摘　　要：电机故障特征相量的确立是进行故障诊断的前提。全文对永磁直流电动机生产线上常见故障的机理进行了分析,并在此基础上提出了基于电流分析的永磁直流电动机故障诊断的特征相量确立和提取方法,为进一步实现故障的决策与分离奠定了基础。实验研究表明理论分析与实验结果是一致的。The establishment of fault feature vector is a precondition to fault diagnosis.The mechanism of representative faults on product line for low power permanent magnetic DC motor was analyzed and the methods to establishment and extraction of fault feature vector were put forward in this paper.The foundation for realization of decision-making and separation of faults was settled.The study on experiment shows the consistency between theory analysis and experimentation results.
