Abstract
Magnetic properties of mechanically compacted glassy metal powder cores are presented. The powder size ranges from about 2 μm to 2 mm. The compositions of the powder materials are Fe78B13Si9, Fe40Ni38Mo4B18 and Co72.2Fe5.8Mo2B15Si5; the magnetostriction values of these are 30, 9, and 0.5 ppm respectively. The cores compacted with and without oxide binders are in a toroidal form. The effects of powder size, binder, value of magnetostriction and consolidation conditions on the properties are discussed. It is shown that cores made from near‐zero magnetostrictive powders exhibit core loss of about 12 W/kg and permeability of about 1600 at f=5 kHz and Bm=0.2 T, which are comparable to those for Ni‐Zn ferrite cores.This publication has 0 references indexed in Scilit:
