PURPOSE:To meet the demand of various magnetic pole intensities by forming a recessed groove or a hole for adjusting the magnetic pole intensity, between magnet poles of a resin magnet, or on the outside peripheral surface part corresponding to a magnetic pole position, the inside peripheral surface part, or the inside, etc. CONSTITUTION:The intensity of magnetic poles N2, S2 positioned at both sides of a magnetic pole intensity adjusting recessed hole 15 can be adjusted by placing the recessed groove 15 between specified magnetic poles of strong magnetic poles N1, N2, S1 and S2 magnetized by providing a multipolar anisotropy along the peripheral surface of a cylindrical or columnar resin magnet 10, and the magnetic pole intensity can be diversified. In this regard, an interval of the magnetic poles N1, N2, S1 and S2 can be set optionally by changing a position of an orienting yoke 11, and they can be arranged asymmetrically or symmetrically. Also, there is such an advantage as a surface working and a special groove working are not required after the molding. |
