Abstract

본 발명은 가동 철심형 리니어 모터에 관한 것으로, 종래 가동 철심형 리니어 모터는 고출력이 될수록 모터의 인덕턴스(INDUCTANCE)가 증가하여 비교적 스트로크(STROKE)가 작아지는 문제가 있고, 또한 모터에 상용전원을 가하면 모터의 동작 원리상 상용 주파수의 2배로 동작하게 되어 큰 스트로크를 내기가 어려운 문제가 있는바, 모터축을 중심으로 복수개 설치되는 원통형의 고정자와, 상기 고정자의 중심부에 권회된 권선과, 상기 고정자 내부에 강자성체로 형성된 가동자와, 상기가동자를 상기 고정자와 소정의 갭을 유지하도록 탄지하는 탄성부재로 구성되는 본 발명을 제공하여 가동자 철심이 양쪽으로 진동할 때, 양쪽 모두 각각 가동자의 위치에 따라 여자되기 때문에 종래의 모터보다 힘이 크고, 스트로크도 현저하게 증가하도록 한 것이다.The present invention relates to a movable iron core linear motor, and the conventional movable iron core linear motor has a problem that the inductance of the motor increases as the output becomes high, and the stroke becomes relatively small. Due to the principle of operation of the motor, operating at twice the commercial frequency makes it difficult to produce a large stroke. A plurality of cylindrical stators are installed around the motor shaft, a winding wound around the center of the stator, and inside the stator. According to the present invention, a movable member formed of a ferromagnetic material and an elastic member for holding the movable member and the stator to maintain a predetermined gap are provided. Because of the excitation, the force is larger than that of the conventional motor, and the stroke is also increased remarkably.
