アップ回路。A DC motor control circuit that controls the motor to the desired rotation speed by comparing the reference pulse and the speed pulse from the motor using a phase comparator, and applying the output that passes through a loop filter made up of an operational amplifier to the motor driver. In the above, the feedback circuit of the operational amplifier is constituted by a parallel circuit consisting of a short circuit, a resistor, and a series circuit of a capacitor, and a changeover switch is inserted into each of the short circuit and the series circuit, and these are switched in conjunction with each other. A feedback circuit is formed by the short circuit, and the operational amplifier is used as a voltage follower circuit to output zero volts, and a preset power source is connected to the capacitor, and when the motor is started, the feedback circuit is formed by the series circuit, and at the same time, the voltage is stored in the capacitor. 1. A DC motor startup circuit characterized in that the DC motor startup circuit is configured to apply a preset voltage to a motor driver.
