A permanent‐magnet synchronous motor (PMSM) with a concentrated winding generates vibration and noise resulting from the 2nd radial electromagnetic force. In preceding research, it has been shown that the D‐ axis negative current reduces the 2nd radial electromagnetic force. In contrast, a relationship between this force and the current has not been clarified. In this paper, it is demonstrated that this force is separated into three forces caused by the D‐ axis current, the Q‐ axis current, and the flux of the magnet. An equation correlating this force and the current is developed by using a finite element analysis. On the basis of this equation, vibration control is proposed to reduce this force. In addition, this proposed method is verified by experiment.
