中文摘要
本文通过引入凸极效应建模,开发了内置式永磁同步电机(IPMSM)在串联和并联绕组连接下的匝间短路(ITF)故障模型。该模型基于变形磁链模型,能够准确分析不同绕组连接方式下的故障特征,为电机故障诊断提供了理论基础。
English Abstract
In this study, the interturn fault (ITF) models of interior permanent magnet synchronous motors (IPMSMs) employing series and parallel winding connections were developed through the addition of saliency modeling to the surface-mounted permanent magnet motor models presented in a previous work. The saliency model was obtained by using deformed flux models based on both the fault winding flux inform...
