Abstract

본 발명은 코깅 토오그가 감쇠된 모터에 관한 것으로 모터의 아마츄어 회전시 급속한 자속변화에 따른 코팅토오크를 저감시키기 위하여 N극과 S극을 띤 마그넷(2)사이의 중성대(4)에 연자성체의 보조극(5)을 끼움으로써 자속의 변화를 완만하게 한 것이다.The present invention relates to a motor in which a cogging torque is attenuated, and a soft magnetic material in a neutral zone (4) between a magnet (2) having an N pole and an S pole in order to reduce coating torque caused by rapid magnetic flux change when the motor rotates. By inserting the auxiliary poles (5) of the change in the magnetic flux is gentle.

따라서 급속한 자속변화에 의한 코팅 토오크를 감쇠시키는 동시에 마그넷(2)을 견고하게 지지할 수 있는 것이다.Therefore, the coating torque due to the rapid magnetic flux change can be attenuated and the magnet 2 can be firmly supported.
