i know very little about them but it is a fun thing to play with plus you get a few free neos , its very precise and low friction like you say. now i,ve experimented with it a bit it seems it doesent much care for having neos ( even a few ) mounted on the platters .... probably me ...thick fingers ...and a lack of patience .....that bit i know wont improve
the platters are strong (especially the older drives) but they will deform a bit and dont provide a flux linkage for the neos ( i had hoped they would )
plus the neos underneath tend to add eddy currents in the aluminium body , its a bit of a head scratcher ....everythings so small ...it would make a nice little project though ...i,ve pulled 6 of them apart so far
......free neos to clunk around
i was talking to a friend about options and he offered ( on loan ) Hugh Piggotts smallest axial design to play with , i havent seen this one but i "think" its got just four coils in the stator and his standard mags to suit , it is three phase and trailer hub mounted ....i should have it next week and i,ll post some pics
i see what you mean about the platter motor , its definately multi phase and will generate , the vawt rpm is the spanner in the works ....i never had a drag vawt as i wouldnt know how to get anything out of it
i do like the coffey can one though ....i made one out of a little plastic grease tub years ago , put it on a pole and watched it ...nada....it went a bit left ....then a bit right .....next time i looked up 2 days later it was purring happily away......
a spinning grease tub with no angle of attack .....impossible not to like
