摘　　要：基于电机二维非线性正弦涡流场有限元计算及有效磁化曲线的等效 ,用场路结合的方法分析电机的特性 ,考虑了集肤效应和铁心饱和对电机参数的影响。文中的计算实例验证了这一方法的有效性。本文在电磁场软件包EMAS的基础上开发的软件实现了上述方法 。A field circuit approach for accurate prediction of the steady state performance of squirrel cage induction motor is presented. The method is based on two dimensional complex nonlinear eddy current solution with the use of effective reluctivity. Skin effect and core saturation are considered in the field calculation. An application example is provided to demonstrate the effectiveness of the proposed approach. A software package based on EMAS has been developed for motors CAD and off line optimization of motor control.
