ABSTRACT:
For fixing the winding ends (1, 2, 3, 4) of a stator winding in a dynamoelectrical machine, in which the winding ends have inner (2, 3) and outer layers (1, 4), which are mechanically and electrically connected to each other at the axially outer end, the winding ends are clamped between an outer ring (14) and an inner ring (15). The bracing of the two rings (14, 15) and of said winding ends is performed by filling pieces (16) being inserted between two neighboring winding ends (1, 2) in the circumferential direction of the winding overhang, of which filling pieces at least some are wedged in the radial direction with the two rings (14, 15) by means of retightenable wedges (17, 18).
This clamping produces a rigid winding overhang, the wedging can be retightened if required and also disassembled without any great effort.
