ABSTRACT:
In a connection arrangement (10) for the stator winding of a turbo machine with two or more parallel circuits of individual conductors (26, 29) per phase, the individual conductors belonging to one phase form a phase group (25, 28) and run directly adjacent to one another in the stator body, the individual conductors of the winding are each connected from a winding connection (21, . . . , 24) to an external connection (15, . . . , 20) via a phase ring (32), which runs concentrically with respect to the machine axis (33).A simplification of the manufacture and assembly as well as a reduction in space requirements and an improvement in the thermal properties are achieved by the phase rings (32) of a phase group each being led together as a phase ring group (11, . . . , 14) from the winding connections (21, . . . , 24) to the external connections (15, . . . , 20).
