摘　　要：考虑到高温超导块材独特的电磁特性,确立高温超导磁阻电动机样机的基本结构,并基于第二类超导体临界态模型,利用有限元方法分析该电机内部磁场分布、电抗特性和工作曲线,获得结果与常规磁阻电动机进行了比较。The basic structure of the recently designed HTS reluctance motor is proposed in the paper. Taking account of the Kim model for critical state of the type II superconductors and finite element method (FEM), the magnetic flux distribution, the reactance parameters and the operating characteristics of the motor is analyzed on basis of the computation results. The HTS reluctance motor with YBCO in the rotor possesses higher xd/xq which leads to higher output torque, power factor, efficiency, better operation stability and synchronizing performance at the same size compared with the traditional ones.
