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

Peter,

That circuit will not work exactly as drawn.  There is no power path to the top of the transistor that drives the main coil.  Also, the power to the main coil would dump right back to the capacitor through the diode and bridge.  There must be some errors in it that will have to be corrected for it to work at all.

Hi Dingbat
Yes i didnt draw the emitter connection to the positive supply,I was just wondering what the sim said, i can see what you are saying with respect to a DC supply,but i was curious about the path of spikes as the magnet field collapses from the main coil.
I am fairly confident i managed to draw the diagram as it has been built by Mike.
I would like someone else to verify my findings tho.
Still only a few days away now before i get to a stage where i have an experimental machine.

Peter,

On the schematic you've drawn, where do you want the diode inserted?

Do you want the Q3-E connected to cap+?

I'll run the sim once I know.

Hi Darren
The transistors are all connected up to the usuall power rails so yes Emitter to + cap.i am pretty sure the diode goes in the right hand side of the bridge.
Thats great
Thanks
Peter

PS how do you simulate the timing for the SSR firing.with respect to the main coil firing.

ok Peter.

I've already done the sim according to that. What points would you like to see probed?

Timing is easy. I just monitor Q3-C with one probe, and the output of S2, which is in place for this sole purpose (you can use your S1 also). S2's output is a nice clean pulse, and I adjust the phase until the switch closes just at the instant L2 collapses. I've attached an example. In this, you can see that the timing should be advanced 2 or 3 more degrees still.

PS. What I've looked at so far doesn't look too pretty
