摘要
提出一种计算笼形异步电机稳态特性的有限元模型。模型通过在气隙中设立人工边界 ,把电机场域分为定子和转子两部分。在转子侧采用叠加原理考虑各次空间谐波磁场的作用 ,利用气隙边界把定子场模型和各次谐波转子场模型耦合在一起。文中对一台电机进行计算 ,计算结果与实测值比较吻合。
The paper presents a finite element model for steady stage characteristics calculation for cage asynchronous motor.The field region is separated into the stator part and the rotor part by an artificial boundary in air gap.In the rotor region,the effect of space harmonics is taken into consideration based on superposition principle.The stator finite element model is coupled with rotor harmonics model by using the gap boundary.The model is applied to an asynchronous motor,and the result of the computed and experimental one matches well.
