Description
본 발명은 모터 과열방지장치에 관한 것으로, 특히 모터 외피의 온도를 감지함으로써 모터 내부의 코일의 절연열화 또는 점진적인 열화를 방지할 수 있는 모터 과열방지장치에 관한 것이다.The present invention relates to a motor overheat prevention device, and more particularly, to a motor overheat prevention device capable of preventing insulation deterioration or gradual deterioration of a coil inside a motor by sensing a temperature of a motor shell.
종래의 모터의 보호방식은 모터 내부에 열감지용 서모스탯을 설치하는 방식으로, 내부 온도가 모터의 한계온도에 도달하는 때에 서모스탯의 접점을 동작시켜 모터의 전원공급 부분을 차단한다. 이 방식은 순간적인 고온에 대응하여 모터를 보호할 수는 있으나, 모터 내부 코일의 절연 열화 또는 점진적인 열화는 감지하지 못하여 모터의 고장을 야기하는 문제점을 가진다.Conventional motor protection method is to install a thermostat thermostat inside the motor, when the internal temperature reaches the limit temperature of the motor to operate the contact of the thermostat to cut off the power supply of the motor. This method can protect the motor in response to instantaneous high temperature, but it does not detect insulation degradation or gradual degradation of the coil inside the motor, causing a problem in the motor.
따라서, 본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로, DC 모터 외피의 열발생을 감지하여 상기 모터내부의 이상 온도 도달시 알람을 발생시켜 사전에 모터를 정비하는 데에 그 목적이 있다.Accordingly, the present invention is to solve the conventional problems as described above, the purpose is to detect the heat generation of the DC motor shell to generate an alarm when the abnormal temperature reaches inside the motor to maintain the motor in advance have.

Therefore, since the sensor can indirectly monitor the internal temperature of the motor away from the inside of the motor, it is possible to appropriately prevent insulation deterioration or gradual deterioration of the motor internal coil.
본 발명의 모터 과열 방지장치는 DC 모터의 외피에 장착되어 상기 DC 모터의 내부 온도를 간접적으로 검출하는 온도센서와; 상기 DC 모터의 외피에 상기 온도센서를 부착시키기 위한 접착 테이프와; 상기 온도센서에 의해 검출된 온도를, 소정의 알람 온도와 비교하여 제어작동을 행하는 온도 콘트롤러와; 상기 검출된 측정온도가 상기 알람 온도보다 높은 때에는 상기 온도 콘트롤러의 제어에 의해 경보신호를 발생하는 경보등 및 부저로 이루어진다.The motor overheat prevention device of the present invention is mounted on the outer shell of the DC motor and a temperature sensor for indirectly detecting the internal temperature of the DC motor; Adhesive tape for attaching the temperature sensor to the outer shell of the DC motor; A temperature controller which performs a control operation by comparing the temperature detected by the temperature sensor with a predetermined alarm temperature; When the detected measured temperature is higher than the alarm temperature, an alarm lamp and a buzzer for generating an alarm signal by the control of the temperature controller are included.
