description In accordance with the present invention, an in-wheel motor assembly including a rotor bracket provided with a cooling auxiliary protrusion, includes: a rotor comprising a rotor bracket connected to have an axis of rotation concentric with an axis of rotation of a vehicle wheel, and a magnet ring provided along the periphery of the rotor bracket with a plurality of permanent magnets disposed therein; a stator including a plurality of coils disposed along the periphery of the rotor, rotating the rotor with a magnetomotive force; and a motor housing provided to surround the rotor and the stator, and storing a cooling fluid for cooling and lubrication therein, wherein the rotor bracket includes a cooling auxiliary protrusion protruding laterally with respect to the direction of rotation of the rotor, increasing the fluidity of the cooling fluid housed inside the motor housing upon the rotation of the rotor. Therefore, the present invention is capable of considerably removing manufacturing costs due to a simple processing process. 본 발명에 따른 냉각보조돌기가 구비된 로터 브래킷을 포함하는 인휠 모터 어셈블리는, 차량용 휠의 회전축과 동심의 회전축을 가지도록 연결되는 로터 브래킷과, 상기 로터 브래킷의 둘레를 따라 구비되며, 복수 개의 영구자석이 배치되는 마그넷 링을 포함하는 로터, 상기 로터의 둘레를 따라 배치되어, 기자력에 의해 상기 로터를 회전시키는 복수 개의 코일을 포함하는 스테이터 및 상기 로터 및 상기 스테이터를 감싸도록 구비되며, 내부에 냉각 및 윤활을 위한 냉각유체가 수용되는 모터 하우징을 포함하며, 상기 로터 브래킷은, 상기 로터의 회전 방향에 대해 측 방향으로 돌출되어, 상기 로터의 회전 시 상기 모터 하우징의 내부에 수용된 냉각유체의 유동성을 증가시키는 냉각보조돌기를 포함한다.
