基于高频负序分量的永磁同步电机伺服系统匝间短路故障诊断方法

The working environment and operating states of the permanent magnet synchronous motor (PMSM) servo system make stator winding interturn short-circuits more likely, and the time-domain aperiodic fault characteristics also poses challenges for fault diagnosis. To address this, this article proposes a high-frequency negative sequence component-based fault diagnosis method. The rotating high-frequenc...
