Abstract

본 발명은 리니어 모터의 단위 면적당 효율을 극대화시킴과 동시에 코일에서 발생되는 열을 효과적으로 방열시키기 위한 것이다.The present invention is to maximize the efficiency per unit area of the linear motor and at the same time to effectively dissipate heat generated from the coil.

이를 위해 본 발명은 상기 본체의 전면에 설치되며 함체를 이루는 본체(1)와, 전원인가시 자장이 발생되는 코일(4)이 권선된 복수개의 고정자 코어(3)를 가진 고정자(2)와, 상기 고정자 코어의 사이에 위치되게 본체의 상부에 설치되며 코일과 대응되게 영구자석(8)이 부착된 복수개의 가동자 코어(7)가 일체 형성됨과 동시에 본체의 상부로 노출되게 가동축(10)이 일체형성된 가동자(5)와, 상기 가동자가 승,하강시 가동자를 안내하는 안내 수단으로 구성하여서 된것이다.To this end, the present invention provides a stator (2) having a plurality of stator cores (3) wound around the main body (1) and the coil (4) generating a magnetic field when the power is applied to the front of the main body, The movable shaft 10 is installed on the upper part of the main body so as to be located between the stator cores, and the movable shaft 10 is exposed to the upper part of the main body while the plurality of movable cores 7 having permanent magnets 8 attached thereto correspond to the coils. The integrated mover 5 and guide means for guiding the mover when the mover moves up and down.
