-d-xo.html
@@maciejnowakprojects It's pretty cool, but obviously your skills have really evolved since then. How much improvement would you guess your new design has?
This two guys generator can be converted to brushless motor.
with another set of magnets mounted on the other side with opposite poles aligned would be a full axial flux generator with much mor output power.
Why not put coils on the other side too so both sides of the magnets are used?
Please, can you test put the coils in series and use only one bridge rectifier in the output to see if it is better?
Great job 👏 👍
And thank God you are not making free energy 😂
Well there is no such a thing as a free energy
@@highvoltage19 free energy doesn't exist 🙏🏻
I try to approach generators from an engineering perspective, not play with fantasy :D
@@maciejnowakprojects and I love that❤️ really 🤗
I found out when you add epoxy over the magnets, it losses some of its magnetism.
18v drill = 17v output
How is this good?

How much for one
Soooo... connect that to your steam boiler and you have a power station 🤯
Now use that generator to charge drill batteries for infinite energy glitch.
Please use a winded armchair with brush for output🤔 you know induction motor 🤔🤔
Brushed motors are worst generator
@@highvoltage19 did you try them with permanent magnet 😎👌
Only brushed motors are perfectly available for power generation 😎👌
tbh I don't get it. Just connect led bulb to drill battery? lol
Forse non ho capito io … cioè hai creato un generatore di corrente elettrica … alimentato da un motore che va a corrente elettrica ????? 🤔🤔🤔
his windmill didn't fit in the workshop
