So do not attribute to Allah equals while you know [that there is nothing similar to Him]. ( 2:22 ) 🔵 And if you are in doubt about what We have sent down upon Our Servant [Muhammad], then produce a surah the like thereof and call upon your witnesses other than Allah, if you should be truthful. ( 2:23 ) 🔴 But if you do not - and you will never be able to - then fear the Fire, whose fuel is men and stones, prepared for the disbelievers.( 2:24 ) 🔵 And give good tidings to those who believe and do righteous deeds that they will have gardens [in Paradise] beneath which rivers flow. Whenever they are provided with a provision of fruit therefrom, they will say, "This is what we were provided with before." And it is given to them in likeness. And they will have therein purified spouses, and they will abide therein eternally. ( 2:25 ) ⚠️ Quran

I was always wondering how rotors or shafts are being protected from leaks. I never thought it would be this 'simple'. thank you

[@dtibor5903]

I worked in industrial enviroment and i never saw magnetic coupling. Usually they use rubber gaskets, they last very long time if installed correctly, and very reliable if replaced regularly.

[@court2379]

There are dozens of types of seals, orings, PTFE vee rings, sprung elastomers, leather, labyrinth seals (torturous path), solid carbon seals (very tight clearances at high temps), little pumping turbines that hold back the leakage, packing glands with various packing materials. Packing glands, orings and elastomers are most common. They are leaving out why magnetic couplings are not usually used. They slip, which means there is not positive control between each side (at least most of them, it would be possible to make one that only slips on over load). The slipping also means it is not very efficient losing a large amount of energy to heat. They are also extremely expensive. So they are only used in applications where the hazard due to a leak is extreme, or no other solution really works. Very caustic materials for instance. They have limited higher temperature use because the heat ruins the magnets, though maybe an electromagnet-eddy current design could be made to work at higher temps. These things all require custom engineering making them expensive. What seal is selected depends on many things. The speed of the shaft, it's material, the sealed fluid/material, the temperature, service intervals, the hazard of the sealed material, how it is to be serviced, cost, among other things. That covers the most common considerations.

[@Xenon-noneX]

Though it's still not so common. The method we saw in the beginning is still used on huge scale, doesn't cause any problem Though. Works even fine for high pressure reactors (Personal Experience).

Thank you for the video, I found out that investing is not for everybody, you just need a strong stomach too see your portfolio go down. It might be wiser for a novice to start with copy trading investing, but it is not easy. To invest in growth stocks it is another level, definitely you need to know what are you doing.

[@benjaminotto5711]

From my own point of view, you need to invest smartly if you need the good things of life. so far i've made over $255k in raw profits from just 6 months into the market from my diversified portfolio strategy and i believe anyone can do it you have the right strategy, mutual funds takes long time but investing smartly is the key for short term. Most of us tend to pay more attention to the shiniest position in the market to the cost of proper diversification.

[@sophiablakes]

This is a phenomenal advice for a new stock traders and investors who want that quick short term game, but don't see the light at the end of the tunnel.

[@benjaminotto5711]

My portfolio is very much diversified so it's not like i have a particular fund i invest in, plus i dont do that by myself. i follow the trades of Mrs Karen Gaye Gray. She is a popular broker you might have heard of. I can correctly say she's worth her salt as a financial advisor as her diversification skills are top notch, because i see that in her results as my portfolio grows by averages of 10 to 15% on a monthly basis, unlike i can say for my IRA which has just been trudging along, my portfolio just mirrors what she trades and not just on some particular industries of my choosing.

[@danielrichter465]

@@benjaminotto5711 By following her trades do you mean copying her trades? I have heard about copying trades

[@benjaminotto5711]

Yes, exactly. It's all programmatic and automated, plus it's relatively much easier to set up and connect my accounts than creating a financial plan and drafting investment strategies myself, my account just mirrors her trades in realtime.

Sometimes I feel dumb for not realizing that these types of connections existed; it's so simple!

[@observenotify8604]

Could be connected with reduction and multiplying gears, still working with the air gap and soft metal in between as a weak link to break in excessive overload.

[@darshanvaibhav9098]

Bro . I think this is one of the ultimate driving technology without connecting. Really interesting

[@Xantec]

the liquid Sodium cooled FBR at Dounreay, Scotland used Magnetic couplers on the Sodium cooling circuit

[@danser_theplayer01]

If you even played Scrap Mechanic you would probably find out a similar design. A piston or a suspension are both "ghost pieces" that have no collision, which means if you need a through shaft (a part that does not exist in that game) you would make such "magnetic coupler" connecting two shafts using a piston.

[@bekone]

I was thinking how cool will be something like this a month ago and now I see that it exists!

[@bayareapianist]

Electric motors are mostly act like a cylindrical decouplers. These days motors, specially dc ones have electronic control circuits which check the current and temperature. If anything looks unusual, they can shutdown the power.

Why would you need a magnetic coupling on a motor? It is already a magnetic coupler between the armature and field coils. If a motor is overloaded you handle that electronically.

[@sonipriyana9405]

If there are slip, eddy current will occurs..the shaft will get more heat.

[@jocksam6634]

I first noticed them in speedometers when I started taking things apart.

[@MegafAirCombats]

First! Thank you for the video, I've been wondering about magnetic couplers for a while now and always wondered how they can transfer torque. Edit: I wish it went a bit deeper into the types of magnetic couplers and compared them, there were only advantages and disadvantages on the axial magnetic coupler. What about the radial one? Are there electromagnetic couplers?

[@ahobimo732]

I've never seen an example of an electromagnetic coupler, but in theory there's no reason it couldn't be done. It might be a rather complicated and bulky coupling, but it's definitely possible. Just replace the permanent magnets with electromagnets. It's quite an interesting concept, actually. It would give you the ability to adjust the coupling force by adjusting the strength of the electromagnet. But of course the disadvantage is that the coupling would require constant current in order to function.

[@mayurdahiwale5907]

Science videos do not get enough views, and even YT's algorithm only pushes entertainment related stuff to people. It is now very hard to earn money through AdSense

[@makantahi3731]

interesting topics but it is made supeficially: i am thinking to use it on water pump on car as rpm/torque regulator and energy saver: as engines rpm rises, and water pump rpm rises and after some rpm pump makes cavitation and coolant flow makes too much resistance but no gain on cooling and it needs high power , so goal is to hold pump rpm on some 4000 even if engine rpm rises over 4000rpm, so in coupler must happen slipping because difference of rpm between input and output shaft of coupler and question is do i really save any energy or it goes into heat in coupler

[@TecSanento]

But wouldn’t it be easier or the motor be the coupler itself? So that the rotor is the mixer part itself, and the stator coils are the fixedly parts on the outsides :) b

[@ahobimo732]

That's a damned clever idea! It's probably already been done in certain applications. But of course creating and maintaining a custom engineered device like that would be VASTLY more expensive than using standard electric motors and other industrial parts. There are dozens of companies that sell industrial electric motors, couplings, etc., but very few who design custom devices like you described.
