My actual experience in playing with this device showed me that this "push-pull" magnetic behavior has an overall "feel" of producing invisible gear teeth.

With the connecting shaft disengaged and both wheels free to move, I...

1. rotated the single magnet on the vertical axis by hand and observed the large wheel with four magnets and

2. rotated the large wheel with four magnets by hand and observed the single magnet on the vertical axis.

In both cases the free wheel spun to match the rotation of the driven wheel, almost as if four invisible, sloppy gear teeth were in play.  The connecting shaft seems redundant.  The connecting shaft has more than four sloppy teeth on it's gears, and they are visible.  These connecting teeth just smooth out the response motion of the free wheel.As can be seen in my video, it slows to a stop when spun in either direction.

The way you can rotate it in both directions is strange. Makes me think your gearing is wrong.

if the south pole is in front of the north and south it can only rotate in one direction.

But looking at the marks on your magnets and the behaviour it look good. But it should only spin in one direction.

How is your replication progressing?

This is the best evidence I have so far.

I'm still thinking about it, I've changed the drawing every day so far. lol - The right axle and sprockets is fishy for the weaker/smaller magnets.

You might want to use better quality parts than I did.

hehehe, yes but that doesn't go this fast. I think Lego is good physics now.

I almost forgot to mention.  I made sure that there was some back pressure between the wheels before I slid the connecting shaft gear into place.  This had the effect of moving the wheel several degrees out from top-dead-center, as can be seen in the photos.  It did not, however, continue running.

Some back pressure should be 45 degrees. Maybe there still is hope. lol

Quote
Perhaps if you used more magnets around the perimeter, each rotated into the face of the wheel by the same degree in which they are separated upon the face of the wheel making a full 360 for 360.  Perhaps 16 separated by 22.5 degrees?

Good luck with that.   :)

For a closed loop setup you can get rid of 2 magnets, the primary wheel only needs 2 magnets that directly face the secondary.

The photos show that.

I have removed my designs that where wrong and working at some new.  :)

But plz do double check your apparatus.

I'm pretty sure about the single spinning direction.

*edit*

I've attached an image to illustrate how your wheel isn't perfectly pointing at the target. I had the same problem drawing it.

Hi Gaby, I'm Thomas from the Steorn forum. We've met there briefly.
Do you know what's up with Steorn? The new Steorn site is the pits, no info there, the log-in window is inactive. Is there any discussion about Steorn on this forum?
BTW I like your present design. I'm going to study it in depth. I used to be a PMM enthusiast, but Steorn turned me off.

You should build it.

PS I can tell you why it won't if you care to know ;)

On the website gaby said:
"...the magnet at the left is almost infinitely more influenced by this interaction as the one at the right." (or in this pic, the magnet in the upper-left corner(which I will call the magnet on the shaft)).
(http://gabydewilde.googlepages.com/pmm-ppm.gif)
I will refer to the other things on the bottom and right as magnet wheels.

It takes more work to get to position a3 than he thinks(see pic below for what I mean by "a3" position). as the magnets on the wheel approach the magnet on the shaft, similar poles are resisting each other all the way until position a3 is achieved.

Then once in a3, the shaft magnet will want to spin 90 degrees. The torque with which it will rotate will not be much, as this is the area on the shaft magnet which the magnetic field is the weakest.

As the magnet wheels leave a3, opposite poles on the shaft and wheel will start to point towards each other and attract.

So this is why it won't work. Two sticky spots, and not enough torque from a3 to get past either of them. But hey, if you're convinced it will work, by all means build it. ;)

Gaby, seriousely your trolling your own thread.

Build a version in the way you believe it should work post a video/snapshots etc and then talk again.

Looking at your designs it should be fairly simple.


Sidenote: I`m not saying it does or does not work.

Gaby, A good rule I find useful.

If I'm feeling hot by somebody's response in a thread, I type my reply, save it and wait a day before posting it. Usually, reading my reply a day later, I find it necessary to tone it down quite a lot, or sometimes even think it not worthwhile to reply at all. We all respond somewhat irrationally when we are hot about something, and in this case, xpenzif is pulling your string and is probably enjoying the thread immensely.

Best regards

Albert

I was being silly. You are right tho, it wasn't very funny.

Interesting, I was looking at this.

I just made this page.

The same effect can probably be triggered on a micro scale. :)

I hear I should really be using toothed belts so I just add this drawing to illustrate the engineering problem. (kind of)
