Description
Claims (2)
- 모터(M)의 3상중 선택된 2상의 출력을 인버팅시키는 제 1, 제 2 인버터(I1)(I2)로된 인버터부(10)와, 상기 인버터부(10)를 통하여 입력된 신호와 인버터부(10)을 통하지 않고 입력되는 모터의 U상가 V상의 신호를 비교하는 제 1, 제 2 비교기(CO1)(CO2)로 된 비교부(20)와, 상기 비교부의 일출력을 클락으로 하고 타출력을 입력신호로 하여 에지를 검출하는 디플립플롭(FF)과, 상기 디플립플롭(FF)의 출력레벨로부터 정/역 회전을 검출하는 정역회전 검출부(30)를 구비하여 구성된 것을 특징으로 하는 모터의 방향 판별 회로.
- 제 1 항에 있어서, 상기 비교부(20)의 제 1, 제 2 비교부(CO10)(CO2)의 일측입력단자로 모터(M)의 U상과 V상이 입력되고, 타측입력단으로는 상기 제 1, 제 2 인버터(I1)(I2)를 거친 출력이 입력되도록 구성된 것을 특징으로 하는 모터의 방향 판별회로.
