Abstract
A superconducting field winding for the rotor of an electric machine having several winding sections, the conductors of which each have a predetermined permissible bending radius which is larger than the bending radius provided at the coil heads of the winding section, wherein two associated conductor sections of a winding section are always electrically connected at at least one coil head by means of a prefabricated yoke-like conductor element whereby conductors with relatively large conductor cross section need not be subjected to excessive tensile stresses at the coil heads thereby avoiding damage to their superconducting material.
