PURPOSE:To enhance the reliability of a superconductive rotary electric machine by containing a superconductive field coil in the slot of a coil mounting shaft, and then securing the coil with a wedge made of titanium alloy, thereby obtaining surfficient bending resistant stress even at cryogenic temperature time. CONSTITUTION:After a superconductive field coil 3 is contained in the slot of a coil mounting shaft 2, a wedge 19 made of titanium alloy is inserted fixedly to the hole of the slot. The titanium alloy preferably uses Ti-5Al-2.5Sn alpha phase titanium alloy. |
