In Wikipedia it was mentioned Halbach arrays could be used to make this kind of bearing. Also a more advanced version of this in the future could effectively convert any wheeled electric vehicle into a levitating one. There are many active magnetic bearing companies and maybe you can have some inspiration for improvements in your design from their products.
I found a more basic version of that that uses a few rounded coil shaped magnets rather than having many different cube shapes, it pretty much operates on the same principle, though it isn't intended for rotation though suppose it could be. Mine is very primative, like its owner, lol. Cheers and salutes from a house owned by two rescued cats that let me live here rent free. Keep the rock alive!
@@amanchander7837 Greetings earthling, i too reside on your watery planet, at least for now anyhow. So, you have reached Level 41, and are requesting to reach Lever 42. Hmmm.. All i can tell you, is that he was using segmented collectives of cube shaped magnets, while the ones i used are ring shaped magnets, circular in a ring shape, rather than cubes with gaps. It's essentially doing the same chore as to create a suspension in mid air, though without those gaps causing spaces that would also create overlapping of magnetic fields. Mine is more primative. O shaped magnets instead of square shaped cubes. It's doing the same chore though, a floating bearing system preventing friction nor actually resting on anything other than that one plate at the end of the magnet array as is the same as what he is demonstrating there in that video. Mine is from a simple science kit involving levitation that relies on ring O shaped magnets held in place by a not so flexable straw, about the diameter of a pencil, with the magnets adjustably fixed onto the outer diameter of that. He fabricated his own version of that only using cube shaped magnets. If you have ring O shaped magnets instead of cubes, you could fix them onto a pencil to keep them aligned, plus with the endstop to prevent the pencil/straw from wanting to shift away. You can use any magnets to achieve this floating levitation in fact, theres no magic nor mystery to the principle. Hope that helps. Ok, you now owe me 1 working spaceship, though am willing to settle for 2 dollars! If you dont have the 2 dollars, it shall increase incrementally essentially doubling in price every 4 days with no present limitations imposed.

