your link to super strong magnet which is bangood.com does not have the curved magnets that you used. anyway, how did you bend them to the curve of your specs?
@@Echo3_ The iron ring goes inside the magnets (against the inside poles). Magnetic flux forms closed paths. The more iron you have in that path, the higher the flux density. (Motor & generator performance is proportional to the SQUARE of flux density). The magnet is "flux pump", and the structure around it "flux plumbing". If you have a restriction anywhere in the plumbing loop, the flow (flux) is reduced. The airgap between the rotor and stator is unavoidable, but all others can be eliminated. For a cylinder construction, the axial length is constant. So the radial thickness sets the cross-section for the flux. Since flux capacity in iron is about double that in magnets, the minimum cross-section of the iron path should be at least 1/2 that of the magnet. For a pole structure where the flux divides in 2, the radial thickness of the iron cylinder the magnets are mounted on should be at least 1/4th the width of the pole. The iron behind the magnets (and that everywhere else) should be annealed AFTER MACHINING. Torching it to red heat and air cooling in still air should be enough. www.controleng.com/articles/understanding-permanent-magnet-motors/ In the illustrations, the purple (left) & light gray (right) is the iron center in the rotors For your construction, the "spool" piece should be either all steel, or a steel ring (radial thickness > pole width/4) over an aluminum center. The spool should not have any significant sides. These shunt off some of the flux from the magnet's edges. Make the flanges only 30 mils high. That way, you still get magnet centering, without shunting off significant flux. Your magnets are "packed tight". Flux from the edge of one magnet loops into the next one without looping through the stator coils. Most efficient use of the magnet is where there is gap 1/4th the pole width between magnets. You don't show the stator construction. The reason coils are set in slots is again, to reduce the air gap. This applies for slow-speed machines. For high-speed machines, the losses in the iron teeth get high, so a distributed, larger, airgap is better. Iron in the stator must be laminated. Problem is, unless you have a stamping factory at your disposal, fabricating slotted laminations is virtually impossible. It is better to steal stator iron from old small induction motor. For high-speed machine, another way to build is to have 2 iron disks with teardrop magnets, and the stator between, like a stack of pancakes. ruclips.net/video/BTuCshX5bc0/видео.html You make 2 iron disks, and face these with magnets. Between is a thick circuit board with coils encapsulated inside it. Because all the iron parts are stationary relative to the magnetic flux, the iron eddy-current and hysteresis losses are reduced to insignificance. The flux density is lower than in slotted motor/generator, but that is made up by the increased speed (motor/generator performance is also proportional to the square of speed). If you run this rotor fast, don't rely on glue to hold the magnets on! Magnets are machanically weak. The plating will peel off. Machine a thin (0.020 inch thick) ring that slips over the magnets to bear the centrifugal force. It will have minimal effect on the flux because of its thinness.
Lol take apart some old xbox controllers and use the motors from in there, connect them in just the right way with some batteries and BAM, you got a lathe, dremel, drill, fan, anything else that spins
In an alternator, Magnetic rotor is rotated between 2 copper sheet, will it produce an AC which can be used in household or Will the the copper rotate due to rotating magnetic field or be stationary? Is it an alternator or AC Motor?
so the permanent magnets are opposite to each other with N-S pole,am I right?can you use halbach array to strengthen the mag-field,in order to somehow improve the efficiency?
I don't trust the way it has been built. At high rotation speeds, used as a motor the magnets can dislodge and come apart with drastic results. I would add a tight fit ring straps on each end to hold the magnets firmly in place, straps similar to wine barrels that hold the staves, or oak wool planks.
@@TableTennisVR-Indonesiathat is incorrect. The magnet is almost always attached to the rotor. It just happens that sometimes the rotor is outside and the stator is inside. attaching magnets to a inside rotor is a very common practice
Okey that's it... Honey, sell EVERYTHING! Sell the bicycles, our silverspoons, the sofa, lawn-mover, your parents... We NEED industrial machines! 😖 No, wait... 🤔 Keep the sofa! I love that one! 😊
И так. Он берет стопку магнитов в которых верх один полюс, а низ - другой. Затем клеит их бок о бок. Пишет маркером на верхних сторонах (полюсы одинаковых знаков) разные полюса. Это просто п@здец. Я еще не видел, чтоб маркером можно было менять полюса магнитов на нужные полюса. Жесть.
YOU HAFT TO HAVE NORTH AND SOUTH POLES TO MAKE THAT WORK YOU HAVE THEM ALL THE SAME AND YOUR ROTOR WILL SPIN ON THAT SHAFT IT'S TO LOOSE AND THE BARING FIT IS NOT GOOD EITHER.. "CLICK BAIT"
How about the link is for block rectangular magnet and he is using curved magnets. And since he is can't speak, nor mentions it, can not tell if all of his magnets poles are alike facing out. And if his rotor is aluminum or some other shit. And how perfectly he had the specs to make the magnet's curved fit the rotor surface and just the right number of the magnets for it. People are just rude show offs, feeding the other just enough but not simple details of the whole knowledge. Rude as fuck

