Beschreibung
Zusammenfassung:	The present embodiment comprises: a motor body having a space formed therein; a rotary shaft assembly having a rotor and a bearing mounted on the rotary shaft assembly having a rotor and a bearing mounted on a rotary shaft; a stator installed in a motor housing so as to surround the rotor; an impeller connected to the rotary shaft; and a bracket installed on the motor body and having a bearing housing portion for receiving the bearing, wherein the bearing housing portion has a bearing heat dissipating flow path through which air flowing by means of the impeller is exhausted to the outside of the bearing housing portion after passing between the outer surface of the bearing and the bearing housing portion. Thus, the air blown from the impeller can absorb heat of the bearing by being in direct contact with the outer surface of the bearing while passing through the bearing heat dissipating flow path, and there is an advantage in that better heat dissipating performance is achieved by the air through a heat sink surrounding the bearing.
