Description
To investigate the electromagnetic characterization of HTS coil under a travelling magnetic field, a no-insolation racetrack coil was wound with YBCO tapes. For comparison, another HTS coil which has the same geometric and structural parameters was wound with insolated tape between the layers. The coils were injected with DC current and a flat stator which has traditional copper windings and a controllable three-phase inverter was introduced to provide travelling magnetic field. These HTS coils were respectively operated in the external magnetic field from the stator and the different voltage and current response of the coils was measured by experiments. In addition, finite element method was applied in this work to furtherly study the electromagnetic stability of the no-insolation coil which is potentially going to perform as the field magnet of a HTS linear synchronous motor.
Key words: HTS magnet, electromagnetic characterization, no-insolation magnet, travelling magnetic field
