Working Attraction Magnet Motor on Youtube!?

Hi Craigy

I like the idea of the single Disks stacked together as you can alter the offset and also the spacing to suit the Stator magnets.

Knocked up some CNC code below and tempted to mill out some wheels in the shape shown to make 4 disks or clear the center and make it into a cylinder using individual disks . Then maybe place a thin strip of metal over each angle as such.

The shape probably needs altering to fit the original, but gives an idea of what I mean.








Cheers

Sean.

You know, I really do hope its something real.
As far as cleverness goes, both designs are well, rather clever.
The hard drive platter is a interesting material as well.
Good luck builders, at least it looks like fun tinkering with..

Nice idea Sean, I was thinking along similar lines, the metal strips to me used could be cut into triangles as i mentioned a while back or as you have thought create a magnetic gradient ( tooth) instead of cutting the metal into a funny shapes which was putting me off as it would be rather teadious. Doing it your way would mean cutting and stickin a small rectangular section of steel on each tooth, a lot easier if you can cnc the wheel.

Have you thought about he metal used? i have contemplated everything from sections of hard disk drive shielding to baked bean cans

I found about 100 ferrite beads today,( tubular 4 by 4mm)  and may well hot glue them to my rotors for a laugh, ( easier than cutting metal) I wonder what would happen with a crossfield array..Might be  good to use some of he stuff we learned on the dark side

I reckon any bits of thin Iron would be okay, as long as it is bendy enough to follow the angles.
Even popping an Iron bar in your lathe and doing some nice fat curly cuts of about 1mm shavings would do mate
They would follow the contour and could be stuck on easy enough.

As usual let me know if you want any disks cut. Be good to get a pattern and angles, along with the theory from the Artist first !

Reckon we been away too long on the Darkside sometimes hehehe

Interesting video. I may attempt a replication of this over the weekend. It would be interesting to measure the effects of a magnet on a single flattened screw. I was wondering if the flux being drawn to a point like that may draw eddy currents along bunching up at the point. That could be dispersing the lines, helping it "slip" past.  "Helical Flux Slip Motor"  =)

btw this is my first post here after reading the forums for the past week....losing sleep I might add.
