not a dremel. this is a illegal china clone used to be sold as demel no 'r' also has china safety label not UL like true made in USA Dremel. other parts also not same. never had this issue with any Dremel product as they are built very well using great materials and engineering. and zero metric parts all SAE

수위치켜는걸 어떻게 만들면 스위치가 켜지고 어떻게 만들면 스위치가 꺼지는법 만들때 스위치 안쪽에 무슨선이 어텋게 연결해야 되는지 알려 주셔야만 한국인기가 많으실거 같습니다

앞으로도 더 많은 영상 해주셨으면 좋겠습니다 한국에 인기가 많으실거 같습니다

와우 이채널 너무좋습니다 다른채널은 만드는 과정이 영어로 햇깔리게 만들어서 힘들었지만 압으로 시간될때 종종 보겠습니다 영상 감사합니다

Maybe adding carbon heat sinks you can draw the heat away also so the magnets never get too hot also!

Why didn't you just use an aluminum disc as the brake rotor and put some magnets arround it? Using an eddy current brake should be way easier than this and would solve the problems you went all out for to solve 😅

Good to produce free energy generators

Like playing with an atomic bomb, wild, small or big, the power is the same, what can stop it without energy

How about using this as a replacement for a bike chain and gears, kinda like this but without the chain? kzbin.info/www/bejne/epiboImIadBoes0

Good job. Can you tell me, is it rolling backwards due to the weight and it's gravity? Or stops at it's position where it is stopped. ?

Would be better if you measered &displayed power consumption of the motor itself in real time

THANKS A BUNCH. The shaft lock on my new Dremel failed during its second use! Have bought over half-doxen Dremels over the years... 1st time this has happened!

iranian ?

“No torque” is conveniently missing from the title

Bravo!

This could be great for split AC. Evaporator noise are from the AC turbine

If you add a variable-current stator plate in between, you could use it for infinitely-variable gear ratios. And the other thing is, if this is used as an electromagnetic coupling, there would be no need for a hydraulic torque converter to decouple the driveline when the vehicle comes to a stop. And if further modifications are added in, it could also have an electromagnetic clutch to connect the input and output together using friction material.

let's simulate reality in case we break it....

real G for life!

No contact No wear No lube And no torque

accent is horrible, video unusable.

Love it xan you make more about laser

An attempt to productize a magnetic clutch/transfer was made by MagnaDrive back in about 2000. All of this looks familiar and they had some very good systems for misaligned shafts, vibration reduction, gearing, etc. Great looking aluminum housings and led by a former Boeing CEO. But heat dissipation, reliability, and lack of performance along with decreasing capability over time led to its demise. How do I know this? I was an investor and lost a lot of money in what appeared to be a promising technology. So, as much as I like to see someone showing the journey, I know pretty much where this effort ends. The heating is due less to friction than it is to eddy currents caused by the rotating magnetic fields. Keep experimenting, but it might be useful to see what the state of the art is before engaging.

I suggest getting some stronger magnets and also print out a fastening harness to hold the magnets in place (1mm border should do) and print a thinner centerline insert to get them closer. Your effeciency should increase substantially from that, and the safety should also be much better.

No wear is a big claim for those who don't know how magnets lose magnetism over time... But there's also tools to remagnify... So still a neat idea that's possibly useful

That is wild! To make creating all of those tiny plates *MUCH* easier, I would 1. Spray insulating epoxy (or w/e) on both sides of a metal plate. 2. Clamp the plate to a CNC mill on a sacrificial sheet of MDF. 3. Drill some of the holes for mounting, then screw the plate down firmly. 4. Drill the rest of the holes. 5. Cut the pieces out, leaving tabs at each crossing point so the pieces stay in place. 6. Break the plate apart, stack the pieces on a bolt & nut--to hold them firmly aligned--and sand the edges smooth 7. *_PROFIT!!!_* Cheers!

clever dude alert !!!!!...geezus

No one talks about it, because this particular design is from Russia. And we all know that in Russia vodka, bears, balalaika can't invent anything there.

Put a load on it.

I've just watched about 4 or 5 of these videos i want to make one myself I understand the magnet placement but I dont understand if the object in. The planet gear position is supposed to be magnetic or not just to block it

Another problem with magnetic gears is that heat degrades the magnets over time. It would be better to just transfer the energy digitally to another motor instead of using many gears of magnets.

One guy built a bike with magnetic gears, and it was not practical at all. Had very little torque, the gear heated up easily, and was just overall a PITA to ride that bike.

no lo lubricaste ...

Is it fast? I will use it to make DIY Dremel

Nice research video🎉❤, can you explain what is the point making a magnetic gearbox instead of cutting conventional gears?

My piston was made of plastic and broke

Meine Fresse, so langweilig war mir noch nie.

Wow that's one unique voice and i just can't understand what the hell you are saying. No shade or insults intended just letting you know 🤷

👍👏

Hello stl?

The general idea is good and I am not expert but some points are against what you did there. For instance, you have replaced a 4-cell 4.8v battery with one 3.6v battery hence you totally lost some significant rpm there. Should have used the same 4-cell set, only avoiding Ni-CD batteries and replacing them with the very similar Ni-Mh The removal of screw fixing place.. big mistake! These are made for a sturdy build especially that the motor does more than it can using the planetary gear system. The whole gluing and grinding part to place the charging board was seriously messy... Thanks for the video, and I am just writing my thoughts should they seem to be beneficial..

If I grew up in a house with good security and money, I would probably have a lot more experience with this. I can’t afford the materials or education because this system has never really been fair from the beginning.

Don’t forget the modal interaction of magneto reluctance, and capacitive deractance you also have to remember the prefamulated amulite casing grammeters and the fact that there are specialized applications for something like this

Would there be less friction with bearings on all gears? I guess the most friction comes from in between the gears. And that is hard to do something about.. maybe less gears with bigger ratio as you mention in the comments? Fun video to watch 😀

Increase the center distance (a little) and you will be happy. It will be interesting to know how much the noise changes...
