@Clanzer,

Time to look and see what old DC motors I have lying around.

Seems to me you are a lot closer using DC motor magnets since that is what Mylow is using on his working motors and motor magnets are not horseshoe magnets.

You would then have only one pole facing your rotor magnets, not both poles like you would have using a horseshoe magnet.

Don't forget that when you take two ARC ferrites from the same electric motor they are polar opposites. So yes .. when you use both pieces together offset from each other facing the same way .. you do still have a north and south side in that stator array as each ARC is the others polar opposite.

In other words - in the ARC pair taken from one electric motor both pieces get polarized through their thickness and as polar opposites one ARC has the north pole on it's outside ARC and the other piece has south on the outside ARC. 

So a pair of ARC ferrites  facing down to the rotor placed in the same orientation
are actually the same pole arrangement as a horseshoe thats facing the rotor plate.

Just like a horseshoe stator when you turn it around the other way the rotor goes the other way same thing happens when you flip the ARC pair around the other way.

queue,  Yes you are correct, and I do understand that fully, and you do have the same poles facing the rotor magnets. The difference is that it ends up not being the same thing!

Motor magnets are as you state, one will have one polarity and the other will have the opposite polarity, but when looking at just one, it is a single polarity with two edges facing downward. This causes the single polarity to prefer one of the two edges and possibly switch between them,  you will not get this effect using horseshoe magnets because each pole is only a single point and cannot switch the pole position like a motor magnet having two edges.

Did I even say that in a way that makes sense?

i understand your explanation thanks ..

There's a whole lot we don't understand about magnets and their fields how they work and interact with the world.. perfect domain for new discovery !

Boil your motor in water to loosen the glue and prevent damage to magnets when removing, try to find a motor with the same dims as mylows ( diameter ) if your usung .5x.5 x 2 " mags just a tip. measurments in pic are for reference only and do not depict actaul size alltho its pretty damn acurate!
