Abstract
A motor control apparatus has an inverter that applies a voltage to an AC induction motor to be driven, a command value calculator that calculates a command value of an AC voltage outputted from the inverter based on a target motor torque of the AC induction motor, and an inverter controller that controls the inverter based on the command value 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. 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. Delay processing is carried out for the second target motor torque.
