Abstract
A motor control device includes a current detector which, in generating a feedback current value on the basis of the detection result of a three-phase AC current supplied from an inverter to a motor, generates a first current detection value based on a first sample timing and a second current detection value based on a second sample timing that is shorter than the first sample timing; a coordinates converter which converts the coordinates of the first current detection value and the second current detection value to q and d axes; and a detection current processor which generates a feedback current value from the coordinate conversion results.
