Abstract
본 발명은 홀센서의 출력전압에 무관하게 모터를 구동하기 위한 최대전류를 발생하는 모터 구동 회로에 관한 것이다.The present invention relates to a motor driving circuit for generating a maximum current for driving a motor regardless of the output voltage of the hall sensor.
모터가 회전할때 모터의 절대 위치를 감지하여 자기량을 전기량인 전압인 홀전압(Vh)으로 변환시키는 홀센서(11), 홀전압(Vh)을 수신하여 이를 증폭하는 증폭수단(12), 증폭수단(12)의 출력에 따라 구동능력을 향상시키기 위한 버퍼수단(13) 및 상기의 버퍼수단(13)의 출력을 수신하여 모터를 구동하기 위한 전류(I)로 변환하는 전압전류변환기(14)로 구성된다.Hall sensor 11 for detecting the absolute position of the motor when the motor rotates and converts the magnetic amount into a voltage of the Hall voltage (Vh), which is an electric quantity, amplifying means (12) for receiving and amplifying the Hall voltage (Vh), According to the output of the amplifying means 12, the buffer means 13 for improving the driving capability and the voltage current converter 14 which receives the output of the buffer means 13 and converts it into a current I for driving the motor. It is composed of
