ABSTRACT:
An axial fan motor comprising a cylindrical bearing boss having therein a bearing mechanism for supporting a rotational shaft of the axial fan motor and a stator core coupled to the cylindrical bearing boss is disclosed. The bearing boss is, at its one end portion, coupled integrally to an insulator so that said stator core is sandwiched between the insulator and another insulator so as to insulating the stator core. A stator-holding section is defined in a housing of the axial fan motor and the stator-holding section has a cylindrical bearing boss receiving portion whose axis is substantially coincident with the axis of the rotational shaft of the axial fan motor. The bearing boss receiving portion includes upper and lower engaging portions which are engaged with the bearing boss when the bearing boss is inserted into the bearing boss receiving portion so that the upper engaging portion carries the stator core through the insulator and the lower engaging portion engages with the other end portion of the bearing boss.
