摘要
分析了鼠笼异步电动机转子断条故障时的频率特点,阐述了小波包变换异步电动机转子断条故障的频带特征,通过实例验证,得到的结论是正确的,从而为小波包变换在电动机故障诊断系统的应用提供了理论基础。
This paper analyzes frequency character of rotor bar breaking fault for cage asynchronous motor , reviews frequency division character of rotor bar breaking for cage asynchronous motor based on wavelet packet transform. Experimental tests validate the results obtained in t-his paper. Therefore it presents good bases for the use of WPT in rotor bar breaking fault for cage asynchronous motor,
