Abstract

본 발명은 엘리베이터의 리니어 모터 냉각장치에 관한 것으로, 종래의 냉각방식은 2차측 고정자(2)의 전기저항에 의한 발열을 1차측 가동자(1)의 외측표면이나 주행풍에 의한 1,2차측의 접촉으로 간접적으로 방산하도록 하고 있기 때문에 계속적인 엘리베이터의 운행으로 인해 발생되는 2차측 고정자의 열에너지의 생성은 2차측 도체에 집적되고, 엘리베이터는 사용빈도에 따라 각기 다른 2차측의 전기저항으로 운행됨으로써 안정된 특성의 엘리베이터의 운행을 어려운 문제가 있는 바, 고정자(12)의 내부에 냉각수통로(12a)를 형성하고, 고정자(12)의 외측에 이 냉각수통로(12a)와 연결되는 외부냉각관(21)을 설치하며, 상기 외부냉각관(21)의 상부에 압축기(22)를 설치하고, 상기 냉각수통로(12a)의 유입구 부위에 냉각수통로를 흐르는 냉각수의 온도를 감지하는 온도감지센서(23)를 설치한 본 발명을 제공하여 고정자에서 발생되는 열을 직접적으로 방열시키도록 하여 냉각효과를 극대화시키도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a linear motor cooling apparatus of an elevator, and the conventional cooling method is to generate heat generated by the electrical resistance of the secondary stator (2) by the outer surface of the primary side mover (1) and the primary and secondary sides by running wind. Since heat is indirectly dissipated by the contact of, the heat energy of the secondary stator generated by continuous operation of the elevator is accumulated in the secondary conductor, and the elevator is operated by the electrical resistance of the secondary side which is different according to the frequency of use. Since there is a problem that it is difficult to operate an elevator having a stable characteristic, an external cooling pipe 21 is formed inside the stator 12 and connected to the cooling water passage 12a on the outside of the stator 12. The compressor 22 is installed on the upper portion of the external cooling pipe 21, and the temperature of the cooling water flowing in the cooling water passage at the inlet portion of the cooling water passage 12a is installed. Illustrated is one to provide the present invention is installed a paper sensor 23 and to direct the heat to the heat generated in the stator to maximize the cooling effect.
