<P>PROBLEM TO BE SOLVED: To provide a control method that stably exchanges at high speed data between both inverters that control a double winding AC motor by transmission. <P>SOLUTION: The control method for the double winding AC motor drives the double winding AC motor 8 in which a first inverter power part 1 is connected to a first winding of the AC motor having double windings, and a second inverter power part 6 is connected to a second winding of the AC motor having the double windings. First and second transmission chips 4, 5 are mounted on first and second control boards 2, 3 that feed drive signals to the inverters, the transmission chips are connected with each other via a single transmission path 7, a variety of data such as a d-axis current command, a q-axis current command, a d-axis voltage command, a q-axis voltage command, a frequency command and a phase angle are set on the transmission chips at the first control board side, and transmitted to the second board side by transmission at high speed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
