Abstract
A method for driving a motor including a stator wound with a coil and a rotor rotatably disposed and confronting the stator, whereby the coil is energized and driven at energizing timing of which phase is determined based on an advance angle amount to rotate the rotor. At this time, it is determined whether or not a power supply voltage supplied to the motor exceeds a predetermined voltage, and when it is determined that the power supply voltage exceeds the predetermined voltage, the advance angle amount is changed to increase a current amount flowing through the coil, for energizing and driving the coil.
