| Popis: | High temperature superconducting (HTS)-coated conductors show various advantages in practical applications because of its zero resistance and large current capacity. Owing to the superior properties of HTS material in high magnetic fields, the HTS linear synchronous motor (LSM) is able to output high performance at relatively large air gap. Many experiments and prototypes have been implemented, which requires great consumption of HTS-coated conductors. In this paper, an analytical model of coreless HTS LSM was established and the magnetic flux density dependence of the critical current density of HTS-coated conductors was taken into account. An HTS-generalized racetrack coil was introduced to the analytical model for easy parameterization. A small scale prototype of the LSM which has a coreless stator and a HTS secondary was manufactured to validate the analytical model. It is indicated that the calculations have a good agreement with the experiments. As an application of the analytical model, an optimization task of the HTS LSM was carried out to improve its performances. |
