PROBLEM TO BE SOLVED: To provide a motor control device that can quickly reach a target rotation speed with saving power.SOLUTION: A motor control device has a controller 10 for setting a target rotation speed and a limit value, a servo equalizer 12 for generating a motor driving voltage signal according to the difference between the target rotation speed and the detected rotation speed, a limiter 14 for limiting the motor driving voltage signal by a limit value, and a driver 16 for driving a motor 18 by using the motor driving voltage signal limited by the limiter 14. The controller 10 sets as a limit value a driving voltage value which increases as the rotation speed increases and so that the increase at a relatively low rotation speed with respect to the driving voltage value of each rotation sped required to rotate the motor steadily is larger than the increase at a relatively high rotation speed. |
