摘要： A controller for a permanent magnet synchronous motor which includes a D-axis current command section and a Q-axis current command section. The D-axis current command section increases the command value of the D-axis current so as to set a judged value to be zero by leading the current phase when the judged value is positive. In addition, the D-axis current command section decreases the command value of the D-axis current when the judged value is negative. Moreover, the D-axis current command section holds the command value of the D-axis current at a predetermined minimum value when the decreasing command value of the D-axis current becomes smaller than the predetermined minimum value. The Q-axis current command section is responsible for supplying a command value of the Q-axis current.
