中文摘要：无铁心超导直线同步电机(Superconducting Linear Synchronous Motor,SLSM)具有大气隙、大推力、高效率等优势,是高速磁浮列车的核心牵引动力装置。为提高无铁心SLSM的推力性能,本文研究了跑道形线圈结构参数对电机空载磁场和推力的影响规律。首先,研究了跑道形超导励磁线圈结构参数对空载磁场和推力的影响规律;其次,厘清了跑道形初级线圈结构参数和双层匝数组合对推力的影响规律,明确了跑道形超导线圈的长宽组合,以及跑道形初级线圈的宽度、直线段长度和内外层匝数组合的选取原则,实现了无铁心SLSM的电磁结构优化和性能提升。最后,借助三维有限元方法,对优化后的无铁心SLSM进行了电磁力特性分析,验证本文研究。

外文摘要：Owing to the large gap,the high thrust and high efficiency,the coreless superconducting linear synchronous motor(SLSM)is taken as the propulsion device of high-speed maglev train.The dependence of the no-load magnetic field and forces on parameters of racetrack coils were summarized to optimize the coreless SLSM.First,the length of linear part and the wide were taken as variables to analyze the effects of superconducting racetrack coils on no-load magnetic field and thrust.Then,the influences of geometric parameters of the primary racetrack coil were discussed to optimize the coil pitch,the wide and the turns of the double-layer racetrack coils.Finally,electromagnetic characteristics of the optimized SLSM were discussed based on the finite element method to make the work strong.This work is benefit to the optimal design and characteristic analysis of coreless SLSM.
