Various embodiments include stator for an electrical machine comprising: a stator winding; and a yoke with a plurality of slots. There are a plurality of conductor segments connected to one another, wherein each conductor segment has one respective axially internal inner section and two respective axially external outer sections. The respective inner section of each conductor segment is embedded into a respective slot. Ducts for coolant flow in the axial direction are formed at least in a portion of each of the slots. The stator defines, at least in a first axial end region, a first coolant chamber fluidically encapsulated from a surrounding area. The first coolant chamber surrounds at least a portion of the respective outer sections of each of the conductor segments situated in the first axial end region. The first coolant chamber is fluidically connected to the ducts to conduct coolant into and/or out of the ducts.
