<P>PROBLEM TO BE SOLVED: To prevent transient characteristics from being impaired by feedback control when an unsymmetrical salient pole motor is used as a drive motor. <P>SOLUTION: A motor driven controller includes an electric machine in which the shape of salient pole is unsymmetrical, a current detector, a phase conversion processing means for converting a detected current into an axial current, and a current control processing means for generating a voltage command value on the basis of the axial current and the current command value of the axial current. Further, the current control processing means generates the voltage command value corresponding to the deviated angle of the center of a magnetic flux density distribution generated at the salient pole to the center of the opening angle of the salient pole. In this case, the current control processing means generates the voltage command value corresponding to the detection current and the deviated angle. Accordingly, electrical characteristics are the same as those of the case that the electrical machine having shapes of the salient poles made symmetrical is used. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
