You need an iron ring inside the magnets. This will intensify the field outside.

​@@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. kzread.info/dash/bejne/dIippdWhiJjIk5M.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.

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?

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?

Have you tried Axial motors?

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?

They alternate. For curved magnets, you must get 2 sets of them, half N inside, half N outside.

1:43 I think this is not the suitable head for this.

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.

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
