トリガする手段とからなるモータ回転数制御回路。A circuit for controlling the rotational speed of the motor by controlling the phase angle of a three-terminal bidirectional thyristor inserted between the motor and the AC power source to control the current supplied to the motor, the circuit comprising: a one-shot multivibrator that receives a pulse input having a frequency proportional to the rotational speed of a motor and shapes it into a pulse signal having the same frequency as the input and a constant pulse width; and an output of the one-shot multivibrator is in a first state. a first filter circuit that outputs a voltage proportional to the frequency of the pulse input by being charged when it is in a second state and discharging when it is in a second state; and a sawtooth wave signal that is synchronized with the AC power supply voltage. a sawtooth wave generation circuit; a first comparator that receives the output of the first filter circuit and a setting signal and compares these signals; and a first comparator that is charged when the output of the comparator is in a first state. , a second filter circuit that discharges and outputs a smoothed voltage when in the second state; and a second filter circuit that receives the output voltage of the second filter circuit and the output of the sawtooth wave generation circuit as inputs. A motor rotation speed control circuit comprising: a second comparator for comparing the results of the comparison results; and means for triggering the gate number of the three-terminal bidirectional thyristor with a signal indicating the comparison result of the second comparator.
