Simple to make Hilden-Brand style motor

Ok Ron, of course, no problem it was an idea.

Any data on input and such, little scoping?

Pre tty pic ture for yu all,

This is just over one set of co ils... (one pulse)

LOL, the spa cing is to get rid - of - all the blew crap

Here it is as a generator: first pic
Motor driven at 645 RPM (approx)
No power to coils, no power to logic

And showing the fet gate trigger as a reference: second pic
Fet not powered, logic only

PROBLEMS:

The first pic shows the model running on one coil set (one side operation)

The second pic shows the clean result with a diode over the coil.

The problem arises when I run both coil sets. The one set feeds the other and vise versa, to extend the pulse with a glitch on the front to cause it to run slower with diodes than without. No matter how much I shorten up the opto shutter the pulses overlap and cause conflict.

All pics are 'over the coil', pic three, left coil set in blue, right coil set in red

It would seem that the four coil idea is not working and a single coil set with an H bridge is the "proper" way to go....?

Hi, don't 100% understand the arrangement right now. Circuit logic and coil params would help: wire, no of turns, inductance, resistance.
