17 Responses to Home made windmill generator part 4 – winding the coil
Glad to know about the cogging but when I asked what about two magnets (one on each side) I meant in response to your previous answer. You said the height of the magnet should be no more than the magnet but what happens when there is a magnet on each side? Double or halve that height?

If you have metal inside the coil then it will cog for sure, no matter if you have magnets on just one, or on two sides.

Well, I have been told that if I use a metal core it will cog even in an axial generator but I have no idea and what if I have magnets on both sides of the coil?

The optimum size (and shape) of the coil is the size (and shape) of the Magnet. When you have a coil with many windings, then the most average winding should have the shape of the magnet, unless you use several magnets for just one coil.
The max height is the height of the Magnet if you use Magnets only. If you use Iron to channel the magnetic flux, you can increase the high somewhat.
I have no mathematic proof of that. This is just my subjective experience from my own experiments.

I have asked this question on several videos but no one replies so I hope you will but how high should my coils be or at least the max height for one? Not thickness but height (just to pre clarify as I might be using the wrong term) when on a flat surface the height is the flat bottom to the flat top.
Do you know?

Very awesome and you speak English so well and I know I would be a blithering idiot if I tried yours.

btw the coils can be larger if u use metal stator.

You made it all with the hard way.
I built my generator from old motorbike spark generator “magneto”
I unwound the thinwire coil and replaced i with stronger 1mm copper.
got output voltage at 320rpm 22v 5a and after filtering 28v
so i can charge 2 car batterys at the same time.
nourmal output power of 100w
built took only 2 days

Thank you for the c-clamp 🙂

Great job btw the blue tool is called a c-clamp in english Thanks for making this simple for us to understand 😀
what kind of magnets are those?

Because without glue it acts like a spring and will unwind itself.

Thank you for taking the time to make this video.
Why did you need superglue?
