Abstract

PURPOSE: To control speed smoothly and stably, by mounting an integration circuit, which has fixed threshould value voltage and integrates difference between the output of signals generated synchronizing with the revolution of a motor and the threshold value voltage, to this motor speed controller for analogically controlling the speed of the motor.
CONSTITUTION: Signals A showing the speed of a mptor 2 obtained from a tachometer generator 1 are wave-form shaped and changed into signals B, and a mono- multivibrator 11 functions by the rise or fall of the signals to generate pulses C. The pulses C are integrated by means of an integration circuit 15 consisting of a resistance 12, a condenser 13 and a CMOS inverter 14, and the speed of the motor is controlled so that the integral value of portions that exceed the threshold value voltage of the pulses C and the integral value of portions less than the threshold value voltage become equal. Since the speed of the motor is analogically controlled in this way, noises to a power source circuit, etc. are little, and speed can be controlled smoothly and stably.
