Abstract:
1. A connection arrangement for the stator winding of a turbo machine with two or more phases and phase windings with two or more parallel circuits of individual conductors per phase, and, for each phase, a first external connection configured and arranged to be connected to a winding start of said phase winding, and a second external connection configured and arranged to be connected to a winding end of said phase winding, the connection arrangement comprising: individual conductors belonging to each phase forming a first phase group configured and arranged to be connected to said first external connection, and a second phase group configured and arranged to be connected to said second external connection, said individual conductors of each phase group running directly adjacent and parallel to one another when in the stator body; phase rings running concentrically with respect to the machine axis and connecting each of said individual conductors of one of said phase groups to the respective external connections of said phase; and wherein the phase rings of each of said phase groups are each led together as a phase ring group of parallel phase rings from the winding connections to the external connections.
