description | A rotor of a motor according to the embodiment of the present invention comprises: a rotor core which is connected to the shaft and is arranged with the same center on the inside of the stator with a gap from the stator; and a permanent magnet which is connected to the outer circumferential surface of the rotor core and is arranged in a ring shape with a gap from the stator, wherein the permanent magnet includes a plurality of unit magnets having different poles, and the magnetization pattern of each of the plurality of unit magnets is a Halbach pattern. According to the embodiment of the present invention, the magnetization pattern of the rotor may be closer to a sine wave, thereby improving the counter-electromotive force.
본 발명의 실시예에 따르는 모터의 회전자는 샤프트를 감싸 결합되며, 고정자와 간격을 두고 고정자의 내측에 동일 중심을 이루어 배치되는 회전자 코어, 및 회전자 코어의 외주 면을 둘러 감싸 결합되고, 고정자와 공극을 두고 링 형상으로 배치되는 영구자석을 포함하고, 영구자석은 서로 다른 극을 갖는 복수의 단위자석을 포함하고 복수의 단위자석 각각의 자화 패턴은 할박 패턴(Halbach Pattern) 인 것을 특징으로 한다. 본 발명의 실시예에 따르면 회전자의 자화패턴이 정현파에 더욱 가까워질 수 있어 역기전력을 향상시킬 수 있다. |
