Claim 9:
10. The motor control device according to claim 7, wherein the motor is a three-phase permanent magnet synchronous motor, and
wherein the motor control device includes:
an inverter circuit to drive the motor,
a phase voltage command calculation unit to convert a q-axis voltage command value Vq* after the q-axis voltage feed forward command value Vqff* is subtracted from the q-axis voltage command value Vqref, and a d-axis voltage command value Vd* after the d-axis voltage feed forward command value Vdff* is added to the d-axis voltage command value Vdref into a three-phase modulated voltage command value, and
a PWM signal generator to generate a PWM signal to PWM-control the inverter circuit on the basis of the three-phase modulated voltage command value.
