The proposed method deals with the emerging technique called as Motor Current Signature Analysis (MCSA) to diagnosis the stator faults of Induction Motors. The performance of the proposed method deals with the emerging technique called as Motor Current Signature Analysis (MCSA) and the Zero-Sequence Voltage Component (ZSVC) to diagnose the stator faults of Induction Motors. The unalleviated study of the robustness of the industrial appliances is obligatory to verdict the fault of the machines at precipitate stages and thwart the machine from brutal damage. For all kinds of industry, a machine failure escorts to a diminution in production and cost increases. The Motor Current Signature Analysis (MCSA) is referred as the most predominant way to diagnose the faults of electrical machines. Since the detailed analysis of the current spectrum, the method will portray the typical fault state. This paper aims to present dissimilar stator faults which are classified under electrical faults using MCSA and the comparison of simulation and hardware results. The magnitude of these fault harmonics analyzes in detail by means of Finite-Element Method (FEM). The anticipated method can effectively perceive the trivial changes too during the operation of the motor and it shows in the results. 展开更多

在初期匝间短路故障检测中,故障特征频率的幅值很小,且易受到噪声信号的干扰,导致无法检测出故障信号。针对以上问题,提出了一种基于变分模态分解(VMD)与双对数频谱分析的永磁同步电机(PMSM)初期匝间短路故障检测方法。该方法利用VMD去... 在初期匝间短路故障检测中,故障特征频率的幅值很小,且易受到噪声信号的干扰,导致无法检测出故障信号。针对以上问题,提出了一种基于变分模态分解(VMD)与双对数频谱分析的永磁同步电机(PMSM)初期匝间短路故障检测方法。该方法利用VMD去除零序电压分量(ZSVC)中的噪声和相关谐波分量以突出故障特征分量。然后利用双对数频谱分析法对得到的信号进行频谱分析,通过检测频谱图中是否含有故障特征频率来判断电机匝间短路故障。通过仿真和实物试验验证了该故障检测方法的有效性。 展开更多
