Abstract
PURPOSE: To provide a speed control system in use of DC motor enabling to obtain the stable speed control even for low power frequency of the frequency generator for speed detection.
CONSTITUTION: The power of the frequency generator 2 provided in direct connection with DC motor 1 is shaped in wave form with the amplifier 3, the multi circuit 4 having a certain metastable period actuated by power signal thereof and the power signal of inversion amplifier 6 are fed to AND gate 5 to obtain speed error signal. Further, the power signal of singale multi circuit 4 is fed to No. 1 trigger pulse generating circuit 9 to generate the narrow width pulse for applying to the set terminal of FF circuit 10, the power signal of said inversion amplifier 6 being applied to the re-set terminal thereof. The power of FF circuit 10 thereof is fed into the time voltage conversion circuit 11 with the power of said AND gate 5, the power signal thereof is transmitted to the monitor driving circuit 8 through the sample hold circuits 13, LPF 7.
