Abstract

본 발명은 리니어모터에 설치된 보빈의 본체 상부둘레면의 제1래칫의 산에 직경이 급속히 축소되어 코일에서 발생되는 열을 냉각시키기 위해 공기가 유입되는 복수개의 유입공이 형성되고, 상기 코일이 권회되는 본체의 하부둘레면에는 제1래칫과 상호 어긋나도록 제2래칫이 형성되어 상기 유입공의 끝단이 제2래칫의 골과 고사이에 위치하여 유입공을 통과한 공기가 코일을 별도의 장치등이 설치됨이 없이 보빈자체로서 대류를 이용하여 효율적으로 냉각시킬 수 있을 뿐만 아니라, 리니어모터의 크기를 콤팩트화하여 설치공간의 축소 및 제작비용을 대폭 경감시킬 수 있으므로 인해 모터의 사용수명, 효율성 및 신뢰성을 향상시킨 것이다.The present invention is a diameter of the first ratchet of the upper peripheral surface of the main body of the bobbin installed in the linear motor is rapidly reduced in diameter to form a plurality of inlet holes through which air is introduced to cool the heat generated in the coil, the coil is wound A second ratchet is formed on the lower circumferential surface of the main body so as to deviate from the first ratchet so that the end of the inflow hole is located between the valley of the second ratchet and the air passing through the inflow hole to install a separate device. Without condensation, the bobbin itself can be cooled efficiently using convection, and the size of the linear motor can be reduced to reduce the installation space and significantly reduce manufacturing costs, thereby improving the service life, efficiency and reliability of the motor. It is.

이를 위햐, 본 발명은 분체(1)에 형성되며 코일(2)에서 발생되는 열을 냉각시키기 위해 공기가 유입되는 유입공(4)이 형성되는 제1래칫(3)과, 상기 본체(1)에 형성되어 코일(2)이 권취되며 유입공(4)을 통과한 공기가 코일(2)을 냉각시키도록 안내하는 제2래칫(5)으로 구성된 리니어모터의 보빈구조이다.To this end, the present invention is formed in the powder (1) and the first ratchet (3) and the main body (1) is formed with an inlet hole (4) through which air is introduced to cool the heat generated in the coil (2) It is a bobbin structure of a linear motor formed in the second motor 5 formed in the coil 2 to wind the air passing through the inlet hole 4 to cool the coil 2.
