A driving control apparatus includes a controller that generates a first signal for controlling turn-on to a brushless motor, a PWM signal generator that generates a PWM signal for driving the brushless motor by continuous turn-on with a sine wave, and an inverter that supplies a driving voltage generated based on the first signal and the PWM signal for the brushless motor. The controller generates the first signal so that a turn-on section represented by the first signal continuously increases from a reference turn-on angle according to increase of a rotation speed, and the turn-on section having an angle corresponding to the continuous turn-on is kept when the rotation speed is equal to or greater than a predetermined speed. The PWM signal generator outputs the PWM signal in a range including a rotation speed at which the turn-on section begins to increase from the reference turn-on angle and more.
