비데오 디스크 플레이어의 구동모우터 제어장치Drive motor controller of video disc player

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

제2도, 제3도, 제4도는 본 발명의 부분회로도.2, 3, and 4 are partial circuit diagrams of the present invention.

제5도는 본 발명에 적용되는 기계적 구동부의 개략도.5 is a schematic view of a mechanical drive unit applied to the present invention.

Claims (1)

구동모우터(1)의 회전력을 전달받아서 회전하는 플라이휠(FW)의 마그네틱벨트(2)와 비교신호 발생장치(3)에서 발생되는 정현파 비교신호를 입력신호 정현부(4)에 인가하여 펄스화한 후에 증폭시키고, 증폭된 펄스를 분주회로(5)에 가하여 주파수를 ½로 낮추도록 하며, 분주회로(5)에 미분증폭회로(6)와 파형 정형부(7)를 차례로 연결하여서 전술한 분주펄스로부터 톱니파가 발생되도록 하고; 플라이휠(FW)의 정상회전수에 해당되는 펄스를 발생시키는 기준펄스 발생회로(8)에 증폭회로(9)와 미분회로(10)를 차례로 연결하여서 기준신호를 만들어 낸후 이 기준신호를 하나의 입력신호로서 구동신호 취출부(11)에 인가하도록 하되, 전술한 파형정형부(7)의 출력신호를 구동신호취출부(11)의 다른 입력단자에 인가하도록 하고; 가변저항(VR1)으로 출력전류의 크기를 조절하는 구동신호 취출부(11)의 출력단을 위상제어용 가변저항(VR2)과 비교기(12) 및 일단의 전류증폭기가 구비되어 있는 위상제어 및 출력신호 안정화회로(13)에 연결하여서 플라이휠(FW)의 회전속도를 정속으로 제어하도록 되어 있는 비데오 디스크 플레이어의 구동모우터 제어장치.Pulsed by applying the sine wave comparison signal generated by the magnetic belt 2 and the comparison signal generator 3 of the flywheel FW rotated by the rotational force of the driving motor 1 to the input signal sine 4 After the amplification, the amplified pulse is applied to the frequency division circuit 5 to reduce the frequency to ½. The frequency division circuit 6 and the waveform shaping section 7 are connected to the frequency division circuit 5 in order to divide the aforementioned frequency division. A sawtooth wave is generated from the pulse; The reference signal is generated by connecting the amplification circuit 9 and the differential circuit 10 to the reference pulse generating circuit 8 that generates the pulse corresponding to the normal speed of the flywheel FW, and then generates the reference signal. Apply to the drive signal extraction section 11 as a signal, but apply the above-described output signal of the waveform shaping section 7 to the other input terminal of the drive signal extraction section 11; Phase control and output signal stabilization of the output stage of the drive signal extraction unit 11 for adjusting the magnitude of the output current with the variable resistor VR1 is provided with a phase resistance variable resistor VR2, a comparator 12 and a current amplifier. A drive motor control apparatus for a video disc player, which is connected to a circuit 13 so as to control the rotation speed of the flywheel FW at a constant speed. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
