Abstract
A DC motor control device includes a communication circuit configured to receive a control command specifying a target rotation amount for a DC motor, a sensor interface configured to receive a detection signal from a rotational angle sensor that outputs the detection signal every time the DC motor rotates by a certain rotational angle, a step counter that outputs a count signal every time the detection signal has been received a certain number of times, a controller that, based on the number of times the count signal received, determines a step count representing the total amount of rotation, and generates a control signal that controls the DC motor in accordance with the step count and the target rotation amount, and a drive signal generation circuit that generates a drive signal that rotates the DC motor in accordance with the control signal.
