SMOT Triangular Enclosure Variation, Closed Loop?

[jeffc]

It would seam to put a upwared roll at the D positon at the end of the ramp so the inerta would be equvelent to the speed of the ball and magnetic force of the first permenet magnet to catch and throw to ball to the next PM and so forth till it repetes. thake a strip of sheet metal and try it, roll it at the end with different radiouses. A small radious will slow the ball down and a larger one will speed it up till the inerca is balenced over the curve and magnetic flux feild to the next PM .

@Motorcoach1
Thanks for the idea about the sheet metal, I?m going to try it.  I?m working on a few designs that will allow me to vary the key factors like inclines, heights, and with your idea I can modify the radius of that curve too!

What if we tried these ideas, but add zero friction?

Zero friction would be very nice.  But, sadly it won't happen!   

But wait, physics doesn't say almost zero friction isn't possible. 

I'll take whatever physics is willing to give!

Hi Jeff,

If you are not very keen on reading German language at this site: http://www.hcrs.at/SMOT.HTM you may use a free online translator like this:

On the right (upper) side you can see Free Text Translator Free Web Translator   and by choosing the latter you can copy the Austrian url and choose the translation direction.

Thanks Gyula,
The translator worked quite well.  The variations taken by the author were instructive in helping me try to design around the same issues he encountered. 
Knowing what DOESN?T work is very helpful at this stage so that I don?t waste time tinkering with impossible configurations. 

Of course, I?m not sure this is possible to begin with, so it may just be a learning experience.

Regards,

hi jeff ........ your point (F) --i dont dismiss the idea and yes it has its merits and might work. However i see a problem with your verticle drop out between (F) and (C).
You will need to gain enough height to drop out of both force fields and still have enough energy to get it back to the start.

I have another theory for you to ponder on .....I'll explain my thoughts on this first.

Any magnet has a force field that will attract a metal object toward its centre . So it stands to reason that a heavier mass will travel past the centre of attraction.(Inertia/mass ect) .  Beyond the centre the mass will run into resistance becos the centre in now behind it and the attraction is now in the opposite direction.

Imagine a falling object from space ... it will be attracted until it reaches the centre of the earth (theoretically) after it pass the centre, its travelling against gravity.

This is the way I think about SMOT .....your ball bearing needs to exit just after the centre of the force field. Its got a great 'run up' and needs to exit before it gets slowed down.

I thought about this a couple of years back and came up with a different approach. Never got round to testing it. I'll try a draw something here ......

                                          RAMP  ----->   /    --------------------------->

        <------------------------------------------------------------------------

Half way through your Smot build a ramp .......let your bearing gain speed -hit the ramp (jump up)and hopefully be elevated to point (H) on you circuit /track let it roll down to the start again. It should hopefully clear the force field ..... dont elevate your SMOT let it gain as much speed as possible. Kinda like a sling shot around the moon idea!


hope you understood that

cheers

Don,
Thanks for the detailed post.  I?ve been concerned about the ?escape velocity? problem from the beginning, so your input on this is valuable.   

I?ve received some feedback that the SMOT configuration can produce quit a large acceleration and that the bearing might even hit the wall of the triangle enclosure.  I think ultimately there will be many factors including: incline, magnet strength and arrangement, bearing mass, friction, and probably many more things.  So I?ll just have to experiment.

I understand where you were going with the diagram.  Using a ramp to escape the magnetic force is an interesting concept that I could try to apply to the triangular model I?m building.  I?ll add that to my testing configurations!

Deleted. Debunked my own idea.
