Hi Sykavy,
Yes, making the slots and fingers will be quite a bit harder to make than just a flat surface rotor. But I think it has some big advantages since now the two poles are 'virtually' interlocking. So one might think that the need for the super small air gap will be reduced.
Iron filings have a permeability of next to nothing unless (professionally) pressed. So that would not be a real helpful solution in my opinion.
The main problem here is (as always) money... Like I said a factory where they make motor laminations will have no problem stamping out the laminations needed for a No-Back emf motor. But although I have no idea what it will cost to make such a core for you, I doubt that it is in reach of the 'common man'. Maybe having them laser cut is more do able.
