Another thing -When I was trying out different connection options I found this: Connecting an additional cable from one AC leg to the middle of both coils resulted in a full sine current wave. Wonder what that does if current cancels out completely.

Watch what happens if you change your test lead lengths and/or interconnecting wire lengths.  If my hunch is right, this thing is throwing off RF signals across the spectrum since we are "virtually" shorting the coils.  That should collapse the magnetic field almost instantaneously and create a lot of RF noise (so I have read).  Also messes with your test readings fairly hard.

I am still waiting on the little radio Gyula turned me on to.  It should arrive by the end of the week.  If that can tell us what "noise" frequencies are most prevalent from this system when under load, maybe we can adjust conductor lengths to minimize their interference.

Where are our RF guys?  I, for one, need theory as well as practical advice!  I never learned Morse and so never became a HAM, okay?

Coils are wound exactly the same way with regard to direction of turns and starting location of the wire on the forms.  I have not even tried any other coil wind techniques(except the two bi-filars that are not mounted) so there is no chance I have mistakenly picked up a differnt coil.

Then the bottom coil in each pair is flipped over.  The start of the wire (inside of the wraps) of each coil is joined together.  The end of each wire (outside of the wraps) geso to the FWBR AC inputs.

So no, your diagram is not correct.

@Mondrasek: Would you like to try connecting as Xeno suggests and compare?

That would require a complete tear down.  So I am not inclined, right now.  But I welcome any input from others who can easily test both arrangements.

Right hand rule:  If you grasp one coil so that your fingers wrap in the direction of the coil, the current should flow in the direction of your outstretched thumb.

How do you get current in the second coil going the opposite direction?  You flip the coil/hand.

I am not 100% sure if the fact that the rotor magnet's different N and S poles are facing the different coils in this arrangement makes any difference.  But I don't think it affects current.  Only voltage.

Please let me know if I have gone off track.

Taking some of my own advice, I noticed that my primary Toshiba laptop PS brick was still attached to my power regulator circuit with 24" alligator clip leads.  Before removing those leads, RPM with the current light bulb load was 1820.  After removing them (connecting the PS brick coax more directly to the circuit), RPM was 1880.

Any wires in the vicinity of this device should be picking up EM noise, AFAIK.  You need to adjust and/or account for this noise.

@mondrasek:
If you don't mind. Could you please tell me if this is how you have your setup?
