A motor control device includes a third harmonic calculation unit (60) configured to calculate a first third harmonic on a basis of an average value between a voltage command value of a maximum phase with a maximum duty ratio and a voltage command value of a minimum phase with a minimum duty ratio among three-phase voltage command values; an amplitude calculation unit (61) configured to calculate an amplitude of the three-phase voltage command values; a third harmonic conversion unit (62, 62′, 63, 65-67) configured to convert the first third harmonic into a second third harmonic on a basis of the first third harmonic and the amplitude; a correction unit (64) configured to correct the three-phase voltage command values by subtracting the second third harmonic from the three-phase voltage command values.
