双层实心转子异步电动机电磁转矩的磁场计算方法

Electromagnetic Torque Calculation Method of the Induction Motor with Double-layer Solid Rotor

提出了双层实心转子异步电动机电磁转矩的磁场计算方法。其基本思想是以涡流场的数值计算为核心，跨越双层实心转子分布参数的求取环节，直接由涡流场计算所得场量进行电磁转矩数值计算。与从等效电路理论出发的方法相比，计算准确性明显提高。

This paper puts forward the electromegnetic torque calculation method of the induction motor withdouble-layer solid rotor based on magnetic field calculation. It can be illustrated as the following: with theeddy current field numerical calculation being as centre, not through the calculation of the rotor parameters,the electromegnetic torque is calculated directly by the field values. Compared the method based on equivelantcircuit theory, it has a higher accuracy.
