Calling k4zep and all,
Was fiddling with a posting and there you are, prompting me with your friggin'

... compensation winding ...

Right then:

Do as if you would prepare a bifilar generator coil. So, wind 2 parallel wires A and B onto one core. But don't connect them to each other once you are done.
Instead: Connect coil A as a normal gen coil, i.e. connect it to the FWBR and the load.
Now the ends of coil B are still open. Connect them to each other, i.e. shortcircuit coil B (can also wire a cap into that short circuit).

What benefit may be achieved?
Well, the phase-shift (read "delay") of the current in the "loaded" wire A is a certain amount. 'How much delay' depends on the impedance of the load.
The phase-shift of the current in the short-circuited wire B is not the same as in wire A, because they are not connected to the same load - actually there is no load on B at all; B just feeds into the cap, in case you have chosen to wire one into that short circuit.

If the phase shifts of the currents in coils A and B are such, that the current in each coil cancels the magnetic field of the other, then you would be Lenz-free (at a certain RPM).
I think one can use the cap to tune into that situation.??!!

@Penno64 . I feel that I speak for many others when I say that the momentous revelation that you led us to expect is to say the least disappointing . We have been aware of the possible use of multifilar windings from day one more or less .  OK , you got this straight from the horse`s mouth , but you promised not to divulge the details . This then puts you in a privileged position . The question is , how will you use that information . If you use it to build a self runner , are you still going to withold these details . If so , the benefit to the forum will be zero . I can give information about the secret of this device . It is all in the coils , cores , wires , magnets and electronics . After all we all know where the needle is . It`s in the haystack . How can a thing be lost when we know where it is ?

Hi Oscer,

Now your thinking!!!!! If I find something that really works, all will know ASA I can spill the beans.

   Just for kicks and jollies, how about a parallel and a series cap? The parallel would cause a ringing frequency say 6 times higher than the rotor pulses. The series cap would allow 'that' frequency to pass on to the fwb. Again, have to be calculated for the load present. "Tune under load" was his exact words, right?

I looked all over the garage for more relays to steal wire from, I now have 7 sewing machine bobbins full of what i think is 36ga. wire. I am working on a twisting jig to litz the wire on the fly instead of trying to find a place to string out the 300+ feet of each spool. But before I twist this up would it be better to add an 8th wire to the group or run with 6? I will post some pics of the twister when it is done.
Peace

edit: Do the wires have to be twisted together? I know in a window motor it works better to not twist them together?
