I had this concept of using a single diametrically magnetized cone D50 neo as a bearing. I imagine someone has already tried this....

Now, here's the thing... the diagram as shown, most likely will not work... because the whole half of the cone wants to lay on it's side, it's not magnetized top half/bottom half BUT...

If in the diagram, you replace the part labeled "Iron Disc" with a sizeable Steel Shot (sphere) - the physical weight of the rotor may do the trick, given the Neo might not be able to "pull it up", if you follow my thinking. Alternatively a spherical Neo might be used, with a spherical steel shot, too.

this is a good idea but hard to do large scale.. i did this before using a neo sphere and a sewing needle where the needle hung straight down and the sphere dangled from the tip, with a rotor shaft attached right under the sphere. worked really good when it was all balanced.

So basically the rotor is hanging below the N50 neo, wont it wobble itself till it fly off if its just abit unbalanced?

Balance would be an issue, but.. it is for any magnetic bearing, no?

TJ-quote-wont it wobble itself till it fly off if its just abit unbalanced?
I see nothing wrong with a rotor flying off at 5000rpm and go zipping around the workshop.This is when you would see some real free energy in the way of the bloke going from 0 to 60 in a split second heading for the door while running on pure adrenaline.
Kcarring-this is indeed an interesting concept.I have a window motor that has a magneticly suspendid rotor shaft and it run's quite well,but dose jump out of the magnets every now and then lol.
What about a cone within a cone that were magnetised through the hight rather than diametricly?

why not mount this on its side and have a second neo bearing? it may hand slightly off centre but that will give it stabilization because the bottom is heavier than the top - like a hanging object is
