Hi, thanks for replying. I know that the coils of motorcycle generator can't produce 220v I can made other coils with high value, but I'm talking about the size of the magnet if it can produce 220v with the right coils?.I don't think so. Motorcycle magneto coils only produce about 20 volts
Specifically, when the number of turns of the coil increases, the electromotive force value of the electromagnetic induction phenomenon will also increase. Therefore, the more turns of the coil, the higher the voltage induced by it, in theoryHi, thanks for replying. I know that the coils of motorcycle generator can't produce 220v I can made other coils with high value, but I'm talking about the size of the magnet if it can produce 220v with the right coils?.
Hi Brian nice talking to you again.More turns on the coil = more voltage.
However, it doesn't necessarily mean more power. You might get a higher voltage but lower current capability, there are many variables so an exact figure isn't easy to quote. For the same amount of mechanical (rotational) input you will probably get slightly less power out with more turns because of other losses but a good estimate will be the same number of Watts as the original coil produced. Add together the headlamp and tail lamp power of the motorcycle to get the original load it was designed for.

I understood, I'm working to make 10 coils connected together to make sure of getting high voltage and power. Thanks again.Specifically, when the number of turns of the coil increases, the electromotive force value of the electromagnetic induction phenomenon will also increase.

Hi Klaus, so it's about the all three factors, I understand from you that to make sure of getting high voltage and power I must increase the all factors as much possible. I'm working now on the coils's core and as I was worried about ending with low voltage and power after a lot of work so I'm making a core of 10 coils connected togheter, do you think that would be enough?.Hi.
Output voltage becomes increased by:
* increasing winding count
* increasing magnetic field
* increasing RPM

Hi Brian nice to meet you, the coils are stationary, the magnets rotates, you can see in the second picture that black piece of iron which is in circle form where the magnets are installed, that it's rotate, the magnets rotate.Sorry if I'm going blind but please explain which part is stationary and which part rotates. It looks from the photographs as though the magnets are bonded to the coils.
What are the wires looped around the magnets?

fan which it has made to used it and installed in ceilings of rooms
Hello, I appreciate your help, you are right, this fun rotates slowly.I read that ceiling fans are designed to be inefficient so they turn slowly (as compared to AC motors which are made to spin rapidly under load).
I think it has to do with the arrangement of windings for ceiling fans. To some degree they oppose each other, thus using inductive impedance and not resistive impedance.
building generators is about 150 years old. It follows simple rules of physics. All well known, no secrets. No need to guess.One knows how to orient the magnets and the coils. One can calculate the torque, the voltage, the current...I didn't have any idea about the arrangement of windings in these kind of fun until you explain it perfectly,
Yes, after I've read what Brad said explaining the way these coils made I totally understand now, I didn't have any idea of this fun arrangement windings so this is a new important information I learned.I agree with Brad on this, the design is not intended to produce high power. The resistance of the wire alone will limit the output power.
Another question regarding the magnets (from magnetrons?) are they all aligned the same way or do they alternate? Electromagnetics are not my field of expertise but I wonder if the power you are generating is just from the rise and fall of field due to alignment with the magnet core or whether you are seeing a complete field reversal.
I'm not happy about the magnets being mounted on wires either, it looks to much like shorted turns in the field for my liking. A plastic cord might be a better idea.

Hi Klaus,Hi
building generators is about 150 years old. It follows simple rules of physics. All well known, no secrets. No need to guess.One knows how to orient the magnets and the coils. One can calculate the torque, the voltage, the current...
My way is: learning the theory, deciding what to build, do the math, do the drawings..... Straight forward.
I personally don´t like the "trial and fail" methods, because they take much longer and give only mediocre results - if ever.
As said - just my way.
You are free to go your own way.

yes I agree, the IC is everything in now days circuits they also play a huge role in reducing devices's body, like in drone I was talking about the remote will be like the computer's keyboardHi,
I guess one of the most challenging parts for a complete drone design is to control 3D movement, rotation and stand still in the air. Without ICs .. not my way. I think ICs make it more easy, reliable, precise and still faster to build.
And for a drone you need batteries. If you control the motors analog style then the driver will waste a lot of energy, generating heat and draining out the battery too fast.
There should be plenty of documents in the internet on how to build a properly working drone.
But if you like the challenge - I won´t stop you in this.

I don't think that the 3D movement is much challenging, at least according to my imagination, I may be completely wrong.Hi,
