PROBLEM TO BE SOLVED: To obtain a motor in which the stator core 14 can be fixed dismountably with high accuracy through a simple arrangement. SOLUTION: A magnetic plate 14a2 disposed at the central position of magnetism in the laminating direction of a stator core 14 is abutted in the laminating direction, against the core positioning face 12a2 of a core supporting part 12a disposed at a position corresponding to the central position of magnetism in the axial direction of a drive magnet 23. Central position of magnetism on the stator core 14 side and the center of magnetism on the drive magnet 23 side can thereby be matched substantially. When a structure where the entirety of the stator core 14 is tightened to the core supporting part 12a by a screw member 13 inserted from the fixed motor board 11 side is employed, center of magnetism on the stator core 14 side can be set efficiently and highly accurately with respect to the center of magnetism of the drive magnet 23 by simply fixing the stator core 14 to the core supporting part 12a, the stator core 14 is secured rigidly with respect to the core supporting part 12a by means of the screw member 13, and dismantling of the stator core 14, repair by replacement of a component, and recycling are facilitated. |
