Since I still haven't even wound any coils for this project yet I decided to check into what it might cost to have some 1/4 inch diameter Permalloy cores.  Some members here on the Garbriel device thread had mentioned some Permalloy suppliers.  After some fanagling I got a response from one of those suppliers.  I asked for a quote on 1/4" x 20 inches and they sent a quote for 1/4" x 30 inches.  $389.00 !

E2M -- was this Magnetec?  I've also found their prices TOO high.  Does anyone have a better supplier of HIGH PERMEABILITY material?

I'm interested in how much TIME it takes for the magnetic re-alignment in the material...  I think this is important, allowing us to challenge Lenz by taking advantage of the LAG TIME...  at certain speeds of the rotor (or frequencies, in a transformer like the Gabriel or earlier (Turtur/Horvath/Schnelzer) ). 

You see, it may be that "tuning for OU" involves getting Lenz to HELP rather than hinder the EM effects... by taking into account the magnetic TIME LAG in the core material. Something that others may have stumbled onto "accidently", then found frustratingly hard to reproduce.

  At least, the time-lag effect makes some sense to me...

Sorry if this is obtuse; will return to this "magnetic lag-time" point if there is interest. (I've been discussing this on other threads...)

hi JoeFR

nice work you did there - one thing I see problem with is your ammeter is pegged all the way over to the right and if there was any increase in current to the motor, you probably wouldnt be able to see it - it looks like the needle is still floating there a bit, and maybe isnt pegged to right, but having a 200ma or 500ma analog ammeter instead would be better to see if that increase in speed also means a bit more amps too...

you can calculate the watts coming out of that backemf circuit by this formula:

farads of cap / 2   (if 680uf cap that would be .00068 farads for example)

multiply this by the voltage of cap before discharge SQUARED
minus the voltage of cap after discharge SQUARED (use scope to see this voltage drop during discharge)

then multiply this by discharge events of cap to load per second..so if once a revolution at 2400rpn, that is 2400/60=40 times a second for example....

How are you timing the "cap discharge to light"? with a 555 timer or something?

What sort of SSR (solid state relay) are you using?

How are you timing the "two stage" alternating SSR output circuit?

Hi Kone Thanks

I am on holidays far away from home, so the problem is that I dont have all equipment with me here.

nice work you did there - one thing I see problem with is your ammeter is pegged all the way over to the right and if there was any increase in current to the motor, you probably wouldnt be able to see it - it looks like the needle is still floating there a bit, and maybe isnt pegged to right, but having a 200ma or 500ma analog ammeter instead would be better to see if that increase in speed also means a bit more amps too...

I connected Digital Amp meter and it reads:
No BEMF recovery just driving the motor: 101mA
With BEMF recovery to Light Bulb 24V 1.2W: 105.6mA

Can you please help me calculate wats out for the first time. I post scope shot from probe connected to C2 680uF 200V cap?

Arduino Uno

What sort of SSR (solid state relay) are you using?
The SSR are a bit overkill for this setup but this is what I have with me on holidays
The SSR model is YHD2280D ( 220V 80A DC )

How are you timing the "two stage" alternating SSR output circuit?
With Arduino

At the bottom are Scope shoots from Arduino SSR1 and SSR2 timing

@joefr.

I am very much interested in your Audrino setup. Is it possible to post your source code and hookup to it. I am presently  in one of many upgrades to latest Konehead opto setup marveling on his constant ingenuity I  hope to  have it running soon. I am yet to grasp his 5 fets AC setup without schematics,, LOL,, I recently purchased Audrino  duemilanove and would like to start using it. I see great potential and versatility in using the Audrino.
