Abstract
Description
Claims (2)
- 모터(10)의 전류를 검출하는 전류검출부와, 상기 전류검출부의 전류를 필요한 레벨로 증폭하는 증폭부(11)와, 상기 증폭부(11) 출력과 PWM신호와의 직접비교로서 PWM신호를 차단하는 전류제한부(12)와, 상기 증폭부(11)출력과 마이크로 프로세서 제어신호와의 직접 비교로서 마이크로 프로세서 제어신호를 차단하는 과전류 보호부(13)로 구성됨을 특징으로 하는 직류 모터 구동의 전류제한 및 과전류 보호장치.
- 제 1 항에 있어서, 상기 전류제한부(12) 및 과전류 보호부(13)의 상기 증폭부(11)의 일정 출력 레벨 이상에서 도통되도록 역방향 접속되는 제너다이오드(D1)(D2)와, 제너다이오드의 도통상태로 바이어스되는 트랜지스터(TR1)(TR2)와, 상기 트랜지스터(TR1)(TR2)의 출력으로 각각 PWM신호와 마이크로 프로세서 제어신호를 검출하여 모터의 전류제한 및 과전류 보호신호를 출력하게 되는 앤드게이트(A1)(A2)로 구성됨을 특징으로 하는 직류 모터 구동의 전류제한 및 과전류 보호장치.
