So do I, Paul, but it's up to Juan now to make first step...

If he has the ONLY working motor it would sure be a shame if it got lost in the mail. 
That would be the end of THAT!
Can't Juan take some GOOD closeup pics of the WORKING motor with a ruler beside it so we can see scale. We also need another video.
He also mentioned earlier of another design he had that was better, could he share that too??

I tried my hand at replicating this, but could only find ceramic ring magnets. I sized the printout of the pattern to my magnets, printed out the design and hot glued the magnets right on top of the printout, so I could get the right angles in the shape of the ring. I then hot glued the 2 rotor magnets to a square piece of wood angled EXACTLY like the printout and balanced them on a needle.
All of my magnets (18mm X 3mm) were N facing out on the stator and N facing out on the rotor, used 30 magnets on stator.
The rotor kind of tried to turn and wobble but it just...locked up!! Played around for at least a couple of hours trying different angles and lengths of the rotor but....no go.
I then placed the ring of magnets over the rotor and tried to turn the rotor by hand, you can feel the rotor cogging!!  It's like the back of the rotor's S pole is locking onto the sators N pole. The ring magnets suck! Where did he get the chess set that he got the magnets from??
So now I'm thinking I need to overlap the stator magnets more than halfway so that I cover the center opening, maybe that's why it's cogging, then use an odd number of magnets to prevent lockup. I don't know but I'm not giving up yet!!

Hi Everyone,

Here's a suggestion from Juan. I was telling him about how everyone is still having trouble tuning the motor. So he suggested that you try flipping the ring and tuning it with the magnets facing each other the other way 'round. In case this doesn't make sense, here's a picture to illustrate the point:

You see this is where it gets really suspicious. Now he's completely changing the design  .

He told me that the track can work both ways but that one way is easier to tune than the other. (not sure which). Anyway, for those who are building, it's worth a try.
