    • A control device for an alternating current motor includes: a target current generating unit which generates a current order value, based on a torque order, as a d-axis target current and a q-axis target current on dq coordinates; a current detection device which detects an alternating current supplied to each phase of a polyphase alternating current motor; a coordinate transforming unit which transforms the alternating current detected by the current detection device into a d-axis current and a q-axis current on the dq coordinates; and a vector control unit which carries out a current feedback control so that the d-axis current follows up the d-axis target current and the q-axis current follows up the q-axis target current. The vector control unit further includes: an operation switching unit which, depending on whether a back electromotive voltage of the alternating current motor is greater than or equal to a predetermined value, calculates one of a d-axis deviation and a q-axis deviation from the deviation between the d-axis target current and the d-axis current and the other one of the d-axis deviation and the q-axis deviation from the deviation between the q-axis target current and the q-axis current; and an integration controlling unit which outputs a d-axis integration voltage order value proportional to an integral value of the d-axis deviation and a q-axis integration voltage order value proportional to an integral value of the q-axis deviation. An alternating current supplied to each phase of the alternating current motor is controlled based on an output of the integration controlling unit.
