Abstract: The generation mechanism of electromagnetic noise in permanent magnet synchronous motors was introduced briefly. The noise suppression optimization strategies were summarized from both domestic and international perspectives, focusing on avoiding resonance phenomena, reducing electromagnetic force amplitude, and minimizing noise transmission efficiency. The future trends in PMSM electromagnetic noise optimization was discussed, offering insights for subsequent research in noise suppression.
