Hello all. The only reason I have yet to build this simple device is because I am homeless and poor.
Thanks alot you capitalistic pigs. :( (greedy technology suppressing dogs, the capitalist are.)
But for the peace loving communist out there, this is GNL and totally free. Capitalist can go sleep on the cold ground forever. ;)
PLEASE build and utilize, but when you do, notice how the poor are experiencing more depravity and dejectiveness - our hell for their slice of heaven.
Even the "low class" have ambition.
I work very hard even though I'm mentally disable. But in America, so few care about the homeless.
Think about it please, because too often we hear "thats YOUR problem".
I've tried to give back to the world and will continue to try. But I'm working with little formal education
and living in a world that sees me in poverty and turns their head.
At least the Native Americans helped each other build teepees and huts, regardless of individual intelligence or strength. Damn the elitist, and their greed.
Hey, all you folks have read or looked at the designs; how about letting me hear about any successes (hopefully) you've had.
I figure rare earth magnets would be ideal for the circular array.
However, they are dangerous, and if you are'nt aware of their potential risk, please don't attempt to build this project.
The whole device should be concealed within some material which has a shielding property to it that specifically blocks magnetic waves, such as lead, which may be dangerous as well.
Rare earth magnets aren't machined into triangles, from my limited knowledge, so you could fix the inner tri array with magnetised iron or something which can be easlly be magnetised to meet the design specs.

@ Fresh::
i threw together a replication-sort of, out of spare parts and my box-of-a-hundred-magnets.
but there seems to be a problem with my replicated version of the device, as the "point" of the triangles reaches one side of the stator magnets, so that the "P" side of the point is closest to the corner of the stator magnet - the rotor hangs up there, from not only the attracting forces of the large "N" magnet above it, but also the replusion from the "N" side of the rotor blades approaching the next stator magnet.
i can give it a good spin and it goes for a while, but slows down and eventually stops. even goes backwards a bit until its stopped at its "balance point".
i have tried 4 different angles of triangle magnets, even tried reversing the polarity of the stator magnets, and this just moves the "sticky point" about 3/4" across the gap.
@smokey:
sounds like you did the appropriate falseabilty test. But did you use rare earth magnets? And suppose you used a different approach then the one I've demonstrated. Maybe the principle is practical, and yet my design is insufficient .
Anyway, I will rework the design, so a big thanks for trying smokey. A big help.
i used iron-ferrite, the triangles were cut with a low-rmp tungsten cutter to reduce heat-loss to the magnetism
ive tried all sorts of things i have a box of triangles, circles, squares, rectangles (that i made most of the triangles with)
it didnt seem to matter wether i used squares or rectangles except when the size came into play.
at things would have it, the forces working against us are more intense in the area just outside the end corners of our drive magnets, having the triangles smaller than that did improve performance, but not enough to kick it past the sticky point.
i could find a place that makes string triangle magnets but i believe it would be proportionally similar just with more intense flux.
i do have about 200 small round rare earth magnets on order should be here soon, that i plan to do some experiments with.
i've been examining the flux patterns of several "linear" motor designs, and it appears there is a portion of the field, near either end of the track arrangements where the cars want to stop or slow down (a few actually launch the cars in a straight line past this point its crazy can't loop it) but if you had this set-up at a line tangent to a wheel, so that the wheel magnets curved away from the "sticky-point" before it got that far the velocity of the wheel may be enough to pull it out of the influence-field before it gets that backwards pull.
basically a linear-magnetic motor to drive a wheel.
Yeah Smoky,
no doult. But Here are a few other designs which may work better.
Try these.
The first has two positive tris' for the spinner, and positive / negative outter array (stator).
The second is a design using a single four sided ring, with a single pole representing the inner most side of that ring. In this model, the spinner is fitted with tris' close to the stator, with lead caps at the corner tips of each tri.
The lead acts as an insillator, working to keep the magnetic interferance constrained.
now if i could just figure out how to make a unipole magnet, that might work...
Easy Smokey, all you have to do is wrap some magnetic shielding around one pole. That is according to some here. :-)

lead blocks magnetic waves/fields? can anybody confirm this for me? because this would help one of my projects a whole lot.

Hi,
Short answer is: lead does not block magnetic fields any better than air. See this link for some more answer:
http://www.lessemf.com/faq-shie.html#Lead-Copper and read through from title
Why can't I just use lead or copper or aluminum foil for magnetic shielding? to the bottom of that page.
Check also this link on this Forum for magnetic shielding:

The best known shield or magnetic-blocker is the metal -alloy used in the metal casing surrounding Speaker Magnets. This shielding blocks ALL of the magnetic flux comming out of the magnet except ONE pole facing outwards towards the cone.
if you could get ahod of this alloy it would meet your needs. However this metal compount is stronger than tungsten and has a melting point somewhere above 2200F because i cannot melt it with my welding torch, so manipulating the metal to the shape you want it is a long and enduring grinding process..
@sm0ky2
Your right you can't get a ring monopole magnet but you can get very close. McMaster Carr sells a flexible magnet material that is about an 1/8" thick and magnetized through the thickness. I believe they come in 12" or 18" strips. They are flexible enough that they can be placed inside a 4" PVC coupling you could get at any home improvement store. There will be a small area where the ends of the magnet meets that may give you a sticky spot but the material cuts easily with an exacto knife and I believe the spot will be negligible. I've tried this and got similar results to your triangle experiments and really couldn't feel any sticky spot in my setup (very crude). My thoughts on eliminating the sticky spot if it did appear would be to use three strips 120 degrees apart along the "motor casing" (the cylinder that holds the flexible magnets) and set the rotor up with three crosses along the shaft.
I really enjoy this forum as much for the ideas that don't work as anything else. It saves me, and many others, from attempting things already tried. I need to get my digital camera and post a whole lot of things that didn't work. Thanks for all of the information here, and I hope I can contribute in a positive way.
