METHOD OF MANUFACTURING PERMANENT MAGNET |
摘要 |
Crystal fractured surfaces of raw meal powder having more equal crystal orientation relationship in the magnetic field are arranged to be assembled together so that a method of manufacturing a permanent magnet which has an extremely high degree of orientation can be provided. In this invention, raw meal powder (P) is filled into a cavity, the raw meal powder (P) is oriented in the magnetic field while being pressed or urged by pressing means that has a smaller area than the cross-sectional area of the cavity. Semi-finished product thus oriented is compression-molded into a predetermined shape in the magnetic field.
