Abstract
A stator body for a stator of an electric machine has a base body with a plurality of stator laminations. The base body extends in an axial direction from a first outer end face to an opposite second outer end face. The base body includes at least one first axial coolant channel which runs in the axial direction through the base body. The base body also includes at least one second axial coolant channel which runs in the axial direction through the base body. The at least one second axial coolant channel has a greater radial distance from a central longitudinal axis of the stator body than the at least one first axial coolant channel.
