Abstract

본 발명은 스핀들모터의 급제동방법에 있어, 상기 스핀들모터에 연결된 홀센서의 출력신호로부터 스핀들모터의 회전속도를 감지하여 제동하되 스핀들모터의 회전속도가 일정 속도이하로 감속되었을시 위치 제어루프를 가동시켜 상기 스핀들모터를 급제동하고 속도가 충분히 감속되었을시 제어루프를 개방시키고 디스크 이젝트를 행함을 특징으로 한다.The present invention relates to a rapid braking method for a spindle motor, which detects a rotational speed of a spindle motor from an output signal of a hall sensor connected to the spindle motor and brakes the braking motor. When the rotational speed of the spindle motor is decelerated below a predetermined speed, When the spindle motor is suddenly braked and the speed is sufficiently decelerated, the control loop is opened and the disc is ejected.
