Hi there Jack, well first off, I don't expect you to just give away all the vital 'secrets' to successful motor design. But I don't really see the difference between the Jack valve you posted before And the design using washing machine cores. Ok, the place of the magnets is different. But it is still the full magnetism of the magnets combined with that one of the coil going through the rotor combined. Should give a 4 times stronger net result when compared to the coil alone based on the force squared law of magnetics.

Don't really know what you mean by "You must have the magnetic pull through the rotor, you get both sides of the rotor pulling at the same time"
I mean isn't the magnetism always 'puling through the rotor' since it is wanting to close the magnetic path?

Hello Jack here is another thing I would like to discuss/suggest.
But first I should make clear that I in no way are attacking your system in any negative way, its a great system. This is a "I'm only trying to help situation".

Well now. On thing I have noticed for a long time is that in my opinion your rotor design is not really effective.  especially when compared to the Flynn rotor/motor system. To me the reason why they get 1hp out of a 3.5dia systems is because they have a more advanced rotor system. Your rotor can only be fired twice each rotation(per valve). Well as you can notice in the attached Flynn design, that they fire like 7 times each revolution, and with 3 'valves' simultaneously. In other words they compress the combined coil and magnet added flux strength, more times per one revolution. They have a much higher power density in one revolution. Now, I have made you a rotor suggestion that may or may not be interesting to you. But it will allow you to fire the valve MUCH more times in one revolution. Of course this asks for a higher impulse frequency, but this is no problem even to regular silicon steel laminates. Yes it is only a fast crude demo and will give saturation problems in this exact layout (unless you lower you combines flux strength) but I am sure you get the idea/principle of how/why it works.

See also the attached movie.
Thanks

Hallo Jack and thanks for your input. One thing I find curious. And that is the required low speed of the system. I mean this silicon steel is used at 50 and 60hz and should be reasonably good up to 400hz. And running a motor at 1500rpm is like 25hz (or 50 depents how you look at it.). So you are way under the rating of the silicon steel. It kind of sounds to me that the valve has a problem of not fast enough collapsing the fields. Remember once the coils field collapses, the flux of the magnet returns there (through the coil/core area). It is very likely that this action in itself is an 'power generating event', that sets an counter flux up again. So in other words the back emf of the coil, and the generating event from the 'returning' magnet's flux, severely restart an instant "flux shutdown" in the system hence the need for a low system rpm.
Maybe
