本文讨论了采用块状超导体的内置式永磁同步电动机的电磁设计。研究了三种不同块体超导体在转子中的排列方式的IPMSM。还设计了使用永磁体的IPMSM。的IPMSM特性的评价：磁转矩，磁阻转矩，磁通密度，在室温下的损失。此外，所有的概念设计的转矩磁块/PM体积比进行评估。结果表明，超导IPMSM可以获得490 kNm/m3以上的电流密度，而传统IPMSM的电流密度仅为300 kNm/m3。
This paper deals with electromagnetic design of interior permanent magnet-type synchronous motors (IPMSMs) using bulk superconductors. Three kinds of IPMSMs with different bulk superconductor arrangements in the rotor were considered. IPMSMs using permanent magnets were also designed. The evaluation of the IPMSM characteristics: magnet torque, reluctance torque, magnetic flux density, and losses at room temperature are presented. Also, the torque-to-magnetic bulk/PM-volume ratio for all conceptual designs is evaluated. The results show that the superconducting IPMSM can obtain over 490 kNm/m3 against 300 kNm/m3 of conventional IPMSMs.
