Lego Magnetic Motion Transfer  

Old Honest Abe knew a thing or two

@@worldcomicsreview354 hmm

That man was Wisebert Wisenstein

If he was actualy wise he would have said lego and not legos

Nice question...

Depends if this is a technic set or a normal lego set…

I doubt the wind would break it if you made it stable enough

Matbe, but that would require some very talented lego builder to design it strong and wind-proof enough

@@NoNo-rj2hl why would that matter? Standard Lego is incredibly robust when implementing brackets into the build. Watch the bridge episode on the first American season of LEGO Masters.

A lot. Some pumps work this way. They are designed like this because they pump hazardous chemicals and this way you don't need a rotating seal around the shaft. No chance of leaks this way.

The only problem is that it likely has about 0 torque.

I can prove some insight here - I work with and maintain rotary vane pumps in a laboratory and a lot of our pumps are "magnetically coupled" pretty much in the way demonstrated here. How much torque can they transfer? A lot - those pumps usually run on fixed frequency AC motors with only two speed settings also called "on" and "off" Whats the advantage of this coupling? Little to no maintenance and the most important thing - waaaaay less chance of oil leaking. You can change the motor of a pump without draining a single drop of oil within 2 minutes.

@@minklmank not exactly those pumps are just permanent magnet motors, and generally dont need a heap of torque since there is little resistance when starting since centrifugal force is what moves the fluids which relies more on the motors speed which is also another reason they are good for pumps because if some foreign goes inside it, it can lock up the rotor and there is a less chance of damage

@@minklmank The fact you work on these pumps and yet don't realize how they actually work, is worrying. Inverse square law...

Thanks!

To me, it just sounds like a clutch

@@nefarioulyte9996 a clutch is a device to disengage and engage power. This could function as a clutch, but the fundamental device is called a halbach coupler and uses alternating polarity magnets to couple rotations without a physical connection. Seriously, it is fascinating and worth a google search

Thanks! Glad you like it 😊

I actually own a lego magnet piece somewhere in all of my stuff

They did - railway car connectors from at last one lego train set i had in the 80s

(not sure if its true) There were magnet pieces in old venator class star destroyer from star wars

I agree,they need to make a magnetic piece like a crane with power function,just like magnets crane used in junk yard

There was a whole line called Magnetrons

I’m telling.

Cool idea!

thats the same thing I was thinking too lol

Direct coupling of magnets like this is inefficient, but it's not too far removed from an electric motor. You'd be better off with a generator and motor set, in which case it's already known as a diesel-electric drive train used in diesel locomotives and heavy vehicles. It's also the basis for some Hybrid EVs which may or may not use diesel, but that's not the important part. Doing it this way, rather than using shafts, allows for much more freedom in where you put the power unit, and where the driven wheels are, and how those wheels can move. It also allows for exotic, power units, such as turbines without needing a complex gearbox, or a mixture of power units that can all feed the same motor.

@@kal9001 so it’s more efficient to effectively just use the engine as a generator to power and electric motor? What about using magnets in combination with a regular torque converter? Could it maybe help the input and output sync better?

@@kal9001 That's a completely different thing. Do you know what a torque converter is?

Thank you!

you do relise that the torque output of that is basicly nothing? "rotational energy" you mean rpm? cause if you jam it to 1000rpm quickly then it wont work if you slowly get it up to speed then it works but it still aint got shoot for torque

@@djaydeved it'll probably work when kranking it up instantly (up to a certain rpm at least deoending on how strong the magnets are) but it would "drag" in the beginning.

Wow, thanks

It's way less efficient... Also it's irregular

That would be a horrible idea. The amount of energy lost between each magnet will follow the inverse square law..

Thanks!

Happy for the both of you! 😉

Yea

I saw that vid

@@mauntaxthelegend3188 you don’t need the apostrophe for pronouns because ownership is assumed

@@pieppy6058 right xd

Thank you for the nice suggestion!

My theory is that this works like a synchronous motor, so the RPM would be the same but there would be some phase difference, depending on torque. Too much torque and they de-synchronize, at which point significantly less power would be transmitted as the driving wheel would spend (worst case) half the time accelerating and half the time decelerating the driven wheel.

There's zero difference.

same rpm by the looks of the slomo but torque transferred is only a fraction of the motor

Thanks!

Glad you like it!

Thanks!

Try bricklink com plz

Sure 😊

As awesome as it sounds, there aren't a lot of applications for it because anything would create a load. If it was for circulating air or something that can work.

@@ethanoldenburg6645 lol there are a LOT of applications for this and it's used in reallife. Starting with motors, pumps etc.

no, the magnets will slip.

Neodymium

@@DrEngine I saw neodym magnets 4x2mm, they should fit the LEGO holes So you are using bigger ones? I heard they are fragile, it that true at this scale, or are they small and tough enough?

@@jakubpollak2067 I used 8*3, and yes, they're very fragile, broke 3 or 4

@@DrEngine Thanks for feedback I'm planning on making a plastic capsule around them with 3D printer, simple hollow cylinder and put them in just before printer will make top to enclose them Hopefully it will secure them Also the "capsule" should have LEGO holes and pins Are you interested?

@@DrEngine How? They're IRON, and shouldn't be fragile at all!

💯
