Description

반모터의 재기동 여부 판별방법How to determine if the half motor is restarted

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명의 적용되는 전자식 모터제어기의 회로도.1 is a circuit diagram of an electronic motor controller to which the present invention is applied.

제2도는 모터기동시의 전류-시간 특성곡선.2 is a current-time characteristic curve when starting a motor.

Claims (1)

전자식 모터 제어 센터에서 모터의 재기동 여부를 판별하는 방법에 있어서, 모터의 열한계치 G를 설정하는 단계와, 모터의 전력 공급선으로부터 전류를 검출하여 검출된 직류전류를 미리 설정된 모터의 정격 전류값에 따라 디지털값으로 변환하여 중앙처리장치로 공급하는 단계와, 모터 기동시기동중의 열적 상태를 추적하여 그 변화량을 메모리에 기억시키는 단계와, 상기 모터가 정지된 후 재기동시 상기 열추적에 의해 계산된 현재의 모터의 열적 상태와, 상기 모터의 열한계치를 바로 전 기동시의 열적 상태와 비교하는 단계를 포함하고, 상기 모터의 열한계치(G)에서 현재의 모터의 열적 상태값(F)을 빼고난 나머지가 모터의 기동중의 열적 상태값보다 큰 경우에 모터의 전원공급용 릴레이를 여자시키게 한 것을 특징으로 하는 모터의 재기동 여부 판별방법.A method for determining whether a motor is restarted in an electronic motor control center, the method comprising: setting a thermal limit value G of a motor, detecting a current from a power supply line of the motor, and detecting the detected DC current according to a preset current value of the motor. Converting the digital value to the central processing unit, tracking the thermal state during motor start-up and storing the change amount in a memory; and the current calculated by the heat tracking when the motor is stopped and restarted. Comparing the thermal state of the motor and the thermal limit of the motor with the thermal state at the last start of the motor, and subtracting the thermal state value (F) of the current motor from the thermal limit of the motor (G). When the remainder is larger than the thermal state value during starting of the motor, the motor restart relay plate is excited. Alternative method. ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: It is to be disclosed based on the initial application.
