Abstract
Method of introducing the coils of a superconductive exciter winding into slots formed in a winding support member of a turbogenerator rotor with respectively two coil sides formed of a multiplicity of mutually superimposed conductors in each slot, the slots having a radially extending cross section with the base thereof disposed at the radially inward end thereof, which includes winding first an inner coil and then an outer coil of a pair of concentric coils forming respective parts of a double coil into two of the slots spaced from one another in accordance with the respective width of the coil, the inner and the outer coils into the respective slots being continuously wound beginning at the slot base and in respective opposite rotary sense so that a non-interrupted transition from the inner coil to the outer coil occurs at the slot base.
