Abstract

본 발명은 모터의 직류(DC)브레이크의 동작상태를 감시하는 장치에 관한 것으로, 특히 육안으로 직접 점검하기가 까다로운 여러장소에 분산 설치되어 있는 모터를 용이하게 감지할 수 있도록 하는 모터브레이크 감지장치에 관한 것이다.The present invention relates to a device for monitoring the operation state of the DC (DC) brake of the motor, and more particularly to a motor brake detection device that makes it easy to detect the motor is distributed in a number of places that are difficult to check directly with the naked eye It is about.

본 발명은 육안으로 직접 점검하기가 까다로운 여러장소에 분산 설치되어 있는 모터를 제동하는 브레이크코일에 흐르는 전류에 대해서 상한치와 하한치를 감지하여 상기 제동전류가 상한치이상 또는 하한치이하인 경우에 이를 관계자에게 알려줌으로써, 이에 신속한 대처를 가능하게 함과 동시에 모터의 구동을 정지시킴으로써, 모터의 오동작으로 인한 사고를 사전에 방지할 수 있는 것이다.The present invention detects an upper limit value and a lower limit value for a current flowing through a brake coil for braking a motor that is distributed in various places where it is difficult to check with the naked eye. In addition, by enabling a quick response and stopping the driving of the motor, it is possible to prevent the accident due to the malfunction of the motor in advance.
