Abstract

PURPOSE: To enable control of speed without waiting time for counting an error pulse after unit time has passed by using a preset counter.
CONSTITUTION: The number of revolution of a motor DM is converted via a pulse oscillator 1 into pulses, which are applied through a waveform shaping circuit 2 and a coefficient circuit 4 to a preset counter 13. The number of revolutions per unit time is applied to the counter 13 by the input signal from an oscillator 12 for controlling the unit time. The preset counted value converted per unit time is substracted from the output signal from an input control circuit 4. Then, a speed deviation signal is applied to a memory 10 and a servo mechanism 11 to thereby adjust the field regulator Rh of the motor DM for a speed control.
