<P>PROBLEM TO BE SOLVED: To suppress an influence of an electromotive force generated in an AC motor. <P>SOLUTION: This drive unit of an AC motor is provided with: a feedback control part 13 which outputs a current command value corresponding to a difference between a current command value from a control device 20 and a current value detected by a current detector 17; parts 14, 15 each of which receives a current correction command indicating the current value corresponding to the electromotive force of the motor 30 from the control device 20, adds a current correction command value to the current command value outputted from the feedback control part 13, and outputs a current command value which is obtained by the addition; and a motor driver circuit 16 which feeds a drive current corresponding to the current command value outputted from each of the parts 14, 15 to the motor 30. <P>COPYRIGHT: (C)2010,JPO&INPIT |
