레이저 디스크 플레이어의 모터 제어회로Motor control circuit of laser disc player

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제2도는 본 발명에 따른 레이저 디스크 플레이어의 모터 제어 회로도이다.2 is a motor control circuit diagram of the laser disk player according to the present invention.

Claims (1)

레이저 디스크의 초기구동시 주파수 센서의 펄스신호를 인식하여 스핀들 모터를 일정속도로 회전시키기 위한 레이저 디스크 플레이어의 모터 제어 회로에 있어서, 레이저 디스크의 초기구동시 레이저 디스크를 구동하는 스핀들 모터에 전원을 직접적으로 인가하여 스핀들 모터를 초기 구동시키기 위한 수단과, 상기의 스핀들 모터가 일정속도로 회전된후에는 이를 검출하여 상기의 스핀들모터를 펄스폭 변조방식으로 제어하기 위한 제어수단으로 구성시켜서 됨을 특징으로 하는 레이저 디스크 플레이어의 모터 제어회로.In the motor control circuit of the laser disk player for recognizing the pulse signal of the frequency sensor at the initial driving of the laser disk and rotating the spindle motor at a constant speed, the power is directly supplied to the spindle motor driving the laser disk at the initial driving of the laser disk. And a means for initially driving the spindle motor, and a control means for detecting the spindle motor and controlling the spindle motor by a pulse width modulation method after the spindle motor is rotated at a constant speed. Motor control circuit of the laser disc player.
