摘要
In this paper, a doubly fed doubly salient high temperature superconducting linear motor (DFDS-HTSLM) is proposed for vertical transportation. The proposed DFDS-HTSLM adopts a five-phase doubly salient configuration. The stator consists of iron lamination only with no windings or permanent magnets. The mover houses both the copper armature winding and the HTS field winding in its outer layer and inner layer, respectively. By using the HTS field winding, the air-gap flux can be flexibly adjusted by controlling the DC current flowing in it. In addition, by using five-phase configuration, the proposed motor can realize the fault-tolerance operation easily, hence improving the reliability.
