摘　　要：故障信号的分析和处理是完成故障诊断的前提和基础。当感应电机运行时,故障特征容易被谐波分量与噪声淹没,导致难以准确提取故障特征信息。为此,可以将瞬时功率作为对象加以研究。本文通过仿真模拟了轴承与定子综合故障在三相平均瞬时功率中的表现,对运用其进行综合故障诊断可行性进行了分析。Failure of the analysis and processing is the Precondition and basis for the Diagnose.As many motors running asynchronously.Failure features would be Flooded by the Harmonic weight and the noise.Lead to Accurate extraction the information of the characteristic.So we can use the Transient power as the research Object.This paper Through Simulation Bearing and Stator comprehensive failure in the With a three wire average power is the instantaneous.To use a comprehensive feasibility diagnose the analyst.
