Working SMOT ramp from Tom Ferko ?

Hi All,

The plastic tubes can be ordered from McMaster - Carr. They have a web site .  Different sizes are available.

I used the cheap ceramic disks which can be bought on Ebay in lots for a real good price.

I have about 2,000 of these disks on hand so thats why I am using them.  Any long rod magnet can be used.  Just stack them with wood or plastic seperators every one inch.     Why?

This is a long rod version of a Tomi track. Read up about the Tomi track on the web.

The center point of any "LONG" rod magnet without seperators is the weak spot and magnetic related travel stops there.  Add the spacers evenly as illustrated and the center point of your stacked rod with seperators in it will not have that stop point in it.

The Tomi track has a lot of bad traits which I wont go into.

I will elaborate that the so called "sticky spot" is where the big pinchoff or bottleneck occurs because two powerfull lmagnetic fields basically push your magnetic vehical ( runner magnet ) inwards from BOTH sides.   

I never really understood why a sticky spot - but it finally sunk in one day. So simple.

The stagger track concept works around this entirely.  Notice I am only using the North( ONE) side of the Large ring magnet and not the South side. 45 degree rod angle sets ring movement.  No sticky spot this way.       Tom

Hi Tom,

It looks like you may be onto something here. One thing I did notice is the similarity of your stagger track configuration to one of Eric Vogels' multi-track Minato wheel setups.



Here's a video showing one of the wheels he made:

He had problems closing the loop with his wheels although I don't remember if he tried closing the loop on the multi-track ones. The other big difference between his design and yours are the spacing and proximity of the track segments. I believe that your design is much better because the magnet tracks are far enough away so that their fields do not mix and kill the effect. This is something I observed when playing around with my arm-ramp test for the 90 degree rule. I noted that I always got strong kicks when the magnet was pressed through the gate using the lever, but if I used a rotor with magnets on it, the gating became less and less powerful as I added more magnets around the circle. I then did simulations and realized that it was the mixing of the fields that was killing the effect, so in my case, I would need to use shielding the isolate the fields of the magnets. This probably does not directly apply to your setup though but I will whip up a few simulations of the track magnets so we can see what the fields look like.

Hello,

Here is a simulation of the track in your picture using the same dimensions as your magnets. I'm working on a simulation of a circular (flat) version that I will show next.

Good News, The circular version's fields seem to look very similar to the linear track. Now I'll try to duplicate the linear track in the 3D simulator to see what I can come up with.

God Bless,

Hi Jason,

Great Artwork,

I dont have the software program to do that and glad you do.

Can you illustrate a total motor idea rendition showing a centerpoint with two long arms attached to it.  At both ends of those swinging pivoting arms a ring magnet would be attached in a vertical position.

Now take the 45 degree vertical rod setup made in a circular fashion and and center it around the outsides of the ring magnets as close as possible without touching  This should portray what the motor might look like once completed.    Tom
