Simple to make Hilden-Brand style motor

Yeah sorry for that. This actually happened two times not the same scenario. First the 0 byte, then after I finished making an even nicer drawing it crashed without saving anything  . So I got frustrated and left it. But I'll make a new drawing now.

Edit: Oke done and attached to this post.

i_ron, I was thinking today. What if you reversed the polarity on the coil in the last experiment. What I predict is that you can barely hold anything. But it could not work due your setup.

A better setup would be using half of what wizkycho proposed namely what you can see in the image below. I and I bet others would really appreciate this experiment!

broli,

K, thanks, but I am not really following you. I think your sketch would work, but I don't see any advantage?  And yes if I reverse the polarity there is no effect.

Here is a chart to better illustrate the advantage of the power gain in this setup.
There are three patents (and/or pending) on this, Jack's, Genesis, and Flynn. This is better than
the parallel path model in that what I found is it didn't want to switch if a bar was not present. This
copy of Jack's and Genesis is a strong switcher and reaches out for the bar a considerable distance.

Pardon me if I work in imperial for some of the measurements. To explain the setup... I have used
a long arm because the core and bar are not radius ed. The Matzuo digital scale measures up to
50 pounds so is not as precise as one might wish at this level. to help out I have used a 2:1 ratio
on the arm and dived the result by two. The Matzuo is of a strain gauge construction and thus the
chain does not extend or contract but maintains a relatively constant dimension. So I was able to
use the 10 thread per inch slide directly as one turn per division, hence the .1 inch scale on the chart.

With a 1 inch square bar and 1 inch core thichness, I have started the test at .3 inch (8mm) ahead
of first alignment. That means the number four on the chart is with the core and bar edge to edge.

The test finishes with the core fully covered by the bar at number 14. The picture shows the start of the test with the bar .3 inches below the core.

Now one thing that should be clear from this dynamic test is not only is the combined force stronger but is of a longer duration.

Incidentally, the test picture is without the magnet stack...

Hey I didn't mean to kill the new list with one post!!!

Comments, laughter, ridicule are all better than silence...

What do you think? Jack?, Nali? all?

You murderer...

LOL, It just came to me that everyone is so taken with my skill and wonderful manner that they
have all quit this list and are just waiting for me to open a real list....

Hehehe, don't be alarmed by this banter folks, Nali and I very good friends from away back. He was the one that encouraged and explained Jack's valve to me. I am a retired machinist but Steven's designing and machining skills leave me in awe. His animation work has this "out of this world" touch as you may have seen. Whereas I take a more redneck approach and like to illustrate concepts with a bit of wood and some C clamps. To show the "folk" that you don't need a million dollar lab to get your feet wet.

OK, that was one reply...next....
