Document Type and Number:
Japanese Patent JP2672894
Kind Code:
B2
Abstract:
PURPOSE:To improve the reliability of a superconductive electric rotary machine by suppressing the distortion of the welding zone between a coil mounting shaft and an end plate, and preventing the drop of cooling function by the cracking of the welding zone hereby. CONSTITUTION:At least either a coil mounting shaft 21 or an end plate 22 is provided with thin cylindrical parts 21a and 22a extending in the axial direction, and the coil mounting shaft 21 and the end plate 22 are welded at these thin cylindrical parts 21 a and 22a. Accordingly, the displacement difference between the coil mounting shaft 21 and the end plate 22 is absorbed by the deformation of the thin cylindrical parts 21 a and 22a.
