Claims (1)

  1. 전동기의 최소한 하나의 위상권선을 통하여 흐르는 교류전류의 시간을 나타내는 교류 출력신호를 공급하기 위하여 그 전동기 권선을 지나는 회로 내에 있는 전류 샘플링 장치와, 상기권선 양단의 교류 전압의 시간을 나타내는 출력신호를 공급하기 위하여 그 권선에 인가되는 전기입력의 전압을 감지하도록 되는 전압 샘플링 장치와, 상기 전류와 전압 사이의 위상편차에 따라 변하는 출력을 공급하기 위하여 상기 전류 및 전압 샘플링 장치의 출력에 응답하는 위상 검출장치를 포함하는 교류 유도 전동기의 역률제어장치에 있어서, 제어신호를 공급하는 신호장치는 고정레벨신호에 뒤따르는 증가신호를 포함하고, 고정 레벨 신호는 역률 명령신호로 이루어지며, 제어장치는 상기 전동기 권선에 직렬로 연결되고 그 권선에 입력되는 전력의 각 사이클의"온" 시간의 지속기간을 상기 위상검출장치의 출력의 역함수로서 그리고 상기 신호장치의 출력의 직접함수로서 변화시키기 위하여 상기 위상 검출장치와 신호장치의 결합된 출력에 응답하여서, 선정된 시동기간동안 점차적으로 증가하는 전력입력이 전동기로 인가된 다음에 전동기가 상기 고정 레벨역률 명령신호에 의하여 제어되는 것을 특징으로 하는 유도전동기 역률 제어장치.
