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

Hi Darren
what is keeping the voltage across the cap from falling, i presume there is a constant voltage source feeding it.

Yeah, as I mentioned, no cap in this circuit. Source is a battery.

OK great stuff
I would be interested in the timing of the SSR to minimize the current consumption.

Cheers Darren

PS hopefully those dam meters will arrive, i still need to get a scope to see what will be happening with my proto type.
It is so annoying sitting at work doing very little at the moment, i could be at home assembling.

Hi Darren
Not sure if this is what you are looking for

Air wound coils, no matter how closely coupled, will have a coefficient of coupling well below 1. For most cases, values of k from 0.3 to 0.6 are common with air wound coils. Table 1 provides a sampling of some variations in k and M with different values for L1 and L2.
   Sample Values of M and k With Sundry Values of L1 and L2

L1          L2          LTA         LTB         M           k
Values yielding k = 1
5           5           20          0           5           1.0
8           4           23.32       0.68        5.66        1.0
10          1           17.32       4.68        3.16        1.0
Values yielding M = 2.5
5           5           15          5           2.5         0.5
8           4           17          7           2.5         0.44
10          1           16          6           2.5         0.79
Values yielding M = 1.0
5           5           12          8           1.0         0.2
8           4           14          10          1.0         0.18
10          1           13          9           1.0         0.32

Note:  Values of L1, L2, and M are inductances and may be read as Henrys,
milli-Henrys, or micro-Henrys, so long as the unit of measure is the same
for L1, L2, and M.

Peter,

The timing is straight-forward I think.

Set for S1 "ON" just before L2 collapse. Turn S1 "OFF" before next Trigger. See the scope shot I just posted.

From what I have seen so far in my model, D2 only conducts during the transient spikes.

Obviously there is something still missing in the model, and that is the gradual roll-off after the spikes. This part is important I think because it's the ou bit as Mike implied.

My guess as to what this oddity is, is the generator voltage riding on the cap voltage. Doesn't make sense, but that's what it looks like to me.

Ok Darren.
Please note the post above about the k constant values, as i think you may have missed them because we posted at the same time.

Thanks.
