Maybe possible idea for duplicating effect of Holcomb and others

Hello to All,

@Citfta and @Jim Boot:
Sorry I could not get back to you before, I was very busy.

Ok, so, related to my Scope ground and Mains Ground...yes, they are connected.
Meaning, I have everything as it came from factory, no modifications.
The PSU I am using to turn Alternator as Motor, is a 60V/10Amps switched...and I have noticed whenever I am running Motor at 10 Amps, PSU goes into "High Heat Dissipation Mode"...so, the cooling fan automatically turns on at top speed while I am driving it...
It is obvious that it is driving it at "Max Load" conditions.
The other PSU I have, the 30V/5 Amps will NOT even turn it...So, that is the one I am using to feed the Rotor Coil.

This heavy gauge, small number of turns (4-5) winding on the Alternator, which results in like 1.0 Ohms or so per Phase-Coil, is NOT designed for the purposes we are looking for, or, to see it as getting Induction on a Secondary Coil(s) successfully.

It was just shown for the purposes of seen the sinewaves, which are alternated at identical off phase angles...plus all other spec's.

I have checked if it turns a small magnet at center of Hollow stator...with this OEM Winding, pulsing it with the ESC...and it does not even move it.

IMHO, the magnetic field generated by this OEM Windings, is not strong enough, as to reach the center of Stator.

It works perfectly well, if we could make a specific rotor where magnets (or the way the Claw Rotor is designed) are very close to stator coils surface.

Hello All,

Here is a CAD Image I made about the way a typical Alternator is wound...it may look "complicated", when looking at the whole thing, but it is not.
If you all notice, each phase winding comprehends Three (3) Tooth and Four (4) Slots, and are "alternated" with the next phase winding by One(1) Tooth.
This Stator is 36 Tooth total, like most Alternators have (and to me, it is the ideal core frame).

So, you start by Phase#1 (Green) where it is written, on left of diagram, which is the closest to the back wall of Stator.
And you start by winding CW first coil, then next coil (which starts in the same fourth slot) is CCW, and so on, third coil would be CW....until you close the loop with Coil#36 which must be CCW.
Same thing with Phase#2 (Blue)...in the middle layer of Stator frame, it starts One Teeth away from where Phase#1 started, but winding it CCW.
Then comes Phase#3 (Red), jumping one teeth away from Phase#2 (Blue), and first coil of Ph#3 is wound CW, same as Phase#1 (Green).

Point here is that we could modify this original winding, in order to fit the width of each phase of our future center static rotor configuration...unless you could find a rotor with 36 Tooth from a brushed motor...but I doubt it could be found on this size.
And of course, I will be winding the Inner Static Rotor frame, the same way as Outer Stator...meaning, with the same Three Phase winding configuration.
But, we will need to try to "match" each Phase from Outer Stator with the Inner Rotor...

In my case, the inner rotor I have, which fits perfectly well is 20 tooth...so for me, the three tooth coils/four slots per phase, on outer stator, will not work...
But, no sweat, I can make each phase coil to comprehend four (4) tooth/5 slots, instead of three/four....have to make it on CAD first...working on it.

What is the armature out of? It's a bigun.

Hello there Jim!!

Sorry could not get back to you before Jim...yes, that rotor armature is off an automotive radiator cooling fan motor, it is the type that looks like a flat, pancake motor...unfortunately, I believe, (not sure though) these motors are only build for US made vehicles, like FORD, MOPAR and GM...

Actually, it is possible to make a similar circuit both on thyristors, and on gas thyratrons and even neon
lamps. I think. And that will be rotating.  I admit that with the worst characteristics. But it will.
Something similar I had  done. These are called three-phase ring multivibrators.

Hello "Ufo",

Related to your above statement...Yes, correct, it would be very hard to find a 36 Tooth Rotor, which happens to fit inside the Outer Stator core...
HOWEVER, You must have in mind that the number of tooth for that Inner Stator-Rotor MUST BE divisible by the number "3"...like 18, 12 or 9...

And of course, I will be winding the Inner Static Rotor frame, the same way as Outer Stator...meaning, with the same Three Phase winding configuration.
But, we will need to try to "match" each Phase from Outer Stator with the Inner Rotor...

Correct so far...

In my case, the inner rotor I have, which fits perfectly well is 20 tooth...so for me, the three tooth coils/four slots per phase, on outer stator, will not work...
But, no sweat, I can make each phase coil to comprehend four (4) tooth/5 slots, instead of three/four....have to make it on CAD first...working on it.

Yeah, yeah...Ok, So, point here is that the 20 tooth Rotor config -you were thinking before- will NOT work!!
And yes, I already did the CAD drawing for 20 T...it will NOT work...
So, I did it based on 18 tooth...which is divisible by three (3)...and allows to wind six coils for each phase...for a total of 18 coils.
Since You did not have an 18 tooth available, which will fit inside the stator cores...so I went back to the Modular Isolated Elements scenario you had before, and adapt it to the Inner diameter size of your Outer Stators.
Now, on the Outer Stator Winding, I just had to move ONE SLOT back, Phase#2 and Phase#3...in order to match properly with the Rotor winding angles config.
But, leaving each coil wrapping Three (3) Tooth, like it was shown originally on your Alternator Winding Diagram...
It should work now...

You are welcome Ufo...

  ...sorry guys, but I had to quote myself on my post above, in order to correct some things I wrote previously...may sound a bit weird...lol.
