ABSTRACT:
A method for making an amorphous soft magnetic core using Fe-based amorphous metal powders is provided. The amorphous soft magnetic powders are obtained by crushing amorphous ribbons produced using a rapid solidification process (RSP). The magnetic core is obtained by performing a preliminary thermal treatment of amorphous metal ribbons made of Fe-based amorphous metal alloy using RSP, crushing the amorphous metal ribbons to thereby obtain amorphous metal powders, classifying the amorphous metal powders to then be mixed into a distribution of powder particles having an optimal uniform composition, mixing the mixed amorphous metal powders with a binder, forming a core, and annealing the formed core to then coat the core with an insulating resin.
