The present invention relates to an electric motor for an explosion proof hoist of a new structure with improved explosion proof performance. According to the present invention, the electric motor for an explosion proof hoist can more effectively prevent an occurrence of a fire or an explosion due to a spark occurring when a motor main body (20) is operated or stopped by allowing an operator to couple and tighten a compression cap (A) to an extension pipe body (51) so as to compress a sealing member (52), thereby sealing a circumferential part of a power line (40).
본 발명은 방폭성능이 향상된 새로운 구조의 방폭 호이스트용 전기모터에 관한 것이다. 본 발명에 따른 방폭 호이스트용 전기모터는 작업자가 상기 연장관체(51)에 압축캡(A)을 결합하여 조이면, 밀폐부재(52)가 압축되면서, 상기 전원선(40)의 둘레부를 밀폐함으로, 모터본체(20)가 작동되거나 정지될 때 발생되는 스파크에 의해 화재나 폭발이 발생되는 것을 더욱 효과적으로 방지할 수 있는 장점이 있다.
