Why not take a computer CPU-type cooling fan apart and use that.
select a brushless 12v type something like this maybe:

(look for part 381-1069-ND if the link above doesn't work... note the 
above was a 10second search, you'll probably need 2 in parallel for the 
wattage, but you get the picture).

The fan normally has a permanent magnet while the computer powers a 
3phase coil to make the fan rotate.
Only, in your case, you would be mounting the permanent magnets 
stationary while mounting the coils on your rotating application to 
power the application.
