In this motor drive method, a motor includes a stator around which a coil is wound, and a rotor disposed facing the stator and capable of rotating, and the coil is energized and driven to rotate the rotor at an energization timing having a phase based on the amount of advance. At this time, a determination is made as to whether or not a power source voltage supplied to the motor exceeds a predetermined voltage, and when the predetermined voltage is determined to have been exceeded, the amount of advance is varied so that the amount of current energizing the coil increases, and the coil is energized and driven. |
