According to the present invention, a dual fan motor comprises: a main body (10) having a stator installed therein; a shaft (13) coupled to a rotor disposed to face the stator to be rotated therewith, and extending to upper and lower portions of the main body (10); a first fan (21) coupled to an upper portion of the shaft (13); and a second fan (31) coupled to a lower portion of the shaft (13). A first unidirectional bearing (40) is coupled to the first fan (21), such that an inner wheel of the first unidirectional bearing (40) is rotatably coupled to the upper portion of the shaft (13). Also, a second unidirectional bearing (50) is coupled to the second fan (31), such that an inner wheel of the second unidirectional bearing (50) is rotatably coupled to the lower portion of the shaft (13).

    본 발명에 따른 듀얼 팬 모터는 스테이터가 설치된 본체(10); 상기 스테이터와 대향되도록 위치하여 회전하는 로터와 결합되어 함께 회전하고 상기 본체(10)의 상부 및 하부로 연장되는 샤프트(13); 상기 샤프트(13)의 상부에 결합되는 제1 팬(21); 및 상기 샤프트(13)의 하부에 결합되는 제2 팬(31); 을 포함하여 이루어지고, 상기 제1 팬(21)에는 제1 단방향 베어링(40)이 결합되어 상기 제1 단방향 베어링(40)의 내륜이 상기 샤프트(13)의 상부에 회전 가능하도록 결합되고, 상기 제2 팬(31)에는 제2 단방향 베어링(50)이 결합되어 상기 제2 단방향 베어링(50)의 내륜이 상기 샤프트(13)의 하부에 회전 가능하도록 결합되는 것을 특징으로 한다.
