Abstract
A motor control device includes a velocity detection unit, a motor control unit, a phase difference detection unit, and a correction value calculation unit. The velocity detection unit detects each velocity of a plurality of driven bodies or of a plurality of motors which independently drives a corresponding one of the driven bodies. The motor control unit independently controls each of the motors based on the velocity and a predetermined velocity directive value. The phase difference detection unit detects a phase difference among each of the driven bodies. The correction value calculation unit calculates a correction value for the velocity or the velocity directive value based on the phase difference.
