PROBLEM TO BE SOLVED: To provide an apparatus and method for controlling a motor speed that stably changes a speed of a motor by adjusting duty update time intervals.SOLUTION: The apparatus for controlling a motor speed includes: a speed difference detecting unit 100 for calculating a difference between a motor control speed and a detected motor speed; a duty generating unit 300 for changing a duty on the basis of the speed difference detected by the speed difference detecting unit 100 and duty update time adjustment; and a time adjusting unit 500 for adjusting a duty update time on the basis of a duty variation in the duty generating unit 300. |
