Abstract (en)
Method for manufacturing powder magnetic core comprises the die being filled with first with soft magnetic powder, and then with hard magnetic powder, wherein the filling sequence is repeated altematingly, at least once with soft magnetic powder and at least with hard magnetic powder, with the poured powder being bounded through compacting. <??>Powder composite magnetic core manufactured as spatial element characteristic in that it has at least two spaces (1, 2) existing, with at least one space filled with soft magnetic material (1) and least one space being filled with hard magnetic material (2). <IMAGE>
