| description | High-temperature superconducting (HTS) rotating machines generate higher torque density than the conventional ones, thanks to the intensified magnetic flux. The magnetic flux is coming from the large current through the HTS windings. However, the critical current density of HTS tape under the external magnetic field shows a strong anisotropy. When is perpendicular to the - plane of HTS tape, is decreased. This degradation causes heat generation from the winding under large applied current. To overcome this issue, perpendicular to the - plane is deflected by magnetic plates (magnetic flux deflector), which are superposed on the top and bottom of the field-pole winding of the stacked coils. Hereby, the critical current of the field pole is improved. This provides a benefit to suppress heat loss and improves the critical current of the coils and flux-induced torque of the machine. In this paper, we report on the effect of flux deflection by using a variety of magnetic materials and the geometry to go along with the prototype Bi2223 winding. Optimization of the configuration of the magnetic flux deflector is studied and discussed based on the results obtained by 3-D electromagnetic analysis. |
