摘要
随着高功率永磁同步电机(PMSM)在舰船上应用的日益广泛,对PMSM的故障诊断和处理也日渐重要。PMSM的可靠运行是整个舰船系统的首要关注之一,而对PMSM的故障诊断是提高系统可靠性的关键。针对PMSM的基本数学模型,提出一种PMSM故障诊断方法,并得出了相应结论。
As the ever-increasing and spreading usage of high power permanent magnet synchronous motor （ PMSM）, the reliability of PMSM is getting more and more important in a system, especially in some warship power system. The key factor to improve the reliability is to conduct fault diagnosis to PMSM. Tthe model of PMSM is set up and several fault diagnosis methods are discussed, that is, sensor model and mechanism model have been built up and correspondent conclusion has been given as well as future development.
