ABSTRACT:
A multi-layer armature winding for large turbine generator is wound with individual diamond coils around to the point where the sides of initially wound diamond coils lying in upper armature slot positions interfer with the placement in lower slot positions of the coil side of additional diamond coils to complete the winding. To avoid having to "raise the jump" the winding is completed using bar coils, individual bars of which having been laid in those lower slot positions prior to the placement of any diamond coils. The remaining bars are laid in the vacant upper slot positions and then electrically joined with the initially laid bars to complete the individual bar coils.
