A motor driving apparatus (100) for causing drive current to flow in first and second armature coils (2, 3) of two-phases to rotate a rotator, includes a drive unit (200) configured to give first and second PWM pulse signals to ends of the first and second armature coils.
The drive unit (200) includes a first shift unit (230) configured to, when a difference between pulse widths of the first PWM pulse signals given to the ends of the first armature coil (2) is less than or equal to a first predetermined value, shift forward any one of pulses of the first PWM pulse signals, and a second shift unit (240) configured to, when a difference between pulse widths of the second PWM pulse signals given to the ends of the second armature coil (3) is less than or equal to a second predetermined value, shift backward any one of pulses of the second PWM pulse signals. |
