要約(英語): Permanent magnet synchronous motors (PMSMs) are widely used in various applications as high-power-density and highly efficient drive sources. However, a PMSM generates electromagnetic vibration because of the space and time harmonics. In this paper, we propose a synchronous PWM control method for shifting the carrier wave phase against the modulated wave. As the proposed control matches the ripple frequencies caused by the spatial and time harmonics, the ripple caused by the space harmonics is canceled by that caused by the time harmonics, with the phase shift of the carrier wave. The phase shift of the carrier wave is confirmed experimentally. In addition, it is experimentally verified that the vibration of the proposed method at a specific frequency is reduced by 46%@7,900r/min and 53%@19,500r/min.
