Abstract
A motor includes a stator core held on a core holder, the stator core includes a stacked magnetic body having a plurality of magnetic plates with the magnetic plates being piled up in an axial direction. The motor also includes a core support portion provided in the core holder with the core support portion including a core mounting face and a core locating face. The core locating face is formed near a magnetic center of the stator core with respect to the axial direction and formed flat in the core holder in a radial direction. The stacked magnetic body is divided into two stacked magnetic bodies with a boundary position of the two stacked magnetic bodies being set near the magnetic center of the stator core and the boundary surface of one of the two stacked bodies abuts against the core locating face of the core holder in the axial direction.
