Abstract (en)

[origin: WO02063751A1] An armature winding (10) for an electrical machine is formed of superconductive cable (16). To shield the superconducting wire from large AC magnetic fields and to minimize the mechanical forces and torques on the conductor components, the superconducting armature winding is placed in a slotted stator core (22). The superconductive cable is formed of multi-filamentary superconducting wire tape with an aspect ratio close to unity or is alternatively formed of continuous cables of superconducting wire. Magnetic wedges (26) disposed in openings of the slots shield the slot-embedded SC sinding from AC field components.
