Abstract:
1. An iron core-equipped permanent magnet motor comprising an even number of radial anisotropic magnets: wherein the radial anisotropic magnets maintain a magnetic anisotropic angle of a magnet with respect to a tangential line by fixing magnet powder in a net shape, and have a predetermined circular arc shape or a predetermined annular shape by performing a deformation with a flow; 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; wherein the magnet is deformed by a shear flow action and an extension flow action of the phase B; wherein the radial anisotropic magnets are manufactured by (i) manufacturing a deformed magnet including a perpendicular anisotropic part α (ii) deforming the magnet into an annular shape or a circular arc shape so as to form a radial anisotropic part α wherein in the post-deformation radial anisotropic part α
