为了实现轴向间隙式电动机的小型化和轻量化，我们采用了Gd体高温超导体作为旋转磁场磁极。将该块体插入分裂式电枢脉冲铜线圈中，并在零场下冷却至77 K。将块状磁铁应用于高温超导旋转机械时，应减少脉冲场磁化的次数，以利于实际应用。因此，将单个脉冲电流施加到脉冲铜线圈以磁化块体。涡流式电枢绕组的俘获磁场分布和瞬态磁通特性与电枢绕组的径向尺寸密切相关。减小脉冲铜电枢线圈的直径，在块体的表面上的陷获磁通密度的分布变得接近于圆锥形。与螺线管的使用相反，涡流型电枢线圈对Gd体高温超导体的磁化的应用显示了外部磁通量到体的中心的快速干预。对具有最佳半径的涡旋型铜线圈的块体HTS的磁化是有用的，并且可以是用于旋转机器（诸如电动机和/或发电机）的应用块体HTS的有效技术。
We employed a Gd-bulk HTS as rotating field magnet poles aiming for a smaller and lighter axial-gap-type motor. The bulk was inserted in the split-type armature pulsed copper coils and cooled down to 77 K under zero field. Employing the bulk magnet to HTS rotating machinery, the number of pulsed field magnetizations should be reduced for practical use. Thereby, a single pulsed current was applied to the pulsed copper coils to magnetize the bulk. The trapped field distribution and transient flux behaviour strongly depend on the radial dimension of the armature coil with a vortex-type winding. On decreasing the diameter of the pulsed copper armature coil, the distribution of the trapped flux density on the surface of the bulk becomes close to a conical shape. In contrast to the use of a solenoid, the application of vortex-type armature coils to magnetization of Gd-bulk HTS shows a quick intervention of the external magnetic flux into the centre of the bulk. The magnetization to the bulk HTS of the vortex-type copper coils with an optimum radius is useful and may be an effective technique for applied bulk HTS for rotating machines such as motors and/or generators.
