Abstract

본발명은 AC모터의 회전속도를 제어함에 있어서, AC 모터에 인가되는 전압에 대하여 위상차를 갖고 흐르른 전류위상의 제로 시점을 검출하여 전류동기부를 부가시켜 상기 전류동기부에서 검출된 제로시점의 전류동기신호를 마이콤에 입력시켜줌으로써 마이콤에서는 상기 전류동기신호가 입력됨이 감지된 후에 트리거신호를 출력시켜 AC모터의 회전속도를 정확하게 제어할수 있도록 한것임.The present invention, in controlling the rotational speed of the AC motor, detects the zero point in the current phase flows with a phase difference with respect to the voltage applied to the AC motor to add a current synchronous unit to the current of the zero point detected by the current synchronous unit By inputting the synchronization signal to the microcomputer, the microcomputer outputs a trigger signal after detecting that the current synchronization signal is inputted so that the rotation speed of the AC motor can be accurately controlled.
