FIELD: electrical engineering; manufacture of multipole rotors, motors, and generators. SUBSTANCE: multipole permanent magnet is produced by sintering cylindrical briquette of powdered retentive anisotropic material together with hollow cylinder 1. Hollow cylinder 1 is placed in mold provided with device for producing radial structure; cylinder may be made of steel or any other nonmagnetic material. External cylindrical surface of this material functions as one of surfaces of plane 2 for receiving powdered retentive anisotropic material. Second cylindrical surface of this plane is internal cylindrical surface of mold cylinders 3 and 4. Briquette is produced by molding in radially oriented magnetic field; briquette is ejected from mold together with cylinders 1 and 4, then cylinder 4 is removed. After that, briquette is sintered together with cylinder 1. EFFECT: simplified mechanical design, improved material utilization factor. 3 dwgn
