摘要:
为了研究笼型异步电动机断条和静态偏心复合故障特征,采用多回路数学模型和改进的绕组函数法对复合故障下的定子电流特征进行了机理分析和仿真研究。首先建立笼型异步电动机的多回路数学模型,通过改进的绕组函数法计算了笼型异步电动机复合故障下的电感参数,推导了复
合故障在定子电流中产生的特定谐波频率计算公式,然后建立了笼型异步电动机正常状态和复合故障时的有限元仿真模型,通过仿真对理论结果进行了验证。结果表明,复合故障发生时定子电流中除存在单一断条和静态偏心故障的特征频率外,还会产生一系列附加谐波分量,理论分析与仿真结果相符。
Abstract:
In order to study the characteristics of composite fault of broken bar and static eccentricity in squirrel cage induction motor,the multi-loop theory model and modified winding function method were used to analyze the characteristics of stator current under composite fault. The multi-loop theory model of induction motor was established,and the inductance parameter of induction motor was calculated by the modified winding function method. The finite element simulation model of induction motor under composite fault was built. The results show that there are not only the characteristic frequencies of single faults of broken bars and static eccentricity,but also a series of harmonic components of composite fault in stator current. The simulation results match the theoretical analysis.
