Abstract
Description
Claims (1)
- 3상모터 회전방향 검출회로에 있어서, 상기 3상모터의 회전방향에 따라 120°의 위상차를 갖고 구동에 따른 전압을 발생하는 홀소자의 제1, 2감지부(10,20)와, 상기 제1감지부(10)의 양입력을 비교하여 모터회전 방향검출의 정보가 출력되는 제1비교기(30)와, 상기 제2감지부(20)의 양입력을 비교하여 소정주기의 방형파를 발생하는 제2비교기(40)와, 상기 제2비교기(40)의 출력을 충방전하는 충방전회로(10)와, 상기 제2비교기(40)의 출력과 충방전회로(50)의 신호를 논리화하여 래치클럭신호를 발생하는 논리회로(60)와, 상기 제1비교기(30)의 출력상태에 따라 논리회로(60)의 발생클럭에 의해 래치되어 3상모터의 회전방향을 검출하는 검출래치회로(70)로 구성함을 특징으로 하는 3상모터 회전방향검출회로.
