Abstract:
In a fan motor, a stator unit of a motor that rotates an impeller includes an annular stator, the center of which is positioned on a central axis, and a housing including an accommodating portion that accommodates a part of a resin portion covering at least a part of the stator. At least one of a bottom face of the accommodating portion oriented to the stator in the axial direction and an inner side face of the accommodating portion oriented to an inner side in the radial direction is provided with a plurality of stepped portions. The stepped portions are different from each other in length in the axial direction when provided in the bottom face, and/or in length in the radial direction when provided in the inner side face. The bottom face, the inner side face, and the stepped portion are covered with the resin portion.
