Abstract

본 발명 단극마그네트를 구비한 직류모터에 관한 것으로, 종래의 직류모터가 그 구성이 복잡하고 효율이 떨어지는 문제점이 있어 이를 해결하기 위한 것이다. 상기와 같은 본 발명은 스커느(10S, 10'S)가 형성된 백요크(10, 10')에 부착되는 제1단극마그네트(M1) 및 제2단극마그네트(M2)와, 상기 단극마그네트(M1)(M2)사이에 구비되며 내주면과 외주면에 다수개의 자속안내부(21,22)가 구비된 코어(20)와, 상기 코어(20)의 자속안내부(21,22)들 사이에 외주면측에서 내주면측으로 하방향으로 권선되는 코일(C)을 포함하여 구성되어 입력전류의 방향에 따라 정역회전되는 것이다. 이와 같은 본 발명에 의하면 직류모터의 구성이 간단해지며 효율이 향상되는 이점이 있다.The present invention relates to a DC motor having a single pole magnet, and has a problem in that a conventional DC motor has a complicated structure and a low efficiency. The present invention as described above, the first single-pole magnet (M1) and the second single-pole magnet (M2) attached to the back yoke (10, 10 ') formed with the skein (10S, 10'S), and the single-pole magnet (M1) ( M2) between the core 20 having a plurality of magnetic flux guide parts 21 and 22 on the inner circumferential surface and the outer circumferential surface, and an inner circumferential surface on the outer circumferential surface side between the magnetic flux guide parts 21 and 22 of the core 20. It is configured to include a coil (C) wound downward to the side is to be rotated forward and backward according to the direction of the input current. According to the present invention as described above there is an advantage that the configuration of the DC motor is simplified and the efficiency is improved.
