| Outline of Final Research Achievements |
We have studied strong magnetic field trapping to HTS bulk in high temperature superconducting (HTS) synchronous motor with single pulse magnetization. When the GdBCO bulk is magnetized by waveform control pulse magnetization (WCPM) method using a spiral type divided copper coil without an iron core which resembles the internal structure of the HTS synchronous motor, in the vicinity of the maximum trapped magnetic flux density obtained by cooling in the magnetic field, the bulk accompanied the magnetic flux jump and greatly increased the trapped magnetic flux density. We attempted magnetic field feedback WCPM with the target near the maximum trapped magnetic flux density, HTS bulk accepted application of magnetization energy which can not be realized by conventional PFM. As a result, the HTS bulk succeeded in capturing a strong magnetic field comparable to the maximum trapped magnetic flux density, and made a prospect of practical application of the PFM method.
