Abstract

본 발명은 반전직류전동기에 관한 것으로, 종래에 서로 반대방향으로 회전하는 반전부하를 구동하기 위해서는 서로 다른 방향으로 회전되는 2개의 모터를 사용하거나 하나의 모터와 반전기어를 사용하여야 하므로 공간이나 중량에 제한을 받는 곳에서의 사용은 대단히 불리한 문제점이 있다. 상기와 같은 문제점을 해결하기 위한 본 발명은 전원측 프레임브래키트(2)와, 부하측 프레임브래키트(3)와, 상기 전원측 프레임브래키트(2)에 일단이 회전가능하게 지지된 회전축(5)에 압입설치되는 내부회전자(10)와, 상기 부하측 프레임브래키트(3)에 구비된 베어링(24)에 부하측이 지지되고 전원측이 상기 회전축(5)의 일단에 회전가능하게 지지되어 설치된 외부회전자(20)로 구성되어 상기 내부회전자(10)와 외부회전자(20)가 서로 반대방향으로 회전되도록 된다. 상기한 바와 같은 본 발명에 의하면 하나의 전동기로 서로 반전되는 반전부하를 동시에 구동시킬 수 있는 이점이 있다.The present invention relates to an inverted DC motor, and in order to drive inverted loads rotating in opposite directions in the related art, two motors rotated in different directions or one motor and a reverse gear must be used. Use in restricted areas is very disadvantageous. The present invention for solving the above problems is the power frame frame bracket (2), the load frame frame bracket (3), and the rotary shaft (5), one end of which is rotatably supported by the power frame frame bracket (2) An external rotor installed by press-installing the internal rotor 10 and a bearing 24 provided in the load side frame bracket 3 and a power supply side rotatably supported at one end of the rotary shaft 5. The inner rotor 10 and the outer rotor 20 are rotated in opposite directions to each other. According to the present invention as described above there is an advantage that can be driven at the same time inverted load inverted with each other by one electric motor.
