要約(英語): 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.
