Study on Electromagnetic Torque Calculation Method of the Induction Motor With Double-layer Rotor

提出了基于磁场的双层转子感应电动机的电磁转矩数值方法．该方法的基本思想是以涡流场的数值计算为核心，跨越双层转子分布参数的求取环节，直接由涡流场计算所得场量作电磁转矩数值计算．与从等效电路理论出发的方法相比，计算准确性明显提高．

The paper puts forward the electromagnetic torque numerical calculation method of the induction motor with double-layer rotor based on magnetic field calculation. It can be illustrated as the following: with the eddy current field numerical calculation being as a centre,not througt the calculation of rotor parameters, use the field values to calculate electromagnetic torque straight-forward. Compared with the method based on the equavelent circuit theory, it has a higher accuracy.
