Working SMOT ramp from Tom Ferko ?

Hi All,

Here is exactly how to rotate a large ring magnet from left to right.

All the stacked disk magnet ends facing you are South poles. The track illustrated is in a vertical position.

They will be facing your huge ring magnets North pole.

You will have to space the ring magnet and track apart according to what you are using.  Make sure you are trapping your disk magnets between layers of clear plexiglass or they will take off as soon as the ring rolls by.

The ring magnet will roll from left to right.   I did this with ceramic disks.  If someone has enough neodymium magnets This should be very powerful.

Have fun guys.   The cat is out of the bag.

Hi Tom,
did you now change the position of the stator magnets ?
Earlier you had them rotated by 90 degrees, if I am right ?

Can you post a video showing your roller magnet getting accelerated this way ?
Are there any sticky spots at the beginning or end of the track ?

Many thanks.

Regards, Stefan.

Hi Stefan and everyone,

Yes I had the track magnets facing the other way but I soon learned that the ring magnet only rolled so far down the track and stopped.  You have to have a long track to see real results.   A short track does not cut it.

The way I have my track setup is easy for me to experiment with different track magnet combinations. I just remove the plexiglass cover over all my 45 degree offset track magnets and swap them around to see if the large ring magnet likes a different magnetic signature to roll on.

Its really ironic -- If you look real carefully at the track configuration you will see is has a lot of the characteristics of the Perendev motor rotor construction as far as angular magnet placement goes.

I knew about the Perendev motor but was not really into its construction details.  At that time till present I had been pursuing just how to magnetically roll a large ring magnet.  I knew it could be done as I posted a movie of my first attempt. That linear setup could not be made circular but it sparked my thinking.

After I did a lot of experimenting I came up with the configuration of track magnets that worked using a 45 degree offset pattern.  The Perendev motor uses a 30 degree offset and all its magnets are also tilted a certain way.  The Stagger Track magnets are not tilted at all.  A internet freind of mine pointed how close both magnet patterns match to me. 

I really was surprized at how similar the magnetic patterns are as I came onto this from a much different perspective not even dreaming about the Perendev idea.

I am a rather slow worker and will post a movie of the track in operation.  Still have a few things to do.

I hope EVERYONE with a lot of neodymium cylinder magnets gives this concept a try and posts a movie also.  Any neodymium track should really haul the ring magnet.  I have thousand of ceramics so thats what I used to experiment with.

You asked about the ring magnet starting the track.  Its DRAWN STRONGLY INTO THE TRACK BY MAGNETIC ATTRACTION.  You dont have to force it in.  Then it runs the tracks lenght.   At the end of the track if the ring magnet has enough built up enertia it will leave on its own.  If the inertia of its moving mass is not enough it will bounce back because remember the track works by attraction only. 

I believe that this track can operate forever if made in a circular fashion as the ring magnet always has the GREATER magnetic attraction forces in "FRONT" of it with repel forces not even in the picture.

I have to point out one thing.  I am using a long lenght of cheap plastic PVC pipe to guide the ring magnet while its rolling.  The pipe is placed between the ring magnets North side and stagger track. You will have to determine the best distance using the materials you have. This will keep a minimal rounded area for the ring magnet side facing the track to slide on as well as keeping the magnet rolling straight and true by itself.

Think of making what you see into a drum or cylinder configuration and your imagination can go wild.   My fondest hopes are others give this a try and just maybe soon we can have a working motor.

Hi Guys,

In the very last power track jpeg photo I illustrated I made an error.  As shown the ring magnet will travel from right to left. Not left to right.

A couple of other notes I will share.  My 7.5 inch diameter very heavy ring magnet does travel the track much better than my 6 or 4.5 inch ring magnet.    You will have to experiment with whatever size magnets you use to get maximum results.

I have my 7.5 inch ring magnet North side 4 inches away from the tracks face. At that distance it ran the track the best.  Get the ring magnet to close to the track and it will slide sideways and attract hard onto the plexiglass covering the track magnets.

I use rubberized  non slip grip tape on the circumference of the ring magnets.   Tom

pleasepleasepleaseplease hurry making the video! i'm so anxious to see it!

also, here's a video of my smot (nothing special): http://video.google.com/videoplay?docid=-8651229076711578154&q=smot&hl=en
