Abstract: A motor includes a motor body, a bracket installed in the motor body, a rotating shaft, a bearing accommodated inside the bracket and supporting the rotating shaft, and a bearing supporter defining a plurality of pores. The bracket and the bearing define a bearing heat dissipation flow path between an outer surface of the bearing and an inner surface of the bracket, and the bearing heat dissipation flow path is configured to pass air therethrough. The bearing supporter is disposed in the bearing heat dissipation flow path, and the bracket defines a bracket through-hole configured to discharge air that has passed through the plurality of pores of the bearing supporter.
