Direct-current brushless motor cooling fan with high conical stator stability

The invention relates to the technical field of direct-current brushless motor cooling fans, in particular to a direct-current brushless motor cooling fan with a conical stator high in stability, which comprises a base frame, a shaft sleeve, a bearing and an axis are arranged at the center of the top of the base frame, the bearing is mounted on the inner wall of the shaft sleeve, the axis is fixed in the bearing, and the conical stator is fixed in the base frame. One end of the shaft sleeve is connected to the base frame in an inserted mode, the taper stator is fixed to the outer wall of the shaft sleeve, the motor shell is fixed to the top, the taper magnet is combined to the inner wall of the motor shell, and the PCBA board is arranged at the bottom of the taper stator. Through interaction of magnetic repulsive force between the conical magnet and the taper stator, the magnetic repulsive force of the conical magnet to the taper stator obliquely presses the taper stator downwards, the taper stator is forced
