I'm adding a couple of  diodes to the setup, called "booster diodes".

In theory they deliver 10% more power to the WFC when any third harmonic occurs.

@Webmug
Very nice setup!  What are you using to generate your GATE and PULSE frequencies?

Right now I'm building this improved setup.

For the same number of turns and wire thickness: DELTA gives 1.73 higher power and amp draw than STAR
DELTA Kv (RPM)  = 1.73 higher than STAR Kv while the Kt (torque) = 1.73 lower
With a STAR connection, 1.732 more turns need to be wound to get the same power (and Kv) as with DELTA
In case you're wondering: 1.73 = sqrt(3)

if you do delta then you have no neutral to connect to the negative tube? what do you do instead

Have been working the alternator for some time now.
Also did some rewinds and practiced on the small cores.

First one I like the best, cut the standard winding at the half way point around and tapped that for neutral.
That will work with Wye or Delta.

Larger alternators come with bifilar windings.
I have the diesal alternator coming and the core will be near twice as large.

For testing purposes I pull all the wiring outside the alternator and make the diode and connection terminals outside.

GM si10 alternator is 42 poles. Kevin West does a lot of neat things and on the si10 used only 36 complete wells and the last 6 are just half the winds.
Meyer used a Ford diesal alternator large core and large case 36 wells and rotor is 6 magnetic poles each side, 6 N 6 S.
The one in the picture is a small case Ford, 36 wells and poles.

WEBMUG sorry to post this in your projects, I will remove it if you want.
