Abstract
The invention discloses a cooling fan of a motor. The cooling fan comprises a cylindrical fan shell. Fan blades are arranged in the fan shell, and a driving shaft is arranged in the middle of the fan blades. A dustproof cover is arranged on the upper portion of the fan shell, and vent holes are distributed in the dustproof cover at equal intervals. The bottom of the fan shell extends towards the outer edge to form a fixed ring, and four arc-shaped convex blocks distributed at equal intervals are arranged on the edge of the fixed ring. Fixed mounting holes are formed in the arc-shaped convex blocks, and a plurality of locating columns are further arranged at the bottom of the fixed ring. The cooling fan of the motor is provided with the dustproof cover, and the situation that dust enters the cooling fan to influence rotation of the cooling fan is avoided. The locating columns are arranged at the bottom of the fixed ring, so that mounting and locating are facilitated, time and labor are saved, the structure is simple, and the good application prospect is achieved.
