Abstract
A stator end-winding system is proposed in which the bars of the winding are bent outwards and describe a hollow cone. The supporting proceeds by a wedge-like braced inside ring, a segmented outside ring and supports which also have a wedging effect. The bracing of the inside ring and outside ring is made by tie rods, the outside ring being azimuthally tensionable. Therefore, it can be placed over the above-mentioned cone described by the bars without the necessity of disassembling the stator end-winding system.
