    Abstract: There is provided a motor control device which enables torque ripple suppressing control high in followability by executing direct voltage control. A motor control device includes a voltage command calculation unit 15 which calculates a d-axis voltage command value Vdref and a q-axis voltage command value Vqref from a d-axis current command value id* and a q-axis current command value iq* of a motor 6, a feed forward command value calculation unit 23 which calculates a qi-axis voltage feed forward command value Vqff* for generating a q-axis current ripple on the basis of spatial harmonic parameters and the frequency characteristics of a motor winding, and a subtraction unit 10 which subtracts the q-axis voltage feed forward command value Vqff* calculated by the feed forward command value calculation unit 23 from the q-axis voltage command value Vqref calculated by the voltage command calculation unit 15.
