What do you see when a scope probe (10X) is touched to the laminations?
--> I see chaos-will post screen shot today.

 

Tinman,

Thanks for fixing the schematic...

I now have all three stators stacked together(all isolated),as in first picture. The top and bottom stator are in series,and pulsing a north field on outside perimeter. The center stator is fireing 180* out of phase with the top and bottom stator,and is fireing a south field on the outside perimeter.The center stator is fired via a pnp transistor,which is triggered by the SG.The outer stators are fired up via an NPN transistor,and the signal to the base is from the inductive kickback from the center stator. So as the center stator switches off,the two outer stators switch on.

The scope shot below show the traces across a 10 ohm resistor on each probe.The ground of both probes are on the bottom stator core.The blue trace(probe) is on the center core,and the yellow trace(probe) is on the top core. The scope is isolated from ground(grid),via the UPS.

When you say "electrically isolated" you are talking about a continuity test: Low voltage DC from your ohmmeter, right? Do you have a "highpot" tester? Are you working at high frequencies?

There is "isolation" and there is true isolation. It is inevitable that your windings and your cores are _capacitively coupled_ and you may not be able to detect this with an ohmmeter at DC.

Have you actually tried anything like the experiment I suggested?

Seriously? You don't know why I suggested this experiment?

Well, I guess it's kind of like Jazz music. If you don't get it, I'm not going to be able to explain it to you.

Why don't you just try it, and see what happens.

Below is the full schematic. One interesting thing i found was it will self oscillate when the SG is disconected.Im guessing that there must be enough capacitance between the collector and base of the tip36c to keep the oscillations going.It will self oscillate around 9khZ.

Set up as pictured below,there is no need for the inductors across the LED's,as the LED's will light extreemly brightly on there own.
The whole system is now completely ground isolated. Using a small ground stake in the garden bed,the LED's will also light between the ground stake and stator core's,and can be either polarity to do so..

It is also not frequency dependent,as will work between 150hZ to 90khZ. However,there are frequencies where the LED's will go extreemly bright and then blow.

You will also notice in the schematic that the top and bottom stator are wired in series(polarity correct). This shouid mean that there polarity and potential  is the same during each cycle,but still the LED's run quite brightly between these two core's

The inductive kickback is being quashed via B2,and now peaks at battery voltage(around 12.4v).At some frequencies when the LED's are conected,the P/in will rise slightly,and at other frequencies the P/in will go down.In either case,the P/out to B2 never changes-checked with scope and CSR.

The low-value capacitors formed by the cores and the windings are conducting the oscillating signal and allowing power to leak to the LEDs. And/or, you are experiencing insulation breakdown at a higher voltage than your continuity checker is using.

Do the white plastic bobbins fully surround the cores, or is the winding wire in contact with the metal of the cores at any point?

TK-i wish you could see the video-->that would answer a lot of your questions.
The white plastic is 2mm thick,and is mould injected around the core.There is no way in hell the windings are ever going to short to the core. I have tried some time back to remove the plastic insulation from the steel core of one of these stators-->it took me nearly a whole day.Two of the stators are 60 series stators(top and bottom in my setup),meaning that they ran on 240 volts,and the third is an 80 series stator(earlier modle) and ran on 120 volts(center one in my setup). Im using 12 volt's.

Looking at the pic below,how can the two cores have any potential difference?,as they are identical in all way's,recieve the same electromagnetic pulse,and are in phase with each other.

Chek for cooling @tinman
