PROCESS OF MANUFACTURE OF SECTOR PERMANENT MAGNET WITH TEXTURE PARALLEL TO SYMMETRY AXIS OF SECTOR Russian patent published in 1995 - IPC

FIELD: manufacture of permanent magnets. SUBSTANCE: in process of manufacture of large-sized sector permanent magnet with texture parallel to symmetry axis first texture blank having shape in section formed by rectangle and segment adjoining it is created. This texture is parallel to symmetry axis of segment. Then blank is cut along lines drawn from ends of arc of section up to points of base distant from sides of rectangle by one quarter of width of its base. Parts of blank triangle in section are turned through 180 deg about points of base towards symmetry axis of blank till sector section is manufactured and are fastened together.
