A control device includes a motor driving unit that supplies electric power to a motor according to a magnetic-pole-phase signal output from the motor; and a rotational-position detecting unit that converts the magnetic-pole-phase signal into a rotational-position detection signal and outputs the rotational-position detection signal. The rotational-position detection signal indicates a rotation amount and a rotation direction of an output shaft of the motor and has a higher resolution than the magnetic-pole-phase signal. |
