Abstract

PURPOSE:To control speed stably even when load suddenly changes by a method wherein a limiter circuit regulating the charge voltage of a capacitor at value slightly higher than speed setting voltage is mounted to the capacitor memorizing the inducing voltage of a DC motor. CONSTITUTION:A DC motor 13 is connected to a full-wave rectifying circuit A, and inducing voltage as the actual speed signals of the DC motor 13 is detected by means of a detecting circuit B and memorized to a capacitor 18. On the other hand, output from a saw-tooth wave generating circuit C which can be adjusted by means of a variable resistor 19 is generated at a terminal of a capacitor 25 and used as speed setting signals, but the charge voltage of the capacitor 18 is brought to value slightly higher than speed setting voltage by means of a limiter circuit F at that time. The charge voltage of the capacitor 18 and the speed setting voltage are compared by means of a comparison circuit E, a pulse generating circuit D is controlled by the output, and the gate trigger pulses of the full-wave rectifying circuit A are generated.
