| 摘要: |
| 为满足中低速磁浮用单边直线感应电机(single-sided linear induction motor，SLIM)的牵引制动特性要求，给出了两种备选设计方案：一种是八极-80槽(长度1 927 mm)，一种是八极(虚拟9极)-89槽(长度2 047 mm). 在结构空间、材料成本酌优考量的基础上，对SLIM的绕组极数、节距、匝数、槽型、布线等的快速准确定型，对两种SLIM设计方案分别进行磁路、磁势、等值电路、起动特性等的计算，给出相应的理论计算及仿真测试结果. 实验结果表明：两种备选方案均能满足中低速磁浮牵引要求，其中八极-80槽已经量产化，八极-89槽可行性已被验证. 对结果分析可以得知SLIM设计流程和相关特性计算方法能为中低速磁悬浮列车驱动用SLIM的优化设计提供参考，依据结构设计过程，可准确地计算出与SLIM动态控制有关的参数的静态值.

| Abstract: |
| Two designs of single-sided linear induction motor (SLIM) were proposed to satisfy the required traction of medium-low speed maglev train. Between these two designs,one has a primary core with 8 poles and 80 slots and a length of 1 927 mm,while the other one is a 8-pole-89-slot design with a length of 2 047 mm. With limited installation space and cost as constraints,magnetic flow path,magnet-motive loop,equal circuit coefficients and initial characteristics were calculated so that fast and accurate determinations of the winding number of poles,pitch,the number of turn,groove and wiring become possible. Theoretical calculation and FEA simulations were performed and the results showed that both designs satisfy the traction requirements of medium-low speed maglev trains. The 8-pole-80-slot SLIM is already in quantity production stage,and the feasibility of the 8-pole-89-slot design has been proved. The proposed design procedure of SLIM and the methods to calculate relative characteristics can not only be applied to optimize SLIM designs for medium-low speed maglev trains,but also provide a method to precisely calculate the static values of those variables for dynamic control of a SLIM.
