A motor control device including: a voltage command value calculation unit configured to calculate a voltage command value of voltage applied to a motor, based on a q-axis current command value and a d-axis current command value; a driving circuit configured to output driving power to the motor, based on the voltage command value; a d-axis current command value calculation unit configured to calculate the d-axis current command value limiting the voltage command value to a maximum voltage applicable to the driving circuit or less by field-weakening control; a d-axis current command value limitation unit configured to limit the d-axis current command value; and a q-axis current command value limitation unit configured to limit the q-axis current command value lest the voltage command value exceed the maximum voltage due to limitation of the d-axis current command value by the d-axis current command value limitation unit.
