Glad you are making progress. I suspect your alternator is still rather fast vor a VAWT but it might be worth waiting for a bit more wind.
With the gap as small as you can get it, there is not a lot more you can do with the present stator except to try some form of boost circuit, assuming it is already star connected.

yeah, I agree. It is performing better, still not at the level I need, tho.
Basically, here are my options:
1. increase the speed of the current wings
2. change wings to faster design
3. change magnet rotors to larger magnets
4. make a different stator
I'm kinda maxed out on #1, though I might be able to think of a few more things to increase their speed marginally.
I don't really know enough about VAWTs to even look at #2, but if anyone has a faster wing design, I'd like to look at it.
#3 is easy enough (I have the magnets), just need to get 2 more discs made.
#4 is costly, cause I am out of resign, I have a lot of copper, but it is all #14, and my coil jig is preset to 1/2" thick.
Alternatively, I change this whole thing to a HAWT, but I that will require a lot of time and money and effort, and I'm not really willing to do that, at this point.
