提出了施加电磁激励进行转子不平衡在线识别的方法，不平衡量可以无需改变转速在工作状态下得到识别，从而可实现旋转机械的无试重动平衡，实验结果表明，该方法具有较好的识别精度和工程应用前景。
The method of applying electromagnetic excitation to identify rotor unbalance online is proposed. The unbalance can be identified without any change of rotating speed in the working state, so that the system can be retested with no trial and error. The experimental results show that this method has better recognition Accuracy and engineering application prospects.
