Abstract
A motor control device includes a current command value calculating device calculating a basic current command value, a first compensation device compensating for a delay in the rotor magnetic flux response of the motor by amplifying the basic current command value, a first current command value limiting device for restricting a post-compensation current command value by a first current limiting value, a second compensation device calculating a compensation value for the amplified current command value, an adding device calculating the post-compensation current command value by adding the amplified current command value and the compensation value, and motor control device controlling the motor, the second compensation device calculating, as the compensation value, a command value corresponding to a portion limited by the first current limiting value of the amplified current amplification command value.
