The most I could see needing in a stator/rotor group is 55. That would be a
5 ring setup and the diameter starts getting up there. 4 rings will likly be
a better upper limit keeping the diameter down while allowing more room for
bearing mounts. At 4 rings there would be 44 coil pairs. Any more and it
would be another group on the shaft slaved to the first.

Now I know why Digikey dosn't list the 24 :). 14vs20 pins is not much of a
factor at this point. Bigger problem is trying to build on a perfboard using
the newer surface mount styles. Once/if I get a working design for more
expermenting, I could go to surface mount parts and have the PC boards made
buy someone like pcb123.com.
