Magnets prepared from Nd-Fe-B based melt-spun powder, using a powder compacting press, have not been applied to thin arc-shaped magnets for small magnet motors up to now. We developed new techniques to prepare a granular compound with epoxy resin binder and to press it into arc-shaped segments with Ti- and C-ion-implanted upper and lower punches. Using these techniques, we made thin arc-shaped rare-earth bonded magnets (maximum thickness of 0.9 mm) for small magnet motors whose output power was less than 1 W. Both high motor efficiency and high mechanical output power were obtained for magnet made by the powder compacting press, compared with magnet made by the extrusion molding.