You need an iron ring inside the magnets. This will intensify the field outside.
do you have a link for this I get what you mean but not sure where to put it.

Is it possible too speak too you for a bit off advice...cheers
Is it reverse polarity magnet, side by side?
I have enjoyed your projects for years, but can you do one on how to make a lathe?
Vraiment merci beaucoup pour tout!!!.
How the heavy magnetting work?
Aaah... the benefits of having a lathe machine. 🤔😌🙁😓

Are the magnets placed N,S,N,S or are all magnets facing N, or All facing S?
They alternate. For curved magnets, you must get 2 sets of them, half N inside, half N outside.
Aluminium is not good for dc motors it reduces the performance RPM of the motor
Truth
so the permanent magnets are opposite to each other with N-S pole,am I right?can you use halbach array to strengthen the mag-field,in order to somehow improve the efficiency?
No such thing as a permanent magnet.
I Will be right here waiting next project😉😁
Yeap! That equipment is expensive... 😗
Thanks for your help of expanding our awareness on this curious things
Have you tried Axial motors?
Are you sure about that polarity?
Yes. He must to alternate the polarity of magnets, so I'm not sure how he did it, because magnets have polarity in concave and convex sides.
must be N, S, N, S....
Perfect for a AC motor
Awesome video. 👆👆👆🤘🤘🤘
You can take off more material per pass. Try .040 imperial with carbide insert on aluminum.025 on steel.
Muito bom! Parabéns!
Can you tell me how to buy some magnets

I would add a tight fit ring straps on each end to hold the magnets firmly in place, straps similar to wine barrels that hold the staves, or oak wool planks.
Also de glue of the shaft would break
Thats why we see bldc motor have the magnet attached to stator body, not on the rotor

Hello mate can I talk too you possibly for advice...thanks
it is a beautiful and most efficiency rotor
Very good , 👍👍👍
You have made my day
Can you try to make a video and spin this "rotor" ? Thanks
What size lathe machine did you buy and for how much and how long it took saving RUclips earnings?
What name this magnet🤔?
i need your helpful finding the video that follows this one on how you used the rotor

Hi man, the core is aluminiun?
Can it be plastic? or not?
Plastic is okay but hard nylon is even better. Aluminium and magnets don't mix well.
@@mickcarson8504 nice info brother
Your title spelling is wrong plz check it
roter = motor
No...the bit that rotates is called the ROTOR , the static coils is called the STATOR..
Muy excelente rotor pero hizo falta mirarlo funcionando
tell me the OP is a guitarist whitout telling me he is one
Please where can I download the fusion application
Bien video mi amigo
De que material es? Aluminio o acero?
Y la polaridad de los imanes? Que configuración tiene?
Sir pls send magnets shopping link

and where is copper wire?
In shop is bar magnet not curved magnet
You have to protect the magnets with a copper tube, those magnets are dangerous with the speed...! can you share the link for the magnets...?
You'll find all shaoes and types on banggood.com.
Don't use copper. Use THIN steel tube, 0.020" thick.
Good job
I love LATHE MACHINE
You are too amazing with Inventions Mr American Tech
fake
dude, your fail point is the glue!!! you've built an strong structure for your rotor and all this is suported by GLUE??
1:43 I think this is not the suitable head for this.

It is not a motor.
It is a rotor (the thing with 🧲 that spins,) not a motor.
