The present invention relates to an in-wheel motor which comprises: a circular rim; a cover coupled to the rim and sealing the inside of the rim; a shaft disposed axially; a stator that surrounds the shaft to be fixed; a motor assembly disposed to surround the stator and including a rotating rotor; a ring-shaped magnet that rotates with the cover; a magnetic encoder including an encoder sensor that detects changes in magnetic flux of the ring-shaped magnet; and a shielding unit detachably coupled to the cover. According to the present invention, when performance of a magnet deteriorates, it becomes easy to replace a magnet with a new one, and external magnetic field shielding performance in an axial direction as well as a radial direction of the magnet can be increased.

    본 발명은 인휠모터에 관한 것으로서, 원형의 림, 림에 결합되며 림의 내부를 밀폐시키는 커버, 축 방향으로 배치되는 샤프트, 샤프트를 감싸 고정되는 고정자와, 고정자를 둘러싸도록 배치되며 회전하는 회전자를 포함하는 모터 어셈블리, 커버와 함께 회전하는 링형 마그넷과, 링형 마그넷의 자속 변화를 감지하는 엔코더 센서를 포함하는 자기식 엔코더, 및 커버에 착탈 가능하게 결합되는 차폐부를 포함한다. 본 발명에 의하면 마그넷의 성능 저하 시 마그넷의 신품 교체 작업이 간단 용이해지며, 마그넷의 축 방향은 물론 반경방향 외부자계 차폐 성능까지 향상시킬 수 있다.
