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.

[@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.

[@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 lack of magnets is probably the reason why this isn't going commercial yet

[@NMA_NoMoreAmmo]

It does not have practical or commercial value. Comparing with cheap belt and pulley system. Unless you stick Apple or Tesla logo on it and sell it as a unpractical novelty.

[@zaid.1271]

"no vibration" the whole thing vibrating.

[@Un4rm3dgames]

I wonder how cool it would look as an holographic clock Also same, it showed up here even though the video is 2 years old

[@neo-dyne322]

Well, let's make one:) I can do the transmission if you can provide the rest.

[@jeyarajshankar]

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

[@MichaelSHartman]

Interesting. Definitely, more expensive than machined gears. Rare earth magnets are not cheap. If electromagnets are used, there will be a continuous energy cost, and carbon footprint. How much load can it take? How robust are they if the teeth touch? How will extra weight affect them? What applications are these lightweight gears intended?

[@squeakybunny2776]

You could still use electromagnets for the purpose of making a really quiet machine. Would like to see this thing actually do something though to see if it works at all

[@tars_06]

You can use solar energy as energy source for the electricity of the electromagnets. And, you can make permanent magnets.

[@harshbarj]

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

[@mickeydangerez]

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

[@cjjuszczak]

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

[@guntherultraboltnovacrunch5248]

I could see something like this being very useful in something like... A clock.

[@Patrk38]

hows that useful?

[@honkhonk8009]

Maybe if you had it run in insanely high speeds, you could compensate for the torque maybe? But honestly idk wtf engineers gonna use it in lol

[@sacredsermon2027]

Physics has been innovative like never before...

[@AndroidFerret]

That looks amazing...Will there be a bicycle available with that soon ?

[@neo-dyne322]

Hi Android, yes , I hope, I got the gear but not the budget:)

[@AndroidFerret]

@@neo-dyne322 try selling it to BMW or another big company ...they make high quality bikes .. But be extremely careful ..

[@zakaroonetwork777]

Gates belt drive is better system.

[@JaakkoF]

@@zakaroonetwork777 What is the advantage of a belt drive compared to this magnetic gear system?

[@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.

[@kingunicron3863]

Machine from future. I hope john titor see this Grat job bro

[@quarterpie5338]

Wow, have you done calculations on the efficiency of energy transfer for these gears? I can already think of hundreds of ways to use these

[@neo-dyne322]

Hi QP, yes I have a chart with different values, if you have any applications then please let me know - [e-mail]

[@prashkd7684]

"without losses" - I doubt that

[@PutsOnSneakers]

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

[@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.

[@Jabulaya]

and what happens when the orientation of those magnets shift due to the magnetic flux?

[@scottsmith6932]

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

[@abaldons]

Ciao! May I ask how is the polarity on the magnets? I would be really interested. Did you write some paper on it?

[@neo-dyne322]

Hi Andrea, there are multiple poles, and the magnets levitate - will explain in more details after the patent application is approved.

[@changer1285]

Finally. I've been wondering when I'd see this sort of tech for like ten years. Seems like an obv way to use less lube

[@neo-dyne322]

Yes. Here’s one with sound: kzbin.info/www/bejne/m2LNgGqdl7ykjtk. Alloy units (kzbin.info/www/bejne/d6u9qKyga5pjh6s ) would do 160 - 1,200Nm as standard, exchange ratio up to the client. Lifetime 50 years, and every year you save oil, spare parts and gain some efficiency.

[@isuckharderthanlife5413]

Impractical. Permanent magnets lose their magnetic properties within weeks when fixed into a repelling configuration.

[@kjyhh]

It wasn't no noise, it was just muted.

[@neo-dyne322]

Yes, dogs barking outside. Took the sound off. Gears however are quiet, you just hear the drive unit like in this movie: kzbin.info/www/bejne/d6u9qKyga5pjh6s

[@jaysen472]

That is somehow the most beautiful thing I have ever seen, I mean besides some of the insta-girls I follow.

[@neo-dyne322]

Thanks man

[@dELTA13579111315]

simp

[@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.

[@dragonslayerornstein387]

THIS IS REVOLUTIONARY

[@neo-dyne322]

Thanks!

[@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!

[@indusgod12]

You are gonna change the world one day

[@neo-dyne322]

Thanks man

[@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.

[@pulsefel9210]

ok so gotta use this to work on a perpetual motion generator ive been working on. solving how to eliminate friction energy lose was a pain. i knew magnets would be the answer, but this is perfect!

[@harynian]

This is great technology with the future. I hope it will be common in many aplications.

[@neo-dyne322]

Thanks - already alloy units (kzbin.info/www/bejne/d6u9qKyga5pjh6s ) would do 160 - 1,200Nm as standard, exchange ratio up to the client. Lifetime 50 years, and every year you save oil, spare parts and gain some efficiency.

[@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 !

[@ryzenryne8747]

That's a new way to prevent the gear teeth from breaking down.

[@neo-dyne322]

[@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.

[@StarWarsTherapy]

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

[@GoodGuyMana]

Curious what load it’ll take before the gears start slipping

[@itburnswhenip]

Id love to buy some of those Magnets.. be a fun kit to play with

[@azlirameliasdasilva4662]

Em um mundo sem carga, tudo é maravilhas, vejamos isso se comporta com carga, peso, quando exceder o máximo magnético repulsivo fará as engrenagens se encontrarem e terá o atrito, já há muito a indústria tem acoplamento magnético mais eficazes, acoplamento em meios óleos e por aí vai... mas todo esse trabalho serve como ilustração educativa e abre a mente de alguns para futuras ideias...

[@PandaOnSkis]

I could see this being useful as a sort of shock absorbing gear

[@P4NCH1]

Cool. What about temperature?

[@neo-dyne322]

max 300C

[@jesusmarywillsaveyou]

Amazing. Would love to see real world applications, like in a clock (or watch), bicycle sprockets, chainsaws etc.

[@SusanAmberBruce]

Some awesome shit you got going on there, can be sure this will blossom as a way of doing gear stuff

[@tobywenman4769]

surely the eddy current losses are pretty large if you mount these near anything ferromagnetic?

[@kathyzed8870]

WOW, no noise, no friction, no wear, no heat,no resistance, Amazing

[@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.

[@vikassawant5715]

How much torque can be transferred ? negligible compare to normal gear

[@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..
