| 摘 要： | 本文提出一种用边界元法与磁路计算相结合来求解饱和电机气隙磁场分布的数值方法。对一台异步电机气隙磁场的分布,分别用公认的非线性有限元法及本文的方法进行计算,两种方法的结果很好地吻合,从而证明了本文方法的实用性。算例表明,本文方法保持了边界元法输入数据少、占用内存少,运算速度快,计算精度高的优点,又克服了边界元法在非线性问题中应用受到限制的弱点。

| Abstract: | This paper presents a method for the calculation of the magneticfields in the air gaps of saturated electrical machines,which is ba-sed on the combination of the Boundary Element Method and Ma-gnetic circuit calculation.The magnetic field in the air gap of aninduction motor is calculated by the method presented in this paperand the Finite Element Method respectively.The results of the twomethods are in good agreement with each other,which prove thepresented method is practicable.The example in this paper showsthat the method has the advantages of the BEM such as having gr-eat numerical calculation accuracy,needing less inputdata,occupyingless storages and taking less computation time while it gets rid ofthe disadvantages of the BEM that its applications are mainly limi-ted to linear problems. |
