Abstract
A method and device for producing a radially anisotropic multipolar solid magnet adapted to different waveform widths are provided. A mold core is removed from a mold for molding the magnet, and outer oriented poles, the number of which is the same as that of poles of the radially anisotropic multipolar solid cylindrical magnet, are arranged outside the mold. The width of a front end of a single outer oriented pole is determined according to the desired width of a single waveform of the radially anisotropic multipolar solid cylindrical magnet after being magnetized. The sum L of widths or arc lengths of front ends of all the outer oriented poles is less than 0.9πD, particularly less than 0.7πD, where D is the outer diameter of a mold sleeve. Magnetic particles in a mold cavity are rotated with the mold only during magnetization.
