Plus I would design the motor so one coil is actually two coils,in a sense to utilize both ends of the magnetic field that it creates. Example: the south end of the coil would have a north pole of a magnet approaching and the other end that is now a north field would have a south pole of a magnet in the same position.(wich is exactly how the brushless outrunners are set up) Ofcourse the whole thing would have to be designed with all the possibilities in mind and that's quite the challange but for some (me included) that's the fun part.
My idea is to size the coil such that it draws a known amperage at a known voltage under full load. Self-current limiting, if you will.

Making it 2 mating coils instead of one is a good idea as well.
