To provide a motor control device that prevents from becoming excessive correction, upon adding a backlash correction amount to a position command for a motor. Provided are: a positional error calculation part that calculates a positional error which is deviation between a converted first position detected value arrived at by converting a first position detected value which is the position of a movable part according to a rotation ratio between the movable part and the driven part, and a second position detected value which is the position of the driven part; and a position deviation calculation part that calculates a position deviation which is a difference between a position command and the second position detected value, in which the backlash correction part starts addition of the backlash correction amount when the variation of the positional error exceeds the first reference value, ends the addition of the backlash correction amount when the variation of the positional error exceeds the second reference value, and suspends the addition of the backlash correction amount when the position deviation becomes no more than the third reference value during correction.
