基于高频电压扰动的永磁同步电机驱动器短路故障与电流传感器增益误差诊断与分类

Fault diagnosis of permanent magnet synchronous motors is often challenged by high misdiagnosis rates when stator short-circuit faults (SSCFs) and current sensor gain errors (CSGE) present similar fault signatures. Aiming to deal with such a challenge in real time, this article proposes an integrated fault diagnosis, localization, and classification framework based on high-frequency (HF) voltage d...
