为了选择为串联线性正式就职的操作效率的改进的三阶段的弯屈的一个合理模式，交通， magnetomotive 力量的时空特征被调查。串联线性正式就职马达的理想的模型被造，在哪个 B 和 C 阶段线圈分别地与由 d 的距离弯屈的 A 阶段被分开， e 槽投球并且没重叠。由从 1 ～ 5 改变 d 和 e 的价值，我们能获得与 d 和 e 的不同联合的三阶段的弯屈的 20 个不同模式。然后，空气差距 magnetomotive A 强迫 -- ， B- ，和 C 阶段线圈被 magnetomotive 力量理论计算。根据 A 的 magnetomotive 力量的短暂重叠 -- ， B- ，和 C 阶段线圈，在 20 个不同安排模式下面的理论、模仿的合成基本 magnetomotive 力量被获得。结果证明合成 magnetomotive 与 d = 强迫 2 并且 4 向前接近正弦曲线旅行的 e = 有 d = 的波浪和合成 magnetomotive 力量 4 并且 2 向后接近正弦曲线旅行的 e = 波浪，和他们的振幅和波浪速度近似不变、相等。在两个盒子中，马达能与高效率通常工作，但是在另外的 18 个安排模式下面(d = 1， e = 2；d=1,e=3；d = 1， e = 4；) ，合成 magnetomotive 力量介绍明显的脉搏颤动并且与可变速度移动，它意味着马达没通常工作并且有高精力损失。

英文摘要：

To choose a reasonable mode of three-phase winding for the improvement of the operating efficiency of cascaded linear induction motor, the time and space characteristics of magnetomotive force were investigated. The ideal model of the cascaded linear induction motor was built, in which the B and C-phase windings are respectively separated from the A-phase winding by a distance of d and e slots pitch and not overlapped. By changing the values of d and e from 1 to 5, we can obtain 20 different modes of three-phase winding with the different combinations of d and e. Then, the air-gap magnetomotive forces of A-, B-, and C-phase windings were calculated by the magnetomotive force theory. According to the transient superposition of magnetomotive forces of A-, B-, and C-phase windings, the theoretical and simulated synthetic fundamental magnetomotive forces under 20 different arrangement modes were obtained. The results show that the synthetic magnetomotive force with d = 2 and e = 4 is close to forward sinusoidal traveling wave and the synthetic magnetomotive force with d = 4 and e = 2 is close to backward sinusoidal traveling wave, and their amplitudes and wave velocities are approximately constant and equal. In both cases, the motor could work normally with ahigh efficiency, but under other 18 arrangement modes （d= 1, e=2; d= 1, e=3; d= 1, e=4;...）, the synthetic magnetomotive force presents obvious pulse vibration and moves with variable velocity, which means that the motor did not work normally and had high energy loss.
