PROBLEM TO BE SOLVED: To improve the torque response of a motor to be controlled in a motor control device for driving a motor on the basis of a field current command value and a voltage phase command value.SOLUTION: A motor control device for controlling a motor on the basis of a field current command value and a voltage phase command value calculates the field current command value on the basis of a motor driving voltage and motor rotational frequency, and calculates a feedback torque command value such that the motor rotational frequency is made coincident with a rotational frequency command value, and calculates a torque reference value on the basis of the motor driving voltage and the motor rotational frequency and the field current command value, and calculates a voltage phase command value on the basis of the motor driving voltage and the motor rotational frequency and the feedback torque command value and the torque reference value. |
