一种基于谐波分量的双三相永磁同步电机快速高效缺相故障诊断方法

This letter proposes a fast and efficient open phase fault (OPF) diagnostic method using the harmonic components for dual three-phase permanent magnet synchronous machines (PMSMs). The diagnosis consists of fault detection and localization, in which the indicator based on fourth harmonic is derived to detect whether OPF happens, and the indicator based on second harmonic is derived to locate the O...
