同样，通过转子内部磁轭将两段转子铁心进行机械和磁路上的耦合起来。

Also, both rotor cores are coupled mechanically and magnetically through the internal back yoke.

应用表面阻抗与输入阻抗概念，分别计算实心的转子铁心与非磁性金属槽楔的一相阻抗。

Using the surface impedance and the input impedance respectively, the impedance per phase for the solid rotor steel and the non-ferrous metallic slot wedges is calculated.

考虑到电机转子的实际结构，电磁力除作用在转子绕组上之外，更主要的是作用在转子铁心的表面和内部。

Owing to the practical construction of rotors, the electromagnetic force ACTS not only on the rotor winding but also on the rotor ferrite core.
