PROBLEM TO BE SOLVED: To perform acceleration/deceleration of a motor speed at a high speed by vector control.SOLUTION: A motor control apparatus includes: a torque command restriction unit 115 that restricts the magnitude of a given torque command so as to be in a predetermined magnitude range; a q-axis current calculator 114 that outputs a q-current command IqC based on the torque command of which the magnitude is restricted by the torque command restriction part 115; a magnetic flux control unit 134 that outputs a magnetic flux command by using a magnetic flux generated from the current flowing in the motor 150 and a secondary magnetic flux command outputted in the magnitude depending on a rotation speed of the motor 150; and a motor driving unit 155 that drives the motor 150 by the q-current command IqC outputted by the q-axis current calculator 114 and a d-axis current command IdC obtained by the magnetic flux control unit 134. |
