We previously reported that an advanced preparation method was applied to the synthesis of a radially anisotropic composite bonded magnet with a continuously controlled direction of anisotropy for inner and outer rotor magnets. The preformed magnets were extruded and compressed into ring-shaped magnets by using self-recoverability based on the incomplete three-dimensional (3-D) network molecular structure at an elevated temperature. In this study, an investigation of the thermomechanical behavior of the self-recoverability of the magnets together with their magnetic properties was carried out in order to apply them to small motors as various specific shapes. As a result, the (BH) max of a magnet attained a typical value of 165 kJ/m3, and no deterioration of magnetic properties was detected throughout the preparation process even if the magnets were miniaturized at weights ranging from 38 to 400 mg. The reduction in size is attributed to the optimized incomplete 3-D network molecular structure.
