ABSTRACT:
An electric drive control device is provided with an electric machine having an asymmetrical salient pole, a current detecting portion, a phase converting device that converts the detected current into an axis current, and a current controlling device which generates a voltage command value based on the axis current and a current command value of the axis current. The current controlling device generates the voltage command value in response to the detected current and an offset angle of the center of a magnetic flux density distribution occurring at the salient pole, with respect to the center of an opening angle of the salient pole. In this case, the current controlling device generates a voltage command value corresponding to the detected current and the offset angle so the electrical characteristics are the same as when an electric machine having a symmetrical salient pole is used.
