ABSTRACT:
A method of making a metal core for alternating current applications by powder metallurgy is disclosed. Ferro-magnetic powder is pressed into a cross section of the core, with the thickness of the cross section approaching that below which the green density is no longer uniform throughout the volume of the part. Additional cross sections are pressed to meet the overall core thickness requirement when the sections are subsequently stacked. The sections are stacked in non contacting relationship and sintered. The sections are separated by an air gap or magnetic insulating medium.
