Abstract

이 발명은 브레쉬레스 직류모터에 관한 것으로서, 고정자에 의해 상대되는 회전운동을 하는 회전자의 위치를 회전자 위치 검출소자에 의해 회전자의 위치를 인식하여 전류를 적절히 절환/인가시킴에 따라 모터의 회전자가 한쪽방향으로만 회전 구동하도록 된 모터에 있어서, 영구자석과 대응되는 적층코어의 형상을 영구자석과 적층 코어에서 발생하는 코킹 토오그가 전기적으로 발생하는 토오크 리플이 감소되는 방향으로 위상 이동이 되도록 영구자석과 대응하는 면쪽의 코어에 끝단(30) 모서리가 일측으로 삭설되는 단자(32)를 형성하여 영구자석(1)과 코어(3) 사이에 불균일한 갭(Gap)이루도록 구성한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a breathless DC motor, in which a rotor position is detected by a rotor position detecting element and a current is appropriately switched / applied by a rotor position detecting element. In a motor in which the rotor is rotated in one direction only, the shape of the laminated core corresponding to the permanent magnet is shifted in the direction in which the torque ripple generated by the caulking torque generated by the permanent magnet and the laminated core is reduced. The terminal 32 is formed so that the edge of the end 30 is cut to one side in the core of the surface side corresponding to the permanent magnet so as to form a nonuniform gap between the permanent magnet 1 and the core 3.
