本文给出了一种由高温超导旋转磁场绕组和电枢绕组组成的超导同步电动机的概念设计。考虑超导线圈的自场和电枢绕组上的旋转磁场，对电机电枢绕组的交流损耗进行了实验和数值研究。YBCO涂层导体的最新发展提出了实现比传统机器尺寸和重量小得多的全超导机器的可能性。旋转磁场绕组和电枢绕组均由YBCO高温超导（HTS）线圈组成。为该超导同步电动机研制了一种低交流损耗电枢绕组。通过有限元法建模研究了机器的性能。通过考虑磁场和电枢主磁通线之间的角度，从第一原理计算机器的转矩。
This paper gives a conceptual design of a superconducting synchronous motor consisting of both high-temperature superconducting rotating field winding and armature winding. The AC losses of the armature winding of the motor have been investigated experimentally and numerically, by considering the self-field of the superconducting coils and the rotating magnetic field exposed on the armature winding. The recent developments of YBCO-coated conductors present the possibility of achieving a wholly superconducting machine of significantly smaller size and weight than a conventional machine. Both the rotating field winding and the armature winding are composed of YBCO high-temperature superconducting (HTS) coils. A low AC loss armature winding design has been developed for this superconducting synchronous motor. The performance of the machine was investigated by modelling with the finite-element method. The machine’s torque is calculated from first principles by considering the angle between the field and the armature main flux lines.
