Electromagnetic Performance Analysis of Fully Stator-HTS Fault-Tolerant Motors

摘要

High temperature superconductor (HTS) motor can offer high torque density, high efficiency and small size. However, they suffer from high cost cooling system. In this paper, a new fully stator-HTS fault-tolerant motor is proposed. The novelty of the proposed motor is that both the HTS armature coils and HTS field coils are placed in the stator. Therefore, just one cooling system can meet the requirements. Another key of the proposed motor is the fault-tolerant teeth configuration which is able to improve the fault-tolerant capacity. Finite-element results are given for verification.
