If you had one of these attached to a tesla turbine to get the speed up, would the torque issue cancel out if you were trying to use halbach gears as an air pressure nozzle, ie, trying to recycle some of the lost air coming out of the tesla coil back into the compressor??
Here are the relations: q = pₗ + pₕ Gear Ratio = -pₗ/pₕ ... if the modulator is the fixed member (not the case for this 3d printed example) Gear Ratio = 1 + pₗ/pₕ = q/pₕ ... if the outer ring is fixed where q is the number of modulator pieces (set screws on the drive rotor in this example) and pₗ and pₕ are the number of pole pairs on the low and high speed rotors respectively. This paper from NASA is a great resource: www1.grc.nasa.gov/wp-content/uploads/2018EATS-Magnetic-Gear-Scheidler-6.2018-4988.pdf
How do you control which side will be stronger? On your outer ring halbach array points inwards. But in your inner ring halbach array needs to point outwards. What is the difference in arrangement?
Lets assume the arrows are pointing towards north: This Halbach array would make the top side of the array stronger: →↑←↓→↑←↓→↑←↓, while this array would make the bottom side of the array stronger: →↓←↑→↓←↑→↓←↑ So the "sideways" norths point to the magnet whos north will be on the stronger side, if that makes sense.
This Is very new for me, but i'm wondering, Is there a way to make a gear magnetic train? I mean, to increase x100 the turns on 4 magnetic gears combined?
Great, exactly what we need to drive the schauberger repulsine with normal speed motors :) useless for the old systems but very useful for new sighting views :) thx a lot :)
Have you tried with square magnets rather than round ones?
Have you experimented with the screw size?
That is really cool, I'm printing one now . gonna have a bit of fun experimenting

What is the relation between the number of magnets on the rotor, stator and output ring?
There was a study conducted by Atallah et. al. Hope this will help to clarify relations for you. DOI: 10.1049/ip-epa:20040224
Here are the relations:
q = pₗ + pₕ
Gear Ratio = -pₗ/pₕ ... if the modulator is the fixed member (not the case for this 3d printed example)
Gear Ratio = 1 + pₗ/pₕ = q/pₕ ... if the outer ring is fixed
where q is the number of modulator pieces (set screws on the drive rotor in this example) and pₗ and pₕ are the number of pole pairs on the low and high speed rotors respectively.

This video explains the relation really well (in the last minutes): ua-cam.com/video/YuZ0W4TugG4/v-deo.html
Great work :D now I want to print my own
Thanks for the great explanation.
Thanks for watching!
Could this be used to make a much quieter hand crank generator for example?
Definitely! magnetic gears are sometimes used for flywheels or wind turbines

@@povsky1 Thanks for the reply. So it seems that side that has concentrated (converging) norths is the strong side.

thank you for ur awesome video! !
btw which type of 3D printer do u use? thx!
I use a bamboo skewer and super glue to make my magnet guide. Just blunt the tip
Nice project!
Excuse me but as I see it, the 2 axle are physically connected
if you want a multi-pole magnetized ring instead assemly, I can help
Wow this guy rocks
Stop the vocal fry
