摘　　要：通过引入高温超导材料,提出一种新型的超导直线开关磁阻电机结构。建立超导直线开关磁阻电机有限元仿真模型,考虑超导材料的非线性特性,搭建电机控制电路,并详细阐述控制电路实施过程。然后对计算结果进行分析,研究了超导直线开关磁阻电机的励磁电流、推力及法向力变化以及磁场分布等问题,对比分析了传统直线开关磁阻电机与超导直线开关磁阻电机的电磁力特性,结果表明了所提直线电机结构的可行性和有效性。A novel linear switched reluctance motor(LSRM） was presented by means of the introduction of the high-temperature superconductor(HTS） in this paper. Firstly,the finite-element model of the superconducting LSRM was established,and the strong nonlinear characteristic of HTS was considered,the implementation process of control circuit was described in detail. Secondly,the simulation results were carried out and the problems,such as the variation of the exciting current and thrust with normal force as well as the distribution of magnetic field,were analyzed. Finally,the comparisons between traditional LSRM and superconducting LSRM were conducted,the results showed that the proposed superconducting LSRM was feasible and advanced.
