Abstract
A stator () for an electric machine () includes a laminated core () arranged axially between a first end plate () and a second end plate (). A cooling line () for introducing a coolant into at least one distribution duct () at the particular end plate () is arranged outside the end plates () and the stator () and is fluidically connected to the at least one distribution duct () in the particular end plate (). The laminated core () includes multiple axial ducts () for guiding the coolant through the stator (). The axial ducts () are fluidically connected to the at least one distribution duct () in the particular end plate () for the inflow of the coolant. An outflow for the coolant is formed by at least one end-face opening () in the particular end plate (). The at least one opening () is configured for spraying the coolant out of the axial ducts () onto winding overhangs () of the stator ().
