Controller circuit for Hilden Brandt motor needed..

[Honk]

Thanks for your positive feedback. 
The test phase will probably start tomorrow.
I have some business to take care of at first.
It will be nice to see the controller run the valves.

Beautiful work Honk. I'm truly amazed at list of features that you have in this controller.

However, I do have a comment about your test valve pictures. I always thought that starting from right to left would be the magnets, then the coil section, then the stator section. So that the magnets flux would first be going thru the lamination in the coil section, it being the closest, until the coil is turned on to switch the flux from the electromagnet and the magnet into the stator section. In JackH's original concept, he had a soft iron core completely around the magnet to stop any flux from going any where else, until the soft iron core was switched.

If I'm understanding your picture correctly, the magnets on your valve seem the be a little closer to the stator section, and magnets being lazy will flux to the nearest steel. This would seem to reduce the flux moving to the stator, since it is probably partial saturated, and also reduce the back emf.

Please excuse if this is a dumb misunderstanding on my part, but I'm really excited about JackH's testing.

Regards,

This would seem to reduce the flux moving to the stator, since it is probably partial saturated, and also reduce the back emf.

The flux will "as you say" take the shortest path, but it prefers the easiest path with the lowest resistance.
The yellow tape seen at the stator end is acctually 0.1mm (0,004") thick and this presents the air gap in Hilden-Brands motor.
The flux from the magnets will take the route through the coil core because there is no air gap.
When the coil is energized to the same flux level as the magnets it prevents the magnet flux from passing the core.
Instead both sources of flux will pass through the rotor piece at the taped end. Right pass the 0.1mm air gap (0,004")
When the coil is turned of the magnet flux will return to the easy and non gapped solid core of the coil.

Congrats Jack and Honk !!!!!
Beautiful work.
Anxious to see the two working together.
Jack hows the wire supply holding out ?
