Abstract
The invention relates to a stator, an electric machine comprising the stator, a vehicle comprising the electric machine, and a method for producing the stator. The stator comprises a stator laminated core and a housing element. The stator laminated core comprises a plurality of layered stator laminations, wherein each stator lamination has a plurality of tooth portions, each formed radially inwardly at an angular position, and indentations radially outwardly at each of the angular positions, each of which indentations has an at least partially curved edge having two radially outwardly curved edge portions, which meet at a point of intersection and describe an arc of a circle segment. The housing element comprises a cylindrical inner volume, in which the stator laminated core is arranged, the indentations forming cooling channels.
