【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]:In order to meet the requirements of single-sided linear induction motor SLIMs for medium and low speed maglev, two alternative design schemes are presented: one is 8-pole -80 slot (length 1 927 mm), the other is ocpole (virtual 9 pole -89 slot (length 2 047 mm). On the basis of considering the structure space and material cost, the SLIM winding pole number, pitch, turn number, groove shape, wiring, etc., and the magnetic circuit, magnetic potential and equivalent circuit of the two SLIM design schemes are respectively carried out. The corresponding theoretical calculation and simulation test results are given. The experimental results show that the two schemes can meet the requirements of medium and low speed maglev traction, in which the eight-pole -80 tank has been mass-produced, and the feasibility of the eight-pole -89 slot has been verified. The analysis of the results shows that the SLIM design flow and the calculation method of related characteristics can provide a reference for the optimization design of SLIM for the drive of medium-low speed maglev train, and according to the structural design process, The static values of parameters related to SLIM dynamic control can be calculated accurately.
