Question on wind turbine design

Are the poles on the top face of your magnets or at the ends? The former arrangement exists in circular disc magnets and the small bar mags used in brushless motors. You may find that you can get more coils in your motor by winding multiple winds around a piece of stiff plastic. Similarly with disc magnets, alternating N/S with a smaller gap between them you may have more magnets and more coils. Also in many hobby brushless motors, the gap between mags and coils is small, 1-2mm. Do you have the mag coil arrangement on both the top and bottom? I am assuming that you have centering bearings top and bottom, but do you have thrust bearings? These are cheap and are simply balls in a nylon ring at the cheapest end of the market. You would have to sandwich these between big washers or metal plate. I think if all of this was done, the efficiency and output would increase. Dave
