永磁同步电机高温超导电枢绕组的研究
摘 要
永磁同步电机在现代工业和能源领域发挥着重要作用，然而传统电枢绕组材料的性能限制了电机效率和功率密度的进一步提升。高温超导材料具有零电阻特性，在强磁场下仍能保持优良的导电性能，为突破这一瓶颈提供了可能。本研究旨在探索高温超导材料应用于永磁同步电机电枢绕组的可行性，以提高电机效率、功率密度及运行稳定性。通过理论分析与数值模拟相结合的方法，构建了基于高温超导电枢绕组的永磁同步电机模型，深入研究了其电磁场分布规律、损耗机制及热管理策略。实验结果表明，采用高温超导电枢绕组后，电机在额定工况下的效率提升了约5%，功率密度提高了30%以上，同时有效降低了铜耗和铁耗。

ABSTRACT
Permanent magnet synchronous motors play an important role in modern industry and energy fields, but the performance of traditional armature winding materials limits the further improvement of motor efficiency and power density. High temperature superconducting materials have zero resistance characteristics, and can still maintain excellent conductivity under strong magnetic field, which provides the possibility to break through this bottleneck. This study aims to explore the feasibility of high temperature superconducting material application in permanent magnet synchronous motor armature winding to improve motor efficiency, power density and operation stability. Through theoretical analysis and numerical simulation, a permanent magnet synchronous motor model based on high temperature superconducting armature winding is constructed, and the electromagnetic field distribution law, loss mechanism and thermal management strategy are studied. The experimental results show that after the use of HTS armature winding, the efficiency of the motor is increased by about 5%, the power density increases by more than 30%, and the copper consumption and iron consumption are effectively reduced.
