Dynamic spiral motor animation.

[kenbo0422]

In the first animation, if you turn the rotor magnet on its end, to expose both poles, it will give you a repulse and attraction to over come the constant repulsion as the stator magnets try to come back into their original position.  Reversing the rotor pole directions can give you 'forward and reverse'.  ??

I dont know if this is what you were asking for but rexresearch was down and I felt like doing some sim's anyways. (bored...)

I hope this is accurate to your design request:
(the results were inconclusive) 

Hi Dingus Mungus,

I attached a hand drawing of my understanding on how the keeper is positioned wrt the horseshoe magnet. It is intended to place for equal distance from both legs of the horseshoe magnet regardless of being put in front, or above or below of the legs. And by varying the distance of the keeper is the way to find the neutral line, see Figs 1 - 4 at link http://www.keelynet.com/energy/gary.htm  from his patent.  The keeper never touches the horseshoe magnet and its ends should be kept at equal distances from both legs. The thickness and a little bit the length of the keeper depends on the strength of the horseshoe magnet.
Notice that there is no need for the L shape endings of the horseshoe's legs. Or you think it is better to have that shape?

I can not simulate two materials on top of each other so I used the fulcrum example instead. The principles are the same though. When in the 'null' position a nail on the nonmagnetic end of the iron stator would have no attraction, but in either of its toggled states the stator iron could act as a stator magnet of either polarity and attract the nail.

By using extension of the lever one could use the fulcrum to change the iron stator from attract to repulse (like a dc motor) with minimal mechanical or electromagnetic input. This magnetic toggle switch has hit a chord with me, and I will be designing another animation that incorporates this concept. Excellent find, and sorry if I can not simulate what you were looking for.

Hi Dingus,

Ok but can you simulate two materials that are next to each other? like I show you in the picture below.
Notice that the keeper's endings should be kept at equal distances from both legs. The thickness (and a little bit the length)  of the keeper depends on the strength of the horseshoe magnet. The material of the keeper is soft iron that loses its magnetivity when moved away from the fluxfields.  The keeper has no poles when exactly in the neutral line (and its mechanical sizes are "matched" to the stregth of the horseshoe magnet) but will have poles if you place it nearer to the horseshoe magnet and CHANGES these poles when you place it a bit away from the neutral line.

Dingus, thanks for taking the time.

The Layout I had in mind was like the link I posted before and also gyulasun's above.
Yes it's very interesting phenomenon, the keeper bar it self is attracted but there is no polarity at the Neutral Line (or Neutral Plane) as also explained in the patent, and the keeper bar does not attract anything behind it. That part of the experiment can also be easily replicated as I?ve done so using a pin as the patent describes.

I was curious to see if you could model it and if the flux becomes completely "absorbed" into the keeper at that position, or "deflected" around the edges and not effecting objects behind it? or some kind of another arrangement that is self canceling?

Is the phenomenon effectively a magnetic gate? or a magnetic on/off switch so to speak?

Either way, it maybe useful in the quest for an OU magneto-mechanical device.
