A rotor assembly for an electrodynamic machine includes a lamination section with rotor laminations formed to define annular arrays of axial vents and rotor slots, with rotor conductor bars being disposed in the rotor slots, an end connector supported by the rotor conductor bars, wherein an axial space is formed between the end connector and the lamination section, and an annular guiding element arranged in the axial space between the end connector and the lamination section for guiding a cooling fluid flow in an axial direction.
