摘　　要：针对目前电机故障诊断方法,设计了一种基于LPC2290的电机故障诊断系统,给出了系统的软、硬件具体结构。利用小波包算法对电流信号进行故障分析,通过频段位置来判定电机的故障,为加强和深入对电机故障诊断的研究提供了一种准确、可行的故障诊断方法。According to the current methods of electromotor fault diagnosis, a fault diagnosis system based on LPC2290 for the electromotor is designed .The structure of software and hardware system is given, the current signal fault is analysed by wavelet packet, it is to judge the fault of electromotor by frequency place. It is supplied that an exact and feasible fault diagnosis method for strengthening and deepening the research of electromotor fault diagnosis.
