This paper proposes a new simple unified analysis about high-frequency torque ripples of permanent-magnet synchronous motors, which are originally caused by a super-injected high-frequency signal. The analysis shows components of the high-frequency torque ripples, a sufficient and necessary condition for attaining zero ripples, and so on. The analytical result leads directly to several torque-minimizing techniques, and verifies the effectiveness of the conventional torque-minimizing techniques in a unified manner.
