PROBLEM TO BE SOLVED: To provide a DC motor including a polarizing device having a semi-spherical, semi-spherical shell-like or spherical permanent magnet for radically eliminating coil overhanging by forming the permanent magnet as essential component means for the polarizing device into semi-spherical, semi-spherical shell-like shapes. SOLUTION: This polarizing device for the DC motor comprises: a case; the semi-spherical permanent magnet mounted on the inside of the case; a non-magnetic member provided on one side of the lower section of the permanent magnet; and the coil provided on the nonmagnetic member.
