Abstract:
1. A radial anisotropic magnet manufacturing method comprising: fixing magnet powder in a net shape so as to maintain a magnetic anisotropic angle of a magnet with respect to a tangential line that is tangent to an outside border of the magnet; and performing a deformation with a flow so as to have a predetermined circular arc shape or a predetermined annular shape; wherein the pre-deformation magnet is a resin composite of which a microstructure includes a magnet powder stationary phase A and a flow phase B; wherein a part of the phase B is chemically coupled to the phase A so as to fix the stationary phase A group in a net shape; and wherein the magnet is deformed by a shear flow action and an extension flow action of the phase B.
