As many others have suggested there are energy losses associated to the magnetic fields and I guess there will be a limitation on the max load (or torque) the gear can take before the magnets get in contact and possibly suffer damage. Anyway it's a great idea and surely a nice improvement for many machines/systems.

[@abnormaalz]

While this is very interesting, I think there's a few things that should be noted: - It is not entirely friction-less, magnetic fields do bring friction with them. - I think there are definitely vibrations transmitted. - When the system is overloaded, damage can definitely be done by the gears touching. That's why "normal" gears are made to have contact at all times, to minimize damage from wobble. - When overloaded, the system isn't quite as effective and efficient. Having said that, I think this is a very cool concept! I bet this way of gearing can be advantageous over normal gearing in certain applications.

Becouse magnet material will break if you put any torque on it.

[@Modna89]

I'm assuming difficult to make high-torque applications. Additionally allows for harmonic frequencies in the "bouncing" between the gears. Also I want to know the resistive losses from the induced currents in the magnets. This isn't so say this isn't super cool - just I 'd need a LOT more information before it could seem viable

[@Kirillissimus]

I guess they are not very common for many reasons including lowered efficiency due to the currents induced by the magnets, narrowband vibrations due to the magnetic interaction nonlinearity, very low mechanical shock resistance and much higher price of such a big amount of magnets and their holders compared to just a machined piece of metal. And the only real benifits are reduced total noise, lower acceptable manufacturing tolerances and largely reduced lubrication requirements. For most applications it is just not worth it I guess.

[@TOCZEKX]

moreover spinigi it near metal enclosures will heat or even melt them

[@user-dj1hy6zc6q]

"No noise" and high efficiency when there is no load. Cool, but what about when using the gears to do something?

[@Malidictus]

That's what I was thinking, as well. There's only so much load you can put on that setup before the magnets bottom out against each other. It would obviously depend on the strength of the magnets, but I'd be surprised if the bottom-out load is even close to a mechanical link.

[@1stPrinciples455]

Also if the uneven roads make the wheel and gears collide

[@outputcoupler7819]

Losses should scale with load, but exactly what that relationship looks like, or even a rough approximation of worst case losses is a mystery to me. Could be not quite linear, could be worse than linear. Worst case losses could be much worse than gears, or much better. I really don't know here. What I expect to happen is that as the load increases, the gears that are meshing move closer and closer together, until they touch when the magnetic force is completely overcome. Assuming RPM remains constant, this means you're moving one magnetic field through another at both increasing speed and distance, which both will work to amplify the eddy currents inside the magnets, which should be the primary source of losses. That said, I suspect this design retains high efficiency with a fairly wide range of loads. Or at least I think it can be made to do so, that's probably just an engineering problem as you can size the magnets up significantly to reduce the "squishiness" of the teeth and thus the losses. Though I believe this would increase your baseline losses, so there's some nontrivial math to optimize this. Also, it's definitely worth considering that spur gears also have worse efficiency at high load. Which one scales worse? Hell if I know. The real problem from where I'm standing is durability when load ratings are exceeded. Like if you used this for a lathe and then crashed it. This thing ain't gonna slip, those teeth are going to bottom out and it's going to fail catastrophically with magnets flying everywhere. So for many applications this needs to be paired with a clutch of some kind that can slip and protect the gearbox in an overload. This is also true of a lot of geared designs, but this being made of plastic makes it a hell of a lot worse at withstanding such events. But to throw some rain on the parade, this is definitely not revolutionary and won't take the world by storm. Magnetic gears have been a thing for more than a century, the first patent I could find was filed in 1901. Magnetic gears are interesting and have some advantages, but there's a reason they haven't seen wide adoption, and it ain't tradition. Spur gears are already extremely efficient (98% or so?) and require very little maintenance. Hell, even a worn out V-belt hits something like 93% efficiency (98% properly tensioned), are much less likely to fail in an overload, and when they do fail anybody with a wrench can replace them in minutes with a part that costs a few bucks. At the end of the day, reliability matters way, way more than bumping your power transmission efficiency from 98% to 99%. And it's really, really hard to beat the reliability of a dumb chunk of metal like a spur gear.

No depending on the torque load its more likely to damage the gears. The teeth are not properly meshed and don't have good bearing angles they would wear terribly if they mechanically meshed. The gears also can't be made out of ferromagnetic materials so they would either have to be made of plastic like this and be weak or be made out of exotic expensive materials like titanium.

[@neo-dyne322]

Hi Cosmin, this is a good question. Usually the term "backlash" is associated with mechanical cogs. These magnetic cogs work in levitation and lock in the air. This is a demo unit to help to see better, however commercial units are tighter, more compact. Here's a demo movie, a try to create backlash: kzbin.info/www/bejne/p166XnSYfJmFq9k

@@neo-dyne322 you done any prototypes that are more like a Helical gear?

[@mickeydangerez]

COOL IDEA! The magnets at that size probably has a low load capability but this scales up well well.

[@Kresnove]

Do you have any proof that this is even as efficient as gears? Gears are very efficient as it is, and I can imagine this would produce large eddy currents in the magnets which would suck alot of the power away.

[@harshbarj]

"All power is transmitted without loss" Impossible. There is always loss in a system.

