Abstract
A motor drive controller includes: a rotation status detector that detects a rotation status of a rotor of a motor and generates rotation status detection information corresponding to the detected rotation status; a rotation unevenness information generator that measures a rotation unevenness indicating a flutter characteristic of the motor based on the rotation status detection information and generates rotation unevenness information according to a result of measurement of the rotation unevenness; a control circuit that generates a driving control signal based on the rotation unevenness information and the target speed signal for controlling the motor to rotate in target speed corresponding to the target speed signal; and a motor driver that outputs a driving signal to the motor based on the driving control signal.
