<p>An apparatus corrects a current value of a three-phase electricmotor including a current detector that detects current of each of three phases including a first phase, a second phase, and a third phase. The apparatus includes a current-value correcting unit (1). When current of one of the first to third phase is zero-crossing, the current-value correcting unit corrects a current value of at least one of the others of the first to third phases on a basis of a correlation between detection values of the current detectors provided for the others of the first to third phases during a period in which the three-phase electric motor is operating.</p> |
