ABSTRACT:
Method of making pole segment for a Lundell-type AC generator rotor from a mixture of ferromagnetic particles and a fugitive binder where the teeth of the rotor are molded concurrently with the base of the rotor but from a mixture of particles which is different from the mixture used to mold the base. Thereafter the segment is fired to remove the binder and sinter the metal particles together.
