I doubt, till we get proper sizes. Magnet motor first of all is precision and positioning (exp - H.Johnson).

That's how it might look with 20x5mm magnets and 2mm gap (1:1 scale).
Wondering what Jose (author?) would say about it.

Hi!

There is one detail that is overlooked. If you substract 40 degrees from 90 degrees the result is 50 degrees. So the rotor magnet goes at 45 degrees from the horizontal line and the ring magnet goes at 50 degrees from the horizontal line.
I hope that somebody can make a good replication.

Possibly someone can spot what I've done wrong in this template for a layout.

Using the dimensions given there seems to be a collision with the magnets.

Hi!

In my humble opinion. You should mount one magnet at 50 degres from the horizontal line, then move the magnet up and on the same line of reference get the other 50 degrees for the second magnet and so on tll you fill the entire ring. If you make a wood or plastic template with the separations and the degrees already carved on the material used, you only need then is to add the magnets to the perfectly measured template. All the effort should be to get all the inside diameter of the ring evenly spaced for the magnets. And the spacer between the magnets is the same protrusion or kind of steps needed to fill the inside diameter. something like this /\/\/\/\ but having into account the 50 degrees needed. The rotor could be shortened if the magnets are too wide. The thing is to let only a small gap for the magnet to circulate freely.

Another idea is to put the rotor only without magnet cut at 45 degrees at the ends, centered on its axis and while moving it inside the ring, put a magnet in front of it at 50 degrees, move it and do the same thing with each magnet with that rotor in front of it.  When you get all the magnets installed, just cut the rotor to size and add to it the magnets needed.
Good Luck!

Hi!

The secret seems to be to get the ring magnet always to have exactly just 5 degrees more than the magnet that is in front of it at any given moment around the ring.
