Thanks for the vid ufo. May I ask where you have the probes?

Hello there Jim!

Simple connections...Probe 1 > Phase A, Probe 2 > Phase B, Probe 3 > Phase C, A>1,B>2, C>3
All probes ground clips connected to Common "Y" Positive point...

See image.

Hello All,

This would be my next project...it is a Stator from a small alternator (from a VW 1.8-2.0 Engine)...but I was able to find a Brushed Armature which fits perfectly well inside...
Stator have 36 tooth, Armature 20 Tooth...So, the Stator would be spinning the Field...and inner Armature would be the Output.
I already stripped the Alternator Stator, as you could see...then doing same to armature...to rewind the whole assy my way...
And driving it with the same 3 Phase ESC.

Let's see how it goes.

Why isn't that creating a short with your ground probe on the positive of the power supply? I'm a little confuzzled.

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

Have a look at this patent application that Solarlab talked about a while ago.
If it works it could maybe be better than Holcombs.

Hi Jim,


Any time you are working with motor control circuits you MUST make sure your scope is isolated from the AC mains ground.  I don't know anything about the power system in Australia so I can't advise how to do that.  Here in the US we either use a 1 to 1 isolation transformer or a short extension cord with the ground pin removed.  Of course when working with real motor controls the ground pin of the scope can be a hundred or more volts above earth ground so you MUST  be very careful to not make any connections when the circuit is live.


Thanks to you and the other's who are working on this.  Together who knows what we might accomplish.


Take care,
Carroll

thanks Carroll, I’ve been measuring across g&d . I thought there must be an isolated ground looking at ufo vid. Enjoy your trip

Hi Ufo.


Thanks for posting the screen shot of all 3 phases. I have been studying it some and I think I understand how it works.  Next week I will be back home and after I get the circuit built I will have a better idea about it.  I think we can clean up the signal some.  We might have to leave a little of the spiking in there as that might be part of the triggering process.


Thanks again,
Carroll


PS: Went down to the Swiss Alps today.  Germany is certainly a very beautiful county.

I've been wondering about the spikes. Was going to suggest using a free wheeling diode (FWD) across each phase winding. That would certainly reduce the V spikes, but could interfere with the primitive sequencing method. The lack of FWDs and high gate resistance (slow turn-on) causes a lot of device heat (losses). It's a neat little build, but unlikely to be practical in a 'real' device.

Wonder how ariovaldo is doing with his VFD?

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.

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.

Ufopolitics

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... ;D
