Abstract
An amorphous magnetic component for use in a high-power, high-speed electric motor, in which amorphous metal materials are powdered, compressed, and molded, to be easily molded into magnetic components of a complex shape, and crystalline metal powder of excellent soft magnetic properties is added to the amorphous alloy powder, to promote improvement of a magnetic permeability and improvement of a packing density at the time of compression molding. A method of manufacturing the amorphous magnetic component; includes the steps of: pulverizing ribbons or strips of amorphous alloys to obtain plate-shaped amorphous alloy powder; classifying the amorphous alloy powder, and mixing the amorphous alloy powder with spherical soft magnetic powder, in order to improve magnetic permeability and packing density, to obtain mixed powder; mixing the mixed powder with a binder, to be molded into a shape of the magnetic components; and sintering the molded magnetic components to implement magnetic properties.
