Document Type and Number:
Japanese Patent JP2645242
Kind Code:
B2
Abstract:
PURPOSE:To control the movement of a superconductive field coil caused by an electromagnetic force for preventing the superconductivity destruction to be caused by a temperature rise due to friction by a method wherein a dummy slot is so made at one side or at each side of a slot as to be adjacent to the slot and then a packing is inserted into the dummy slot with the superconductive field coil fixed inside the slot. CONSTITUTION:Taper-shaped dummy slots 21 are made radially on teeth 20 between a plurality of slots 8 which are made around a coil installation shaft 7. After all the components are assembled including a superconductive field coil 9 set in each slot 8, a packing 22 is driven into one dummy slot 21 after another with the quantities well controlled, to apply the specified compressed preload in the slot width direction of the superconductive field coil 9.
