Abstract
A stator of an electric machine includes a laminated core on which stator teeth and stator grooves are formed. A conductor bundle is arranged in each stator groove. A groove base channel extends in the axial direction and through which a coolant can flow. The groove base channel is formed between the groove base of the respective stator groove and the conductor bundle. A groove slot channel extends in the axial direction and is formed in the groove slot. The groove slot channel is fluidically connected to the groove base channel at at least one distributor point via a distributor connection that runs in the radial direction. The cooling path of the stator groove is formed such that a cooling flow is forced from the groove slot channel into the groove base channel and/or vice versa via the at least one distributor connection.
