In a motor control apparatus that calculates a command value of an AC voltage outputted from an inverter on the basis of a target motor torque of the AC induction motor and controls the inverter on the basis of the AC voltage, the target motor torque of the AC induction motor includes a first target motor torque and a second target motor torque, wherein a high speed response is required in the first target motor torque in order to at least suppress torsional vibration, the second target motor torque is a lower speed response than the first target motor torque, and delay processing is carried out for the second target motor torque. In the calculation of the AC voltage command value, a magnetic flux current command value in which current responsiveness is slow with respect to an input is calculated on the basis of the target motor torque, and a torque current command value in which current responsiveness is quicker than that of the magnetic flux current command value is calculated on the basis of the target motor torque and the magnetic flux current command value. |
