【摘要】 结合笼型异步电机的轻载和起动特性,对笼型异步电动机转子断条故障特征进行了机理仿真与实验分析。在此基础上提出了基于短时傅里叶变换(STFT)的异步电动机转子断条故障检测方法。实例结果表明,该方法是行之有效的。更多还原

【Abstract】 With the analysis of characteristic of cage induction machines under light load and start-up,this paper analyzed the fault features of rotor bar breaking,and a series of novel detection schemes are presented.That focuses on the early detection of the winding faults in asynchronous motors,as would help avoid catastrophic failure,reduce repair cost and outage time to a great extent.更多还原
