Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

Thanks db.

Do you think this particular ON/OFF function of the SSR is critical to model the effect properly?

The portion of of the waveform where the ssr is ON, at the moment just shows a positive spike imparted to the existing waveform. After this positive spike, the ON ssr actually seems to have little effect on the rest of the waveform.

I believe the scope is grounded where it should be...the "common". This is also where Mike said he grounded his scope if I recall correctly. Everything should be related back to this common, not the collector of Q2. When Q2 and Q3 are OFF, they are OFF. The only path L2 has at this point to either V+ or GND is through parasitic capacitances, in and around Q2 and Q3, or assymetrical switching of Q2 or Q3.

The timing of the S1 switch is correct I believe, as it coincides with the bemf spike from L2.

I've made some good progress in the last couple hours, so will hopefulyy have something worthwhile to post soon.

Making some progress here.

I've now go the D2 shot pretty close. I've also figured out how to get the double negative pulse consistently (must use low beta transistors for Q2 and Q3!!!).

This D2 shot is with S1 triggered as shown, but with no cheat voltage. I've removed this Vcheat for now. So this is essentially Mike's circuit as published.

The spikes in Mike's shots are "stretched" or "slowed down" (lower Q ?) such that recovery after the initial spike transition is gentle and long  rather than fast and short. Anyone have an idea what causes this in Mike's shots?

No - you can simulate the timing by changing your phase and voltage, which it appears you did quite effectively.

The portion of of the waveform where the ssr is ON, at the moment just shows a positive spike imparted to the existing waveform. After this positive spike, the ON ssr actually seems to have little effect on the rest of the waveform.

I agree.  I hoped it would be a little more dramatic.  I attached an old post with Mikes "D2" scope shots for visual reference of how much his changed with and without the ssr functioning.

I believe the scope is grounded where it should be...the "common". This is also where Mike said he grounded his scope if I recall correctly. Everything should be related back to this common, not the collector of Q2. When Q2 and Q3 are OFF, they are OFF. The only path L2 has at this point to either V+ or GND is through parasitic capacitances, in and around Q2 and Q3, or assymetrical switching of Q2 or Q3.

I agree that you have the scope connected where Mike had it connected.  I'm just not sure what the original scope shot was trying to show, based upon where it was connected.  I thing Mike was responding to a request from Stefan, and didn't put the probes where they should have been.  Then Mike disappeared before Stefan could correct it.  The npn transistor in the path is a problem.

The timing of the S1 switch is correct I believe, as it coincides with the bemf spike from L2.

I agree.  Again, Mikes shots posted (the old "inverted" ones) for comparison.
