Motor having airflow converging device

The present disclosure relates to a motor which comprises housing, a stator installed in the housing, an armature rotatably set in the stator, and an air deflector sleeved onto the armature. Wherein, the air deflector includes a bottom wall and a side wall. The side wall extends from the periphery of the bottom wall and surrounds the vanes of the armature. Furthermore, there is a predetermined angle between the side wall and the bottom wall to guide and center the airflow created by the rotary vanes of the armature for increasing the airflow rates and therewith improve the heat-dissipation capability.
