1. motor drive controller comprises:

  • CD-ROM drive motor is connected with a moving body directly or indirectly, drive this moving body according to target translational speed move;

    Detector is connected with above-mentioned moving body directly or indirectly, detects the present translational speed of this moving body, and the output testing result is as detector pulse signal;

    Control part, be electrically connected with above-mentioned CD-ROM drive motor and above-mentioned detector, receive above-mentioned detector pulse signal, calculate the poor of above-mentioned present translational speed and target translational speed, according to above-mentioned poor calculation control value of trying to achieve, when controlling value is controlled at be in the preset value scope after, calculate the pulse repetition frequency of drive pulse signal according to this controlling value, according to this pulse repetition frequency, the FEEDBACK CONTROL CD-ROM drive motor.
