Hi all:
   Just wired up the circuit and have a mess. OK, probably did it wrong. So I went back to the diagram that mrd has for his avitar. Pondered that for a while and then had to go over to the german feed to get ottos last rendition and it shows the same thing. I am at a loss here on this. As I can see the way its wired, the six and four inch loops are just that loops. one tied to the "0" and the other tied to phase. That not having any connection between the two. If this is supposed to be a mobius then the two coils will turn into one long piece of wire with each end tied to "0" and "phase".
   Need to clarify just how this is wired before I do it again.

Hello,

HEEEEEJ GK, have you a fire extinguisher? Thanks God you use "only" a TIP transistor.

Hi All,

Since it is still not clear what is happening, or if there is a rotating magnetic field or not,  I am throwing out this circuit that I will just call an excitation circuit.

Ther circuit is auto-starting and after 3 bits will produce circulating "1"'s.

A 74HC164 shift register should be able to be clocked up to 50 MHz.

The 74HC27 NOR gate has a propagation delay of 8ns and rise / fall times about 7 ns.

This circuit will fire each FET sequentially, one after the next.  The pulse width depends on the clock frequency.

Enjoy, Earl

Hi All,

here are some further refinements.  The first circuit has no dead-time between each FET firing; the second circuit has a dead-time equal to one clock pulse between each gate pulse.  With 8 stages, it is possible to increase the dead-time to 2 clock pulses.

Enjoy, Earl

Hi,

forgot to say that the green colored lines have been indicated for anyone who experiments with 4 coils, spaced at 90 degrees.
