摘　　要：为提高中型高压电机起动性能的计算精度,建立了考虑轭部饱和及磁性槽楔对起动漏抗影响的等效磁网络数学模型,给出了用磁化曲线计算电机饱和效应漏磁通的计算方法,并以实验样机计算了异步电机的起动性能。结果表明,计算数据与实测数据误差很小,有效提高了中型高压电机的起动性能计算精度。To improve the calculation accuracy of starting performance for medium-sized motors with high-voltage,in the condition of considering saturated yoke and magnetic wedge,the equivalent magnetic network model was set up.The paper proposed the method of calculating saturated leakage flux with the magnetization curve,and calculated the the starting performance by experimental prototype.The result indicates that the data obtained by the method the paper has less error than data actually tested.The calculation accuracy of the starting performance for medium-sized motors with high-voltage was effectively improved.
