Working SMOT ramp from Tom Ferko ?

[hartiberlin]

Hi All,

Here is a video clip of the motor device in operation with 2 fingers. I am making the needed part to see it as a self runner. I am not pushing, pulling, or twisting a thing in this video. All skeptics please note that.

Hi Tom,
looks nice,
butaren?t you pulling the rod with the small magnet up
some times during the revolution and later pushing it down ?
Or does that go by itsself ?
Otherwise why are you still holding it with your hand ?
I have not quite yet understand the underlying principle...
Is any magnet on your turntable turning by itsself or
is only the turntable turning ?

Where is the ratched build in ?
Into the turntable axis ?
Many thanks.

Regards, Stefan.

Hi Tom,
I wonder, why there are always forces to repell the 2 fixed big magnets
when you lift and descend the smaller magnet ?
Why doesn?t the whole setup compensate the forces by itself ?

Are the force vectors not compensating each other ?

Is the wooden rod, where the smaller magnet is fixed
at rotating by itsself or is it fixed to the sew-saw fulcrum ?

How much energy does it need the see-saw
(small magnet or wooden rod)
to go up and down ?

Hmm, in the video it looks like you don?t put a lot of
force into it to press the see-saw up and down
and the turntable still has a good torque.

Hmm, please post more info.
Looks very interesting.
Many thanks.

Regards, Stefan.

Hi  Mramos,Sean, and Stefan

All the magnets I used were just ceramic ring magnets.  I never tried big neos yet but that can be easily done using this motor concept.  Make doubly sure all magnets are fixed in place securely or you might be eating them when this motor comes up to speed.  And it will.  What you saw in the movie clip was its slow speed with my two fingers trying to follow the turning axles cone shaped orbit.

I used two turntable ring magnets and stacked so each one had 3 one inch thick sections.   Two 3 inch thick, 4.5 inch diameter magnets spaced 6.5 inches from each other on the turntable.  180 degrees apart. You can experiment with whatever you have to come up with any working unit using this concept.  I found plastic pipe straps in the web Mcmaster - Carr store that held my turntable magnets in place. Different sizes are available.

The magnet on the pointed axle shaft arm was smaller than the turntable magnets. It still was a "HEAVY" stacked group of arm ceramic rings.  Heavy is imprtant here.

What I found was this:    Some weight you put on the axle shaft is centered in the direct center of the rotating turntable via the pointed shaft tip. You need that weight to keep the axle tip inside the center V notch and the ratchet head so it stays in a TILTED position . All weight is taken up by the Lazy Susan turntable bearings so no need to worry about any amount of dead weight you install on the axle. Those bearings can be made of steel by the way. No other components are ferrous.

However ---The most important part of the total dead weight of the entire driver shaft assembly "ALWAYS" -- "LEANS" by "TILTING" toward a given rotating turntable magnet.  Thats accomplished via the single magnet arm permanently attached to the axle.  You will have to experiment with the arm height and whatever dead weight you place on it.   The more arm weight the greater the turntable RPMs.

I can take closeups shots of any device part I made so far and used in the movie clip you saw.

Let me know what you need to see.  I hope Sean replicates this or for that matter anyone else thats interested.

I plan to bridge the turning turntable with a section of wood and secure its ends to the permanent base you see the turntable turning on.  That wood plank will have a very large cone shaped hole drilled into it. its inside walls will be very rough.

When the ratched head is placed inside this hole the soft rubber O ring around the ratchet head will grip the rough inside walls of the non rotating hole.  Now I can let go with two fingers and let the now TILTED axle shaft do its own thing.  A finger free self runner.

Need good ideas about a way of doing this short of using a cone shaped rachet head and inside cone walls that have gear teeth.   Thats an expensive way to go.

All magnets rotate with the turntable and does the driver device.  I am holding the thumbwheel ratchet with two fingers. That ratchet is mounted on the top of the brass axle shaft you see.  In the movie clip if you listen carefully you can hear it screaming preventing the magnet arm from going the other direction.


I cant really keep up with the perfect cone shaped orbit demanded by the axle shaft with my fingertips. I am a drag on the motor device and the arm magnet going up and down as you saw in the movie clip is a result of my jerky efferts to follow a perfect orbit.  The motor idea even works with all that!

I hope all this info helps.

Hi Guys,

You might say that gravity is playing a big part in this motor design also.

Its a marrige of gravity with permanent magnet power.

Can anyone think of a good sounding name for it other than motor device idea ?

Hi Tom,
so all 3 magnets in your device rotate ?
Can you show this in another video, where you tape some e.g. white
tape onto each magnet, so one can see them rotate ?

Where is exactly the ratchet located ?
a few more pictures would also really help
to understand it better...
Also your upper drawing makes not much sense
to me, when I watch the video...
Was this an old idea ?
Where are the lead pieces in the video ??
