| 摘 要： | 对电动机常见的断条故障、气隙偏心故障、轴承故障和转子不平衡故障,从机械和电气两方面进行诊断,介绍了它们的振动频谱特征和定子电流频谱特征。主要针对机械不平衡故障,对机械振动信号和定子电流信号进行了分析,探讨了电动机存在机械不平衡故障时,电流信号的频谱特征。 |
| 关 键 词： | 电动机 故障 综合诊断 机械不平衡 |

| Abstract: | Typical faults of broken rotor bars,air gap eccentricity,bearings and rotor unbalance are diagnosed from machine and electrical.The frequence feature of vibration signal and stator current signal is introduced.Machine unbalance fault is mainly analyzed in virtue of vibration signal and stator current signal.Feature frequence structure of current signal is discussed when machine unbalance fault is existed in the motors. |
| Keywords: | motor fault synthesis diagnosis machine unbalance |
