Smudges permanent magnet motor discovery PDF

Are all your magnets polarized the same way?  If the rotor magnets are polarized the same as the stator magnets you will need to stand the rotor magnets on edge for the polarity to be right.  In other words if the stator magnets all have the north pole facing out or the south pole facing out as per smudge's pdf then your rotor magnets have to be oriented so the pole faces are facing in the clockwise and counterclockwise directions.


Hope this helps.

the magnets are polarized as per smudge drawing, that is: all north facing out in stator (radial) and cw &ccw in the rotor (tangential). Exactly as your description.I`ll try to modify the rotor to enable an horizontal angular position to the magnets.

edited: the only ferromagnetic material present is in the bearings. The shaft is brass, the hub is aluminium.

Something else I want to try is making a stator with an odd number of magnets, or vice versa, 
an odd number in rotor (easier)

I see Smudge did add another PDF here
https://www.overunityresearch.com/index.php?topic=3984.msg86981;topicseen#msg86981


However I believe he must not have noticed my post pointing to this forum?


I will reach out to be certain he gets note!!


  This forum scrolls topics off the page very fast ...do to certain
"Multi thread Rapid fire posters " filling the forum with ??
And others seemingly unable to add to a still open ( not timed out as forum will do )
Thread ( seems a few "top of forum page phobias " ....


Such is life!!


Thanks for sharing your work!


I will try to add PDF above and also as mentioned reach out for Smudge


Thx

I have been keeping an eye on this thread.  The motor that Alvaro built with the rotor above the stator follows my suggestion for Jim Boot to try since he already had that set up.  However it is not the same as the motor in my papers where the rotor is within the ring of stator magnets.  So don't be disheartened that it didn't work.  There are examples of working motors using circular disc magnets, like the infamous Perendev/Brady one.  I think rectangular disc magnets would work better.  Not sure about cubic magnets though, my approach looks only at thin discs.

Edit.  My paper is purely theoretical and could be wrong!! I have no practical evidence to support it other than the motors you find on youtube using circular disc magnets.

Hello
Thank you for your interest Ramset. No need to unfold the PDF´s pages as there may be downloaded from the OUR page (which I did  ).
Dear Mr Smudge, inserting the rotor within the stator is my next idea to try (thought about it before reading your note above) but due to the small radius of my stator, 38 mm,I may use a different magnet for the rotor. I´ve got 10x10xmm at 1mm thick ones.
If those do not work, I´ll try another approach as you mentioned with circular diam. 20mm x3 mm thick.Another issue to consider is the distance between magnets in the stator, as it modifies-deforms the natural shape of the mag field.
