Let me understand correctly.
Given the mouth of the carcass.
You did upside down in each slot with a single wire to do only back and forth.
Like thread with a needle to fix a button on a fabric.
No possibility to mount the coils in advance.

Bravo
You must have had a great time of loneliness

EDIT: something else I noticed.
The stator in place in the black head towards the hub has a play of position of approximately 3 to 4mm. It is centered by 3 half-moon plastic nipples which puff up very quickly if the stator is slid inside.
This partly explains the fact that in place the rotor comes to touch an edge. The rotor pulls the stator from one edge in the interval of this little game.

The stator in place in the white plastic chassis is perfectly centered without play this time, there are 6 square nipples with the possibility of making 1/3 of a turn on the coil on each side. 3 point fixing.

The ideal way to reassemble is to fix the stator to the centered white chassis, to insert the rotor in the black part (in its bearing). And to bring the two together.
Problem: at the last moment the rotor will attract and remove the stator from its housing. So you would have to stick the stator to the glue gun for example.
Or mount everything in the black head and add 3 identical shims to center the stator because the 3 half-centering moons are really shabby.

Ay,
I tested, I don't have the exact values ​​but a priori I have 20 VDC around 222 rpm.
I tried the machine with the original blades. It turns really not even with the winds of 15 -20 m / s !!!
Test not to do especially. I was holding the machine in my hand.
Then I put the rest of the Missouri hub. Even Completely unbalanced it turns but danger.
Then I put three missouri blades on the original hub of the Ista. It turns but danger. Manip not to do!

FYI, all the big wind turbines in my sector are in safety mode. None turns. Beautiful breeze from the past today. You would have thought you were in the Mediterranean or on Mont Aigoual.

Besides, I have the impression that a gondola on the park has made a small tour 80 meters lower !!!

slut,

In a pretty job :) and 220rpm for 20 vdc it's good, you tried with a load and measured the amperage;) ???

in two is that the rotor turns easily by hand?

At 20 m / s of wind even with a short set of blades this should start at least ????

I tried charging on a GTI 10.8 V -28 V.
I haven't done a measurement yet.
You have to do it slowly because when the GTI grips, the torque increases suddenly and then you have to accelerate slowly because if it doesn't, it goes into Dump Load mode !!!

Speaking of GTI, I have my GTI who passed away yesterday !!!
Pffff!
I started diagnosed. A wire of the tranfo unsoldered !!! But I have a component which seems to me to have smoked. I don't know those. I think it's a condo.

Also look at the CIs.

Very interesting :

The rotor turns easily by hand directly on the axis.

Your unknown brown component is a fuse.

The reference of scratched CIs is a great classic! (and not only on Chinese equipment)

Thanks Forhorse. Well, he is dead.

For the measurements I obtained 1.5 A connected on a GTI which does not manage to stabilize on a voltage which varies between 12 and 28 VDC !!!

I will try to connect it to a bulb !!!

Now with a tension 4 times higher, the GTI does not support a small speeding with too high tension.

The GTI is to be redesigned !!!
to accept a much greater range of input voltages without dying and regulate the current at maximum power more gently, without picking up !!

It's just a microprocessor program

Bein to compare, was it not necessary to have the correct measurements BEFORE the breakdown?

And before changing the program (gloups!) If the condo went down, there was a cause elsewhere upstream. If it re-slams in overload but everything else works well in normal situation, shouldn't we try to put a stronger condo and ... a diode to avoid a too rapid discharge, right?

I had found quite a few pieces of plans and program on the GTI. But nothing complete and especially in French.
Do you know good addresses?
In fact, there is Windmaster and swea.

For obamot, he died the GTI. (it was the one of my solar panels). sniff no luck !!!

Ruthenian. Don't take it bad, but ...
You talk about the GTI of your solar panels.
But you're talking about a 10.8v 28v. It's not solar that ....

Your original ista blades turn no better, because the magnets stick the caracasse of the same winding. Rewinding does not change anything: to start the rotation.
