Abstract

PURPOSE: To obtain this servo-circuit that power consumed is little and servo- characteristics are excellent, by controlling a switching regulator in response to comparison value between the output voltage of the switching regulator and the error voltage of speed signals.
CONSTITUTION: A comparator 4 applies error voltage between reference signals from a reference signal generator 3 and the revolution speed signals of a motor 1 from a revolution detector 2 to a base of a transistor 5. A comparator 11 applies comparison voltage between error voltage put out from the comparator 4 and the direct current output voltage E of a rectifying circuit 18 to a pulse width modulation circuit 6. The pulse width modulation circuit 6 controls a duty ratio of the driving pulses of a switching transistor 13 in response to said comparison voltage.
