AMORPHOUS MAGNETIC COMPONENT, ELECTRIC MOTOR USING SAME AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to an amorphous magnetic component for a high output high speed electric motor, an electric motor using the amorphous magnetic component and to a method for manufacturing the amorphous magnetic component, in which an amorphous metal material is made into powder and the powder is compressed and molded to enable a core component having a complicated shape to be easily formed, and in which crystalline metal powder having superior soft magnetic properties is added to amorphous alloy powder to achieve improved magnetic permeability and packing density in compression molding. The method of the present invention comprises the following steps: crushing a ribbon or a strip of an amorphous alloy to obtain platy amorphous alloy powder; classifying the amorphous alloy powder, and mixing the powder and spherical soft magnetic powder for improving permeability and packing density to obtain powder mixture; mixing the powder mixture and a binder and molding the mixture into the shape of a magnetic component; and sintering the molded magnetic component to achieve magnetic properties.
