A circumferential confronting type motor includes an armature core that has drive coils wound around its plurality of poles, and a drive magnet positioned opposite to the armature core in the radial direction. The drive magnet has a plurality of divided magnetized sections, each with a magnetic center, formed separated from each other in the axial direction by a non-magnetized section. The magnetic centers of the respective plurality of divided magnetized sections are provided in symmetrical positions with respect to a magnetic center in the axial direction of the armature core. Further, electromagnetic action between the drive magnet and the armature core causes the two to rotate relatively, while magnetic action between the plurality of divided magnetized sections and the armature core regulates their relative movements in the axial direction. |
