摘　　要：提出了一种基于向量拟合的电机设备电磁干扰建模方法。模型建立所采用的数据是通过对实际干扰设备的端口特性进行测量得到,测量过程简单方便。提出的两种通用电路拓扑单元,其电路参数可通过向量拟合进行求解。最后通过对一台三相电机进行建模,进行了数据误差分析,验证了模型具有准确性。本模型可以在10 kHz^70 MHz的频域内对电机设备的传导电磁干扰作出分析。This paper presents a electromagnetic interference equivalent circuit modeling method of equipment.Model data are obtained by measuring the port characteristics of the equipment.The measurement process is simple and convenient.This paper presents two different equivalent circuit topology unit,the structural unit parameters can be obtained by method of vector fitting method.Finally,the paper conducted a data error analysis to verify the accuracy of the model.This model can be used to analysis electromagnetic interference of motor in 10 kHz^70 MHz.
