Coil winding / Re: How to determine the lmits of a coil / magnet configuration
« Last post by brandnewb on April 07, 2024, 09:42:25 AM »Ok Sir,
Please see if I am following your lead well enough of that I need to make changes.
I have the gravity torque setup ready now. I think.

And this time I will test the failed 6 coil stacked 3 phase arrangement.
It failed because the coils moved during the curing so now there is no longer a perfect 1.25 degree of separation between each phase.
Also this test is too thick and too heavy and also just not homogeneous enough.
Nah I will do it much better next try.
{1}Also a single coil of 300 winds at 0.4mm is 92 grams net. So excluding any resin around it.{1}
(Attachment Link)Can you please elaborate a bit on what is OD and ID.
And what is it I am testing for again?
In my previous thread you mentioned we are looking for the sweet spot for how much mechanical resistance the coils can provide to the magnets to produce amperage or something to that extend.
Is this still related?
The point is to find the optimal inner and outer diameter and thickness of a coil that provides the most resistance.
The problem is, the magnet's radius is also a variable. You cant have the magnets too far apart, because when you connect all the coils together, the current is flowing through other coils which are not producing voltage.. so ideally you need 3 test coils, connected in Y, but shorted. Or perhaps better, rectify the test coils and short the rectifier.
So you want to keep your magnet and coil ratio, and magnet spacing (both are variables you can change) such that you ether get a clean sine wave, or a trapezoid, but if your magnets are too far apart, you get a sine wave ish pulse, followed by dead space, then a pulse of the opposite polarity, and this will be worse.. unless you rectify every coil separately.
I am ready finally. I can now do anything you suggest just like @joestru.
This hint is that I am ready and waiting with sensors. To measure .
just in general what I do not like is that fair interaction is not persuaded on.
