Thanks Janne this really helped.
Ive tried to post a link again.

Does this mean:
920 rpm gives 6 poles, so I place 6 or 12 rows of magnets on my rotor.
12 rows of narrow magnets will give power at lower rpm.
or 6 rows of wide magnets will give more power but at higher rpm.

Still I dont get the idea of 18 coils in stator.

cheers, J
