A driving control device of a motor includes: a motor driving unit, which drives a motor in response to a driving control signal; and a control unit, which determines an energization pattern applied to an armature coil based on a detected rotational position of the rotor, wherein the control unit starts rotation control by a preset first energization pattern when activating of the motor, wherein when a predetermined time period has elapsed, the control unit adjusts energizing timing to be a timing, at which a short of each phase is not caused at switching of the energization pattern, and then outputs the driving control signal to the motor driving unit so that the rotation control is switched to rotation control of a second energization pattern, which has a predetermined advanced angle amount with respect to the first energization pattern. |
