Abstract
In a connection arrangement () for the stator winding of a turbo machine with two or more parallel circuits of individual conductors () per phase, the individual conductors belonging to one phase form a phase group () and run directly adjacent to one another in the stator body, the individual conductors of the winding are each connected from a winding connection () to an external connection () via a phase ring (), which runs concentrically with respect to the machine axis (). 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 () of a phase group each being led together as a phase ring group () from the winding connections () to the external connections ().
