Working SMOT ramp from Tom Ferko ?

@magnetman12003,

I guess, I missed something. Your last drawing appears different from the simple construction with the ring magnet and the three rods at 45o you showed a picture of.

Hi Omnibus,

That diagram was for a simulation he wanted me to do. The original track is still just what he described earlier. The completed circle is what I believe he is working on at the moment; right Tom?

@Tom,

I am still working on the simulation for the model. I got it about half-way finished last night but since the results were inconclusive, I'm going to let it run a little longer tonight to get more concrete results. Though I can say that from what I am seeing so far, it doesn't appear to be to encouraging. But don?t forget that the simulation program doesn't take into account some of the 200 known magnetic effects other than the well-defined B field interactions.

God Bless,

Hi All,

Right now I am making a long 36 inch linear track to see if any problems occur.  If all tests indicate I can move the Ring magnet freely from one side of the track to the other I will shoot for a circular form.  I have 16 rod magnet made up at this point.  I plan to layout a wood framework to stack them into as you see them on this illustration.

I might just lay the ring magnet on a 4 wheel platform over the rod magnets with the proper polarity facing the rods and see if the ring runs the track.  Thats easy to do.

The circular track will be more difficult to make.  This illustration shows my 7 3/8 inch long stacked rod magnets that are 1 inch in diameter.  My ring magnet is 6 inches in diameter.   The spacing between each rod magnet is 1 inch.


Note that only 3 rod magnets have influence over the ring magnet at any given time while the ring magnet is in motion.    Tom

Hi Guys,

I found out that the idea in my last illustration came very close but did not work out in a long run.  I made a few simple modifications that produced the results I hoped for.

What I am constructing now is based on a staggered track concept. I did that a while back but I could not find a way to make it circular.  This particular rendition can be made into a circular form very easily. It can move a 6 inch diameter -1.75 inch thick ring magnet with ease.  Get this-- Only "ATTRACTION" is used and there are no sticky spots at all.   I will make a movie of it in operation in a linear form.  If no bugs pop up within a long run I will go the cicular route.  I have the magnets all ready to mount and am cutting more track wood now.   Tom

This illustration is in color and details how the stagger track is layed out and constructed.  My previous illustration was not very clear.  The view shown is looking straight down from the topside.  The graph paper squares represent 1/4 inch blocks.

The large ring magnet ( color coded yellow - north side is red, south- blue) is 6 inches in diameter and is 1.75 inches thick.  It is free to run/roll inside the center linear track channel.  In this case that direction is indicated by the arrow.

On both sides of the ring magnet are 1/4 inch thick wood seperators running the lenght of the track ( color coded black).  An all wood channel is now formed for the ring magnet to easily roll through. It can be 2 inches tall.  This channel keeps all rod magnets from contacting the sides of the rolling ring magnet while its running the track. The channel also keeps the ring magnet running straight and true.  There are a lot of different powerfull magnetic forces at work.

The 2 inch long rod magnets are 1 inch in diameter and the colored polaritys "FACE" the ring magnet sides directly at an offset of 45 degrees as shown.

They all are layed down and fastened on the baseboard the ring magnet is running on.

I used stacked rods but a solid rod magnet can be used.  Notice how they are stagger spaced. The 45 degree offset, the polarity positioning, and the staggered  track are very important!  Any or all not done right and the ring magnet will not roll the track.

Also note how there is only staggered ATTRACTION on the ring magnet-- first one side is pulled forward then the other side is pulled forward, back and forth and so on as the ring magnet rolls faster and faster.  No sticky spots to deal with as in a TOMI track configuration.

Further testing of a long linear track run will determine if the track centerpoint is weak and if the track runner (ring magnet) can move up a small grade: Also the runner ring magnet must be able to self start from any position on the track.

I have 1 inch thick wood seperators between each rod and a clear plastic cover plate holding them down from the topside.   Those rod magnets will definetely try to move when the large ring magnet rolls the track so they "MUST" be securely fastened.           

I hope this clears things up.     Tom