I can see massive uses for this. Thank you for this innovation. Let's see how to bring this to the railway industry.

is this video without audio ? why the hell would yo claim "no noise" when there's no audio at all on the video ??

[@gregmark1688]

No friction ... No noise... No torque!! Truly amazing what the human mind can do.

[@pwnmeisterage]

There must always be some gear-to-gear power loss. A magnetic interface might (or might not) be more efficient than a mechanical interface (even in a vacuum, even spinning on a magnetic bearing, etc), but it cannot ever be lossless. Rotating magnetic fields turn power into electrical fields, along with electrical losses vs induction effects, imperfect insulators, etc. Manufacturing costs for magnetically-oriented parts would be higher than for ordinary metal parts. Sudden starts or stops would cause the gears to collide possibly grind, and this might be catastrophic under load.

True, because some of that energy is lost in other forms of energy such as pushing the air thats around the contraption, energy into heat transferal, and so on. I mean I THE LORD teach humans this but humans still want to come up with youtube videos claiming BS lmao

It is creating it's own field. Magnetic FLUX should have no effect. Helicopters have Flux valves for navigation., It has no effect.

[@keatonhatch6213]

Mechanical loss at the gears isn’t *because* *of* *the* gears, it’s from *turning* the gears. It doesn’t matter how the gears work or are arranged(unless they’re slipping) it’s not going to reduce or increase loss.

[@Teth47]

You're going to lose some to eddy currents, which will become more and more of a problem at higher speeds, but this is very nice as a practically zero-maintenance solution and you have the added benefit of no shear losses from the lubricant.

[@someguy5035]

The magnets will lose their power over time.

[@circuitdotlt]

there will be eddy losses, that may be significant at high rpm. Lubrication is still needed for overpowering, unless you will couple this with a slip clutch.

[@trinsit]

There will be friction on the bearings, but I wonder how much of a drop in friction there actually is. It looks fantastic! Love the idea, but wonder how powerful it actually is and how long it could run before the magnets need maintenance as they lose strength over time.

[@neo-dyne322]

Yes, bearings have friction. Magnets will last 50 years. Alloy units (kzbin.info/www/bejne/d6u9qKyga5pjh6s ) would do 160 - 1,200Nm as standard, exchange ratio up to the client.

[@isuckharderthanlife5413]

Permanent magnets lose their magnetic properties within weeks when fixed into a repelling configuration. Hard fact, nice toy though..

[@StarWarsTherapy]

This is a very clever solution to gear friction. What is the measured back emf load?

[@biveksharma4413]

This is a game changer. Using magnets in gears might just prove to be more efficient and may dramatically decrease the power consumption and reduce repair costs in the long run. Downside? Higher manufacturing costs leading to increased price of the equipment in which it is used also may render unusable in products using metals gears, especially like high tensile materials containing ferromagnetic substances like steel due to its self magnetization properties of said materials. That means, it could be unusable in automobiles, in which these systems are most required as they consume fossil fuels (Exception: Electric Vehicles.) This technology is a practically usable one if used in the conjunction with diamagnetic or non magnetic materials or until a non-magnetic and cheap substitute of steel gears are available. Still, it is an ingenious invention and has the potential to be big.

[@DheerajSharma-ol3go]

It is crazy how you have replied to every individual to clarify losses ! but an interesting thing this is ! am sure this would be better way to propel a wheel !

[@ToaLewa6]

claims aside, this feels like a huge step forward in making large-scale gears last longer, even if it's not exactly cheaper up front.

[@n3lis94]

This would be able to transmit a tiny fraction of the torque that classic steel gears would be able to for the same building space, so no, I really don't think so. Only for very specific applications perhaps.

Good idea..There is no friction but isnt there opposite pressure on each magnet before they come close to eachother ..

[@xXblinnyboyXx]

I get how he said, “no losses”, but it’s likely damn close. Not the best choice of words, but give the dude a break. It’s a idea/concept. Some thrive, some are just cool/impractical. Also, I think a really interesting characteristic is it’s ability to cushion impacts. Imagine this used in a racecar transmission. On heavy launches or shifts it could help reduce the internal shear and normal stress on parts. Good work brother! Keep perfecting!

[@klydevillalord2405]

Woahhhhh. That's cool. But I'm just wondering also correct me if I'm wrong but that the gears are/can be only operational in low forces or relatively low speeds. Again correct me if I'm wrong but from what I know is that there is just some amount of force or speed that the gears start to touch with each other. How much force or speed is its max because if it can replace conventional gears then that should be the new gear standard????? I guess if you scale that up it can support higher loads but I'm just wondering what's its max force or speed that it can handle given that you'll use the right materials and manufacturing techniques. As I can see the containers of the magnets are just 3D printed and those typically are not strong. I can really see some potential in the concept. I just don't know how feasible it is????? That would be nice tho if it can replace the traditional gears because you wouldn't need oils or any to maybe cool or reduce the friction. That would be nice. That would be the new standard for gears and much more applications for that.

[@Solizeus]

Cool gears, but then not only the resistance of the material but the power of the magnets are going to need to compensate for the force that is going to be exerted and it is going to need a power supply because the magnets will lose power eventually right? So... that is cool if you care about friction to that point, but where to apply it? Also, the rotor already makes more noise than the friction between the gear and the chain, so it isn't really less noise i think, but it is cool, maybe there is a specific application to it
