Google "cogging" to see what I mean (its when a magnet pole passes some metal - like the stator winding - its "bumps" as the magnet passes the stator - that "bump" transfers to the mouting pole; which is mounted to the house. Each stator has multiple arms - and these things can spin pretty quickly - that generates a LOT of noise in the house - no problems when the wind isn't blowing... unacceptable when you are in it in a gale! This would still create "some" cogging - but due to the speed the stator passes the magnets it might be easier to eliminate... I like it.. good idea.. nice a simple too!
