The present invention relates to a wheel motor structure, in which dustproof and waterproof effects can be further improved and heat dissipation efficiency can be further increased. Disclosed is a wheel motor structure comprising: a stator; a rotor; a cover coupled to one surface of the rotor to cover one surface of the stator; a coupling shaft penetrating each of the stator and the cover; and an oil seal disposed in a space between the cover and the coupling shaft to seal the space. Heat dissipation fins extending in a radial direction project from both surfaces of the cover. Therefore, the dustproof and waterproof effects of the wheel motor structure can be further improved, and at the same time, the heat dissipation efficiency can be further increased.

    본 발명은, 방진 및 방수 효과가 보다 향상되는 동시에 방열 효율이 보다 증가될 수 있는 휠 모터 구조체에 있어서, 고정자, 회전자, 상기 고정자의 일 면이 엄폐되도록 상기 회전자의 일 면과 결합되는 커버, 상기 고정자 및 상기 커버에 각각 관통되는 결합축 및 상기 커버와 상기 결합축 사이 공간에 배치되어 상기 공간을 밀폐하는 오일실(oil seal)을 포함하고, 상기 커버는 양면에 방사 방향으로 연장되는 방열핀이 돌출 형성되는, 휠 모터 구조체를 개시한다. 이에 따라, 휠 모터 구조체의 방진 및 방수 효과가 보다 향상되는 동시에 방열 효율이 보다 증가될 수 있다.
