I have been using aluminum rotors on aluminum hubs on a phenolic 
shaft for quite some time now, with no problems.  The axial
voltage stress down the shaft is about 3kV/in.  The shaft surface
is ribbed like an insulator, in order to resist surface flashover.
The bearing supports are phenolic plate, as well.
