Abstract

본 발명은 진동모터에 관한 것으로서, 본 발명의 목적은 모터의 내부구조를 단순히 변경하여 외부의 편심수단을 별도로 부가하지 않고도 진동을 유발할 수 있는 진동모터를 제공하는 데 있다. 이와같은 목적을 달성하기 위한 본 발명에 따른 진동모터는, 원통케이스 양측단의 부시 및 브러시홀더에 압입된 베어링으로 지지되며 삽입되는 회전자축과, 상기 회전자축의 외면에 무게편심이 생기도록 고정설치되는 코일홀더와, 상기 코일홀더외면에 부착되는 회전자코일과, 상기 회전자코일에 대향하여 원통케이스내면에 부착설치되는 영구자석과, 상기 회전자코일과 전기적 접속되도록 회전자축의 일측에 설치되는 정류자와, 상기 정류자와 외접하여 브러시홀더에 고정설치 된 브러시로 구성된 것을 특징으로 하여 모터의 전장을 줄여 소형화 시킬 수 있을 뿐만 아니라, 모터전체의 무게가 상대적으로 감소하여 소비전류를 감소시키는 효과가 있다.The present invention relates to a vibration motor, and an object of the present invention is to provide a vibration motor that can cause vibration without simply adding an external eccentric means by simply changing the internal structure of the motor. Vibration motor according to the present invention for achieving the above object, the rotor shaft is supported by the bearing pressed into the bush and brush holder at both ends of the cylindrical case and the fixed installation so that the weight eccentricity on the outer surface of the rotor shaft A coil holder, a rotor coil attached to an outer surface of the coil holder, a permanent magnet mounted on an inner surface of the cylindrical case opposite to the rotor coil, and installed on one side of the rotor shaft to be electrically connected to the rotor coil. It is characterized by consisting of a commutator and a brush fixed to the brush holder externally with the commutator, not only can reduce the overall length of the motor, but also reduce the current consumption by reducing the weight of the entire motor relatively. .