@@truetech4158 Thank you for your explaination. I really appreciate the way you have explained. Of course I owe you a space ship ( Only if CIA doesn't catch me :-P). I would like to levitate my supervisor first. LOl !!
@@truetech4158 "ring" shaped magnets? It sounds more like you are using *disc or *washer shaped magnets, no? As those have two opposite but equal planes in which they can repel one another through magnetic force, isn't that correct? An "O ring" shaped magnet, would have rounded edges, and therefore be less efficient at attracting or repelling similar shaped objects. Let me know that I'm correct, and I will only charge you pinged copper home brewery/distillery. If I have to find out another way, the cost will be much, much higher...muahahahah XD
I saw a similar bearing on some Polish channel without that wall. Instead of 2 single magnets on the axis, it probably had 2 pairs of magnets, so it was stable also in axial direction.
Question: if you used an aluminum plate on each side of the rotor, instead of the wall-and-point system, wouldn't the spinning magnets "see" a reflection of themselves (due to the eddy currents) and be forced to the center?
Do you think if you use two ring magnets at each end of the base plate and one ring magnet on each end of the axel then those will perforn better due to uniform distribution of the magnetic lines of forces? Coz in this model, there is a non-unoformity in the field due to separations in between each cube magnet which may cause friction.
You could get rid of that wall and put circular disc magnets on the ends flip it to the perpendicular way or up and down.... let the field of the ceramic disc magnet hold it up and the radial magnets keep it from falling over
why not use another four magnets at the both outer layer of the rotating axis and inner sides of the walls I mean there should be two walls. this will give much more stability to the axial direction and it will be more frictionless I think. but what do I know!!
I have a question if we put this axe in coper coil did we gain electric current? The second question is if we put solar panel on this axe and we will have rotation from Sun did elecric current might be good?
How much weight can be suspended this way in the real world of mechanical engineering? Could the rotor in a flywheel energy storage module, weighing 1,000 kg, be suspended by passive permanent magnets, if they were powerful enough? I know this can be done with electromagnets, but then you have parasitic energy loss, in the power supplying the magnets.
Use magnetic bearings and floating shaft turn into floating shaft alternator. Similar to magnetic bearings raise a wall of the same kind of magnets along the upper outer sides of magnetic bearings. To stabilize the shafts in location without needing the wall to keep in place also build magnetic bearings all the way around the shaft. Now attach this to a vehicle or portable generators. Add Eddy current coils around magnetic bearings. Now you have a generator that last for many years without maintenance.
Commercial magnetic bearings usually have an automatic control system for position. They can generate stronger levitation forces and allow you to adjust their performance.
Granted the commercially available bearings might have to be downsized quite a bit in order for them to find their way into automotive applications. Not quite so much for trucks and buses.
It's very difficult to realize this technology in automotive applications. I think it would be very expensive, exactly because of the technology. There actually was a company who developed electromagnetic suspensions for cars, but failed in the marketing aspect of their product. I forgot the name of the company, but you'd definitely find something if you look it up. It was much better performing than regular car suspensions, but very expensive...
Yeah, I don't know if it actually works or not, but I would expect that you could replace that metal contactor tip with a magnet with a pole facing straight out, and replace the wall with the same pole pointed at it. Do the same arrangement on the opposite end of the axle as well to give it stability while levitated. I can't say I know enough about magnets to say if the extra 4 magnets would disturb the balance in ways I don't expect. Although I imagine if you just made a really long axle that was also very light you could separate all the parts magnetic fields from each other with distance, and then test them interacting less with each other.
@@ldobehardcore Earnshaw theorem says it is impossible to have static equilibrium, but you can use magnets and diamagnetic materials to constrain the movement instead, making it truly frictionless.
Oh what if we use it with second wall to eliminate axe movement and we put magnes around the rod and surround them with copper coils and use stirling engine to move rod and we have got electric generator without friction losses😉
It would seem you are trying to suggest that using extra magnets at the ends of the linear bearing apparatus would replace the function of the fixed wall at the end of the apparatus, to help prevent the levitated item from sailing off its fixed status. Entirely possible. Keep on thinking about field attenuations, how overlapping can be regulated, adjusted even at high speed. #inSCIENCEwetrust The #DigitalLifeguardProject -_-
@@truetech4158 I am asking you to put the existing magnets at an angle so that those magnets will make the rotor levitate and stop the axial movement as well. No extra magnets required.
@@amanchander7837 You can try that, though depending on the diameter of the edges of the magnet, it may or may not go as planned. The overlapping of fields are not flat enough, you would want to shape fields with additional magnetic fields, or as mentioned, require magnets beyond the typical diameter. Perhaps examinations experimenting with variant hallbach and or chander arrays would prove interesting. ua-cam.com/video/eyCEexG9xjw/v-deo.html
When we try to stabilize one direction with permanent magnets, they create unstable forces in the other directions. In case we want to achieve full magnetic levitation, we need to use other techniques, like automatically controlled electromagnets.
it seems that Active Magnetic Bearing (AMB), a topic that was established in two last decades contradicts your theorem. Here is a quote from a scientific paper: _Active magnetic bearing (AMB) is a magnetic actuator. In the past two decades, AMB has been gradually adopted as a non-contact, lubrication-free, and levitation-efficient device in various industrial applications. Owing to its merits, such as the capability to regulate spindle dynamics, AMB has become a potential element for high-speed rotating machinery, e.g., milling machines [1,2,3], gas turbines [4,5], turbo-molecular pumps [6], and so on._ There is no physical contact in AMB
becouse u made it with number of magnes and not single round magnet, u will get a slowdown effect as those magnets meet each other. go and replace it with one big single round magnet in the chaft
Peace be upon you. Question if possible. Are there practical applications for the topic that are already applied? If any, please give me examples of that? Thank you
There are already several practical applications for commercial magnetic bearings. For example, high speed rotating machines, blood pumps for life support systems and water pumps for high purity chemical processes.
these look pretty , but in reality , the load they can carry is way too small . to replace a simple bearing with somewhat minimum load , you`ll need a lot of magnets to lift a 2 kg shaft , that is carrying a 2kw load of power and torque , this "passive " magnetic system will collapse on it self like if there are no magnets at all . i`m saying this because i`v done it before , the technical solution is active magnetic bearings , but there is a small problem to that .. they are expensive ... i mean , NASA expensive . if your shaft and load are heavy . stick to regular bearings .. the cost effectiveness factor in the majority of magnetic drive systems , magnetic bearings , couplings , etc , does not exist

What if you use opposing magnetic push to do what the wall does
Finally you can make a silent hamster wheel.

Super explantation .

You just need magnets at the ends as well to give it full non contact bearing, its used already in one of the stark motors
Exactly my thoughts
Thats exactly how mine works
Why did it cut when he placed it on its axle? Makes no sense
Hi...can we make something a small project like this active magnetic bearing ?
Hi Would it please be possible to share the CAD files for this experiment as I would like to make one too ??
