Abstract

A fan motor set locating structure includes a base seat and a motor set. The base seat has a bearing cup. At least one locating notch is formed on a top section of the bearing cup. A bearing is disposed in the bearing cup. The motor set includes an insulation support. One side of the insulation support is formed with a sleeve. The sleeve is capped on the bearing cup. The sleeve has at least one protrusion section protruding from the sleeve to the bearing cup corresponding to the locating notch. The protrusion section is engaged in the locating notch in abutment with the bearing. Accordingly, the motor set can be quickly fixedly assembled with the bearing cup to fix the bearing. Therefore, the number of the components is decreased and the assembling process is speeded.
