Abstract
Description
Claims (1)
- 모터의 각상을 미리 설정된 순서에 따라 여자시켜 모터가 구동되게 하는 모터 구동부(10)와, 상기 각각의 상전류(iA), (iB), (iC)를 검출하여 미분하는 미분기(20)와, 상기 미분기(20)에서 출력되는 각상의 신호를 적정 수준으로 증폭하는 증폭부(30)와, 상기 증폭부(30)에서 출력되는 전압을 기 설정된 기준전압(Vref1), (Vref2), (Vref3)과 각기 비교하여 그 비교결과에 따른 모터 회전자의 위치검출신호(ga-gc)를 생성하는 비교부(40)로 구성한 것을 특징으로 하는 센서리스 에스알엠.
